118.26 | try a different motor in the Valencia | SNOMAS::LEE | | Mon Feb 16 1987 13:45 | 13 |
|
Hello,
An RS540 motor should have much, much less power than a Lemans 260,
the RS540 is what is sent as an entry level motor in most cars when
you first purchase them. The Lemans is just about the most powerful
motor you can use in a car, and still be able to run at least 4
minutes. I might also suggest checking the prop pitch, did the prop
come with that plane/motor in mind?
Good luck,
Lorrin Lee

118.25 | Valencias do fly | HPSCAD::WFIELD | | Mon Feb 16 1987 16:07 | 7 |
| A friend of mine has a valencia, and yes it does fly.
At first he had problems similar to what you are having.
The valencia did not havea lots of power and if he tried to climb
just a little to fast it was all over. He finally got used
to what it could do by hand launching from the top of a small
hill and when he lauched he did not have to worry about climbing
out before the plane had enough airspeed.

118.38 | Scat Cat --- I like them | SPKALI::THOMAS | | Thu Mar 05 1987 14:35 | 14 |
|
Scat Cat's build fast, straight and light. They have a semi
symetrical airfiol yet fly excellently inverted. With any engine
they can be a great sport plane. They are somewhat groovey.
They stay going where you point them. I flew mine until I had
a radio problem and it tracked will in a loop. I used to do
my entire sportsman pattern with it. Being light it had plenty
of vertical. One more excellent point is that they can be
slowed down to land gently. They make a good low wing plane for
someone new to low wingers if you power them with anything
from a .19 to a .35. With a .40 in them they should be flown
be someone that has had a little experience.

118.1 | Craft Air: Piece O' Cake | AKOV01::CAVANAGH | Well, I'm up here, how do I get down? | Wed Apr 08 1987 11:19 | 13 |
|
I just finished a Craft Air, Piece O' Cake. The kit was easy to build
but the materials left something to be desired. Much of the 1/4 x 1/8
balsa had the strength of sponge. I replace a lot of the balsa with
some I picked myself.
Although the kit I got was pretty good about the die cutting, I have
heard that some of these kits are mashed instead of cut.
I have not yet flown my 'POC', but hope to get it up this weekend (sounds
like a personal problem |-) ).

| I'm in the covering phase of my Piece O' Cake. The balsa in the
kit I got was good (not great) but the die cutting was the pits!
If you are going to buy a kit that has die cut pieces do yourself
a BIG favor and check the whole kit before putting down $.
I had the chance to assemble a Train-Air 40 for a friend. So far
this is the best kit I've seen. All precut pieces are sanded and
all the wing formers are the same size.

die-cutting (and consequent fit of the parts) very good, and ease of
assembly very good. Though I would've remembered some dicey moments
fitting the wing halves together.
Someday, when my engine comes back from the factory, I may even fly
it! :-)

I have just finished an Electra (a Gentle Lady was my first kit). I put an
Astro Cobalt 05 in it. It seems to fly well with the trim set up as per
instructions - at least as well as can be expected on a cloudy April afternoon
in North Carolina where the wind blows all directions at once! I like
Goldberg for the directions, there's never any confusion about what goes
where...

the directions are very easy to follow.As far as die cut piece's
they weren't to bad.The thing you have to remember is to cut the
piece's out with an exato knife do not "punch" them out.
I would prefer to have the part just drawin on the balsa and I
would cut it the way I would want it cut.
In the plans it specificly tells you that this aircraft is not
for the inexperienced builder.
Well that's my two cents worth.

| Many of the kits mentioned so far, I have never heard of. (actualy
I havn't heard of any of them :^) ).
Here in Europe we mostly see W.German made kits like ROBBE and GRAUPNER
Has anyone seen them in America?. (Does anyone want to see them!)
When I was in Ausie I built mostly from PILOT kits, made in Japan.
These were very good. Excelent die cut parts and good hard balsa
ribs etc. They obviously selected the balsa for the job as the bits
you had to sand were of softer density. Most of the hardware which
was model specific was included, and the other bits (Tank, wheels
etc) were left out so you could use cheaper local parts.
Now I have found a local supplier of Pilot kits and I am Building
one of their Quick Build 20 kits.
I wouln't mind trying something which will look a little different
at the flying field. Is anyone interested in an exchange? A European
kit for an American kit of about equal price.

| I built the SIG Citabria for my first scale effort, the kit had
good wood and decent hardware, but the documentation was sketchy.
Some day if I ever become a scratch builder I will probably thank
SIG for forcing me to figure a lot of stuff out on my own. With
an ENYA .46 4-stroke it flies great.
I've done the Great Planes Super Sportster .20 and am building
the Great Planes CAP-21 now. These are both excellent kits with
good wood and hardware, and very thorough documentation. The
documentation for the CAP also includes complete trimming guidelines.
I think the Great Planes stuff is more expensive but you do get
what you pay for.

118.13 | Nasty Sports Air 20 Experience | CAD::SPANOS | | Fri Apr 24 1987 12:08 | 23 |
|
Regarding kit qualities, I had only positive experiences with Goldberg
(Eaglet, Falcon). The last kit I built from G. Planes (Sports Air 20)
however, had a vary nasty surprise in store for me at the very end...
The kit was great, the building fast, the documentation excellent. But
during the maiden flight, while attempting a rather sharp reverse
Immelmann, I had the distinct displeasure of watching helplessly as the
left half of the horizontal stab parted company of the rest of the craft,
and my pride and joy span out of control, luckilly away from any
spectators.
Upon inspection of the pieces, I noticed that the horizontal stab (which
consists of a single 3/8 inch thick balsa sheet) had failed at the root,
apparently due to excessive flight loads! I know it seems hard to believe,
but it happened. Upon closer examination, I noticed that the wood grain
along the line of the failure was not very smooth. Well, better luck next
time...

118.17 | Sig Riser | BARNUM::WALTER | | Thu Jun 25 1987 14:25 | 13 |
| I just completed a Sig Riser sailplane (haven't flown it yet). It's the
first kit I've built so I have nothing to compare it to. However, I'd say
the overall quality was pretty good. Instructions were clear and helpful,
all materials were there and the right size, and the die cut parts fit just
fine. My only complaint (a minor one) was the quality of the balsa varied
from piece to piece. I'd give it about an 8.
By the way, I used both Super Monokote and Ultracote to cover it, and found
the Ultracote easier to work with, but a little bit heavier.

118.36 | I liked Zimpro | SPKALI::THOMAS | | Tue Oct 06 1987 11:32 | 18 |
|
The kit quality was Excellent with the exception of the fiberglass
cowl that I would rate a Good. The fiberglass cowl had aa little
cloth weave that wasn't filled. All other aspects of the kit were
excellent. I only made two changes. The first change was to the
aileron torque rods. The ones supplied in the kit were a two piece
arangement. There was a piece that had to be soldered to the torque
rod so that the push rod from the servo could be connected to the
torque rod. I replaced these with Goldberg (large) torque rods.
The second change was to the hinges. I opted for the Sig nylon
material rather than use the pin hinges supplied. Personal preference.
The wood quality was excellent and the ship is light. There were
also excellent instructions.
The only thing is that these kits aren't cheap!

118.32 | Dynaflite Butterfly | LEODLN::SCANTLEN | | Mon Feb 08 1988 08:10 | 10 |
| I'd built and flown the Butterfly when it was a Craft-Air company.
I found that the wood quality was mediocre, and it built slightly
tail heavy. It could be hand launched without wheels with ease,
and was very stable with good glide characteristics. It is in many
respects 'hands off' in that it is a leisurely airplane to fly.
Mine was rekitted due to radio failure, but should be difficult
to destroy if you've got some flight time in.

118.19 | Goldberg Super Chipmunk | SPKALI::THOMAS | | Fri Mar 11 1988 10:34 | 16 |
|
I've seen this kit. What is plastic is mainly the cowl and some
additional blisters around the retracts. I however wouldn't recomment
this plane as a first low winger. Chipmunk's are limited in their
wing area and can be nasty at slower speeds. If I were you and you
do like Chipmunk's I would buy the Goldberg Chipmunk and put it
on the shelf for a second or third low winger. If you want to buy
a less expensive kit for the first low winger look at a Balsa USA
Smoothie (tail dragger) of the Moonraker (trike gear). they are
the same plane with suttle differences. With a non schnerled .40
they make great first time low wingers. After you get this ship
in the air and have a couple of flights on it then you could go
back and start the Chipmunk. By the time it would be ready to fly
you should have sufficient time to keep the chipmunk in one piece.

| > Kyosho. They market the H*LL (you're right about the missing vowels!)
> out of the Valencia, and I haven't heard any glowing reports on
Dan,
The Valencia was the plane that convinced me never to buy another
ARF so long as I lived. Although it did fly pretty well, decent
rate of climb and pretty stable inverted flight, handling was a
little squirrely, glide was kind-a fast. The biggest problem was
that the fuse was made of that plastic that they make potato salad
type containers out of. Not the vacuum formed thin stuff, but the
stuff that is great for mixing epoxy on, since no glue in the
world (that I know of, anyway) will stick to it! As a result of
this design oversite (or maybe intentional) on the part of Kyosho,
if you broke the fuse, you just could not repair the stupid thing.
This problem was compounded by the fact that my fuse broke as a
result of a wing folding when I pulled out of a dive, so it broke
in a LOT of places (I think "auger" is the term that best
described the flight characteristics exhibited by the plane).
Anyway, it was the fastest $150 I'de ever spent. Bought it on a
Saturday, threw it in the trash on Sunday.
The rule I use now for my planes is, if I can't fix them when they
break, I won't bother wasting my money on them.

| Bob,
I haven't built one but I _have_ flown the Astro-Hog, several of
them in fact.
From the standpoint of flyability, I wouldn't hesitate to recommend
it to anyone. It's stable and gentle while remaining responsive.
This means it'll forgive some amount of "dumb-thumbs" but has the
performance to take one well into aerobatics. It might even make
a reasonable trainer for a student with good aptitude, though I
wouldn't advise that to just everyone.

118.20 | Back to the original question... | RAVEN1::HANEY | | Sun Jul 31 1988 23:28 | 37 |
| The Great Planes is the best on the market. Thier die cutting,
overall packageing and documentation, wood (all), would be in my
opinion a 99 out of a 100. Some planes I've built by other
companies...
Balsa USA Sopwith Pup 92 out of 100
Flown with zenoah G62. Out of sight vertical climb.
Or will putt putt excellant.
Goldberg Anna. Cub 85 out of 100
Flown with OS61FS. Excellant all around handling. With 12-6
prop= 45 min. flying time with 12oz. tank.
Bud Nosen 9 Ft. Citabria 60 out of 100
Flown with G38. If you buy one of these kits, throw away the
original wood. Replace it with your own and beef it up about double.
Then you have got a good plane.
ACE 4-120 Bipe 95 out of 100
Flown with OS120 Surpass. Die cutting could be a little better.
Flies perfectly.
Top Flite Kitty Wake 50 out of 100
Flown with OS28FSR. Extremely fast, extrem~rely poor construction.
Building methods are about twenty years old. Varied wood quality.

118.45 | Easy 100 is on the board! | 30363::SNOW | | Wed Aug 24 1988 09:08 | 32 |

I started work on the Easy 100 last night, and the more I look
over the kit, the more impressed with it I get! The wood quality
is excellent, the die-cutting is some of the best I've seen, and
I appreciate the rolled, not folded, plans.
I wouldn't, however, reccomend this as a first time builders
kit. You get the plans, which are very crisp and clean, and maybe
a page and a half of notes. Other than that you're on your own.
I do have the copy of the construction article that was in the July
issue of RCM which will be helpful. It's also intersting to note
the changes that were made to the construction from the plans in
the mag to what was finally kitted.
I would imagine with my 12 year old cracking the whip over me,
(technically this is HIS plane!) I'm looking at about 3 weeks to
get the plane completed and ready to fly. Part of that depends on
when I can get the $50 or so together to order the Davis Diesel
muffler and soft mounts. I'd love to make this in the tail-dragger
version, but son is insisting on a tri-gear set-up. Oh well, if
this plane flies as well as advertised I might just be persuaded
to order another for myself. At $38.00, why not.

118.15 | Falcon 56 and Senior Falcon | PNO::CASEYA | THE DESERT RAT (I-RC-AV8) | Mon Sep 12 1988 11:41 | 29 |
| KAY, DOUG,
The Falcon-56 and Senior Falcon continue, after some 25-years, to
be two of the finest beginner and intermediate ships around. As
Kay says, the Falcon may not be as "automatic" in terms of stability
in the hands of a novice but I _personally_ consider this a plus
as it allows the student to actually "feel" the airplane and what
his control-inputs are doing to it. Far too many times I've seen
students who learned on the flat-bottom winged, ultra-stable, rudder/
elevator birds have to essentially learn all over again when they
graduate to a more advanced aircraft. Set up with the controls
nice and gentle, the Falcon makes a wonderful trainer and, after
the basics are learned, tightening up the controls yields a great
advanced trainer which will carry one through the rudiments of
aerobatics. As Kay also stated, set up correctly, the Falcon makes
an excellent sport ship with acceptable aerobatic capabilities.
Incidentally, I learned to fly R/C on an old, busted up, hand-me-down
Senior Falcon nearly 25-years ago so, like Kay, I also have a warm
spot in my heart for it but I have seen/flown enough (if not all)
of the so called "perfect-trainers" to know that the Falcon would
be my choice again, hands-down. Whenever I'm asked, I'll always
recommend any of the "Stik" types or the venerable Falcon!

118.43 | Sterling PT-17 | PNO::CASEYA | THE DESERT RAT (I-RC-AV8) | Tue Oct 04 1988 16:18 | 30 |
| Tom,
If you choose to build Sterling's PT-17, be prepared to work with
beau coups parts. Not that that necessarily makes it bad, it's
just that Sterling, like the old, old Berkley kits, uses many, many
parts in its construction. This will be a definite departure from
the trainer-type kits of today that have a total parts count of
about 24; Sterling kits are built-like-a-bridge but are tough as
an old boot. The main thing you have to watch out for is not to
let it get too heavy on you.
This should more correctly go in Ramblings but I'll never forget
flying Ted White's Sterling Stearman in the bomb-drop event at the
El Paso Sun Carnival Fun-Fly some 20 or so years ago. Failing to
find a good place to rubberband on the paper cup, we opted to simply
put the water-balloon in the rear cockpit. You had to be careful
in the turns not to accidentally lose the balloon but it worked
to perfection; I'd approach the target straight-on, in a shallow
dive then pull up vertically, directly over the target...pushing
the bird back to level with down-elevator would pitch the balloon
out, almost motionless for an instant, then the balloon'd fall straight
down [hopefully] right on target. I got lucky and won the event
that year with the tired, overweight old Stearman which Ted had
powered with an old Fox .74. A really fun experience!

118.21 | World Engines Enticer | SA1794::TENEROWICZT | | Wed May 17 1989 10:14 | 27 |
|
Last night late, I started construction of a World Engines kit
called the Enticer. It's a Dick Sapoulas (sp) design. Very basic.
At the last DEC Fly-In one of the CRRC guys had a dragon lady at
the field with an OS120 in it. This tickled my fancy so I started
looking for a large sized plane. The Dragon Lady and the Nutten
Special are ARF's kind of but to must money for what I wanted so
I decided on the enticer at 55.00 for the kit. For the most part
the parts are die cut. This is ok but some crunching is evident.
If your a new commer to building this is not the kit for you. The
instructions were one page. They have since been filed. The plane
sports an 18% wing thickness with 930 squares and a wingspan of
72 inches. It was designed for the Maloney 120 but I've opted to
install an Enya R120. I figure that I'll be able to take 8 oz. out
of the tail by builsing ut the vertical stab abd rudder. They are
solid sheet stock in the kit. If I don't build them up I'll put
some big lightening holes in them. Other than that I think I'm going
to install a round cowl with blisters on it rather than the 1/2"
sheet thock cowl that is in the kit. It has large surfaces with
the horizontal stab set on the engines thrust line. With the incedences
set at 0,0,0 with the weight around 9 lbs and the semetrical wing
section it should be somewhat aerobatic.
As of last night I have one wing panel 50% built. I should get
this finished before my club meeting tonight.

118.44 | comment on the GP Tiporare | SA1794::TENEROWICZT | | Thu Jun 22 1989 13:09 | 16 |
| Not worth the money.
The tipo is OK however not the Tipo most seen. A couple of places
make Tipo's. The Illusion never really made it. Probably because
when it came out Dave Brown, the plane designer and Chief user
was over the hill and wasn't on the top hence the airframe didn't
get the exposure.
For AMA pattern look at an FK Career 60. It's a Jap copy of the
Tipo. Comes with presheeted wings/stabs abd all bulkheads installed.
A little heavier than one could build but for the time and money
(only 130.00) it's a great deal. Put a YS in it and you'll have
a winner.

Well.... after doing everything possible ( and reading note 231.*
) I have determined that, at best, it's going to fly too slowly
to really learn on. It's fun to put it up there and fight the wind,
but that's about all it'll do.
I've stepped up construction on the C.G. Falcon 56....it's really
going together fast. The die cut parts fit tight, and I'm MUCH more
aware about how heavy I am building. I'm building it with ailerons,
and it will be powered by a .40 sized engine.

| Doug,
You'll like the Falcon-56. It's a veteran design (goes back 25-years
or more) but it remains a great trainer and early-intermediate ship.
Annnnd, it ain't half bad looking either..., unlike many of today's
so-called trainers (but we won't get into that) :B^).

118.23 | Spinks Akromaster | ESASE::CULLEN | | Thu Sep 14 1989 11:05 | 10 |
|
Anyone in notes-land every built a 'Spinks Akromaster' ? The kit I am looking
at is a Pilot kit. As per normal Pilot standards everything is top quality.
It is a 40/45 powered 2.7-3Kg, 1.65 meter wingspan model. My only reservation
is the amount of plastic involved for the front cowling.
Any comments ?

Pilot plastic tends to be thin. If used I'd suggest you laminate
fiberglas on the inside of the plastic. Look at the Circus Hobbies
Akromaster. I think they make a .60 two stroke and 1.2 four stroke
version.

118.27 | Displeased with Pattern Tek | SA1794::TENEROWICZT | | Mon Dec 18 1989 14:06 | 24 |

OK, To start things off I ordered a kit from a compamy in Ca.
Pattrem Tek. It was the Supra Star. "A direct copy of the EZ 60
sized Supra Star" in carbon reenforced fiberglas. The kit featured
plug in wings and incidence adjusters. What I got...
I ordered the semi-kit. It contained a fiberglas fuse that had
an external gell coating. At least parts of it had a gell coat.
The gell coat was missing,scratched or had voids in a number of
areas. The inside of the fuse was covered with a sheet of 1/8"
foam board that appeared to have a coating of resin over it. The
cockpit cover was pitted and the canopy looked like it had been
heated to much or the mold had been dusty. The kit also featured
foam cores for the wing and horizontal stab. The stabs cores were
fine. The wings cores were ok except for the leading edges which
looked like the hot wire was dragged over them. They exhibited a
lot of ridges and gouges. The fuse itself weighted 1.8 lbs. Heavy.
That's all. I called them and told them of my displeasure. They
said they would replace anything that wasn't to my satisfaction
or send me a kit of one of their other designs. I declined and
sent them the kit back via UPS. I have yet to see my money.

I just received from Joe Pinkston models a ship called the Super
Lucky Fly II. Its a 90% built ARF with foam wings covered with 1/16
balsa. What caught my eye was that the fusalage was prebuilt with
excellent quality. It takes a 60 engine, wing span of 61 inches and
651 sq in wing area. Its currently advertised in RCM and the AMA
magazine. Cost is $99.00 plus S&H. I will let you know what it takes to
finish it up but for now it looks well worth it.

118.54 | ACE Whiz 40 | TRNING::FRANCO | Spin, crash and burn! | Tue Apr 07 1992 09:46 | 49 |
|
I have just started the new ACE Whiz 40, a highwing, 40 size "trainer".
(I say "trainer" because it is advertised as so and has many
characteristics of one.)
My comments about this kit are as follows.
It is said to be a terrific "first time" kit with a tutorial approach
in the instructions. NOT SO!!! It may be a first time kit for
some people but I can almost guarantee you it will come out wrong.
ACE has done much to provide you with enough printed material to
start your own recycling plant. Three sets of prints, two construction
manuals and multiple bags of parts. (I will say that this kit does
include everything you need to fly except engine, radio and covering.
I mean they even give you fuel line and foam!)
Here are some of the "gotchas" I have encountered thus far. (BTW,
I have been building planes for 4 years and have built many ACE
kits and was impressed with them all. This is their first disaster.)
First, one of the "prints" is a parts layout showing all the respective
ply and balsa die-cut pieces. On this sheet they show you a ply
part labeled "Crutch rear". It is "suppose" to fit on the top of
the fuse from about mid-fuse to the tail. WRONG!!! What is labeled
is actually the BOTTOM REAR fuse section not the top. Also, the
correct crutch rear is labeled "bottom rear fuse section."
Secondly, when drilling and mounting the firewall they forget to
tell you that the firewall is beveled on both top and bottom. This
bevel allows the bottom front of the fuse to meet the firewall
correctly. Same for the top of the fuse. A first time kit builder
has a 50/50 chance of drilling the holes correctly so that the bevels
are correct.
Third, the die-cutting of the ply is terrible. None of the pieces
are die-cut cleanly. All require extensive work with a knife and
a saw to remove.
Finally, the matching of of "interlocking tabs" is way off, so bad
that even ACE has supplied a piece of ply to cover over a gap, and
I'm talking 1/8", between the fuse bottom middle and fuse bottom
tail pieces. Oh, one more note, the main landing gear plate, a
piece of 1/4" maple, is about 1/8" to wide to fit in between the
inner fuse sides. It seems that the designer forgot to compensate
for the inner fuse side braces that cover the gap between the front and
rear fuse sides.
Well, I guess that's it for now. All I can say is "buyer beware".

| Franco,
I'd suggest that you gather up your comments and fire off a letter
to Ace. You never know what it may yield you. At any rate, I'm sure
they (Ace) would be interested in some comments from a consumer.

| Yeah, really. You've done a fine job of documenting the problems with
the kit, and from my past dealings with them, I'm sure Ace wants to
know about the kit.
|
118.57 | Thanks for your insight | TRNING::FRANCO | Spin, crash and burn! | Fri Apr 10 1992 11:37 | 9 |

Thanks guys for your recommendations on firing off a letter to ACE.
AS soon as I finish this reply I will type up a quick note to them.
I too felt that they should know but decided to just "let it go",
however now I've changed my mind.
Again, thanks.

| Rich,
The Wizz 40 is the plane I was considering for my first plane in 20+
years. Since I'm sure that I would put the plane through several tough
manovers, such as cartwheel end over end when landing, or the ground
is actually three feet higher then expected, What I am more interested
in, is how sturdy a plane is it? It it a solid plank covered fuse? I
can't tell from the picture in the Tower flier if it has a cockpit
area, or if it is solid. Can you fill me in?
Walt Miller

118.59 | | CXDOCS::TAVARES | John-Stay low, keep moving | Mon Apr 13 1992 10:58 | 14 |
| Walt, I'm not saying that the Whizard (or whatever) isn't a good
plane, but I suggest that you pick up one of the established trainers,
such as the Great Planes PT40. You will not be taking any chances
with such a plane.
Additionally, instructors have a rather nasty bias to such things I've
noticed. If you show up with an odd-ball they tend to blame problems
in training on your equipment. You'll spend more time fooling around
trying to make the changes they suggest than you'd spend actually
flying.
We have quite a body of opinion in this file about trainers, learning
to fly, and instructors. Please take the time to skim over this
material; its as valid today as when it was written.

118.60 | Get Local Advice | LEDS::WATT | | Mon Apr 13 1992 11:15 | 9 |
| I would suggest that you check out your local club, hook up with an
instructor, and ask their opinions on trainers. Go with what's popular
at the club you plan to join! You will get better help if you have a
plane that the instructors are familiar with. There are no real
bargains in trainers - they're all about the same cost in the same size
range. Some are more work to build than others though.

Over the weekend I had a chance to look over my new PICA Junkmeister
kit. Really a fine design and quality kit. The wood (so far) seem
ideally choosen for the tasks. With a cockpit and fake radial engine
the weight should come out in the 10 lbs range. Building techniques
for the fuse are different.
In most cases the designers choose either the top of the bottom of the
fuse a a reference to build the fuse over a plans. This is due in part
because for the most cases one of these areas is usually flat and
straight. On the Junkmeister, neither is straight. So the designer
made a straight surface by spliting the fuse into a top and a bottom
section. To assemble the fuse tu build the top section and then add
the pieces for the bottom section. the fuse is assembled first
followed by the tail feathers and then the wings. I'm now delayed in
finishing my Seamaster for a week until I get some new covering. I'll
probably start the Junkmeister construction tonight.

118.62 | Sorry I'm late, Ma. | TRNING::FRANCO | Spin, crash and burn! | Mon May 04 1992 15:23 | 33 |
| Re -.58
Walt,
Sorry I haven't gooten back sooner but DEC ha skept me busy. (I
guess in this day that's good.)
Well alot of these guys have given you some good advice on trainers.
I will answer your question(s) about the palne being sturdy, plank
fuse and cockpit.
I have built many planes in the past 3 years, around 11 and this
one, in my opinion is NOT that well built. It has a solid fuse
but many of the pieces are glued togther to give you one big piece.
Example: I have built an Airtronics JetFire 40 which has a one piece
solid ply fuse sides and top. The bottom is ply glued to balsa.
The Whiz has sides and bottms that are glued together. In fact
in my original reply I mentioned that they must have made an
engineering boo boo on the fuse bottom. They supply a piece of
ply to cover an opening in the bottom of the fuse made by two
"mismatched" pieces. Not what I would call quality or sturdy.
As for the "cockpit" all you get is a built up side of the fuse.
You could probably put something in there to make it more realistic
but again it is all solid ply. This built up area makes it a little
bit difficult to get at your servos if your hands are really big.
You have to reach down about 7" to the servo rails and you feel
like your "leaning over" the plane.
To whomever reads my replies: Please understand I have no complaints
about ACE in general. I have built their Bingo, Big Bingo and the
4-120 Bipe which are all excellent kits.

| Thanks for the reply Rich,
I tried to get to the last CMRC? meeting at TAY a couple weeks ago,
but DECWorld kept me busy until the wee hours of the night. I hope I
can get to the next one in MRO. I know Ken Berstal and he is the one
whom left me know about the club.
I still have not selected a plane, based on the prior replies. I will
let that up to the experts but I still have some preferences although
they may not be for the right reasons. (But I'll listen!!)
I also have not selected an engine, but after reading this notes file
and the DECRCM, it appears that OS is the way to go. OS was the engine
of choice +20 years ago!!
I am also considering the X-347 as my radio of choice, after following
the comments in this notes file.
I figure that, if I'm going to return to RC, DO IT RIGHT!! 8^;
I'd rather put the money up front now and get it over with, rather
than upgrade later and spend 30-50% MORE than what I would have spent
the first time by doing it right.

Has anyone seen, built, or have any knowledge around Cressline

| Bruce,
I don't know anything about the Cressline Models LONG-EZ other than it looked
like more than my neihbor wanted to pay. See' he's interested in building a
full size version of the four-place EZ and was wondering what it would cost
to build a model first to investigate the flight characteristics. I took a
gander thru the Tower catalog and decided his wife would never let him spend
that kind of money. I did better with the RCM plans catalog. There are several
plans for a couple of different EZ versions in there. You might want to check
it out. If you don't have the catalog (an excellent refernce tool for
daydreaming) I can copy the revelant pages for you.

If the kit is worth $119.95 i'll buy it. If someone bought it and got

118.67 | Flair Puppeteer | BAHTAT::EATON_N | Personal Name Removed to Save Costs | Thu Feb 10 1994 09:54 | 70 |
| Having described the first flight of my Flair Puppeteer I suppose it
might be a good idea to post a brief description of the kit, so here
goes:
The Puppeteer is loosely based on the Sopwith Pup WWI fighter
plane. It spans 50 inches, and is of all built up construction. You get
a spun aluminium cowl, aluminium cabane struts, wire for the
undercarriage, two *large* plan sheets (very clearly drawn), an
instruction booklet and a *lot* of wood! It looks a bit daunting at
first sight, but construction is actually remarkably quick. I built it
pretty much as per the plan (who am I to try to "improve" a Dudley
Pattinson design? 8^). The only real mod I made was to build a box
on the back of the firewall to accomodate the rather large engine I
am using. After taking the advice of the good folks in here I built 2
degrees of downthrust into this box, and used 2 degrees of right
thrust on the mount. This seems to work just fine (thanks to all
those who advised on this!).
Wing ribs are cut from lite-ply, with large cut outs for lightening.
These are cut incredibly accurately, they really just drop into place.
This gives you two huge wings to admire whilst you build the
fuselage. This is a balsa box, with formers over it to support the
front sheeting and longerons and stringers to build up the rear end.
Tail feathers are built up structures.
Construction was pretty smooth, with very few if any gotchas. All
you need to be is awake and fairly sober and you can't really go
wrong. Having said that I did manage to fit the lower wing dowels in
the wrong place, but this was definitely me being stupid.
One thing you need to know about this kit is that after you've got it
you still have a bit of money to spend, or extra effort to put in. I
bought: a pair of 5 inch "antique" wheels, a 1/5th scale machine
gun, a 1/5th scale pilot, a set of markings, and a lot of covering! I
used Solartex for the covering and I used 4 metres of green, 4
metres of linen, and a metre of silver. I didn't cut the covering very
intelligently, and I did make a few mistakes, but you're still going to
use a lot (this ends up being quite a big plane).
As this was my first biplane I was worried about everything being
aligned properly. I needn't have. When I first trial assembled it
everything just lined up and fitted. What a relief! What a *pretty*
aeroplane! I took loads of photos with the structure "naked" (kinky
beast!)
I used solartex hinges for the ailerons (as recommended) and
mylar strip for the tail end. This was the only problem with the
materials supplied with the kit, in that the hinges supplied were
useless. As soon as they were flexed more that about 50 degrees
they cracked and fell apart. I'm glad I found that out on the ground!
I just substituted some mylar strip and all was well. This may just
have been a bad batch of hinges.
With the Laser .70 in the nose very little nose weight was required
(about two ounces). Final weight was in the region of eight pounds,
which gives a very low wing loading.
Flying I have described elsewhere. Suffice to say that it is exactly
as advertised. It looks great, doesn't take up the whole sky, and
flies s-l-o-w-l-y. A real pleasure to fly.
So I am very very pleased with this kit. ARTF it ain't, you have to
do a bit of work, but if you like building this is a real pleasure. The
end results are very worthwhile.
Now I'm looking at the "Baronette" from the same manufacturer,
this one's based on the Fokker Triplane! 8^)

118.70 | Need info on Sterling TriPacer kit | MKOTS3::MARRONE | | Wed May 11 1994 14:00 | 35 |
| I looked thru this file for something on the Sterling Cessna TriPacer
135, but didn't find anything. A member of my club built one and it
crashed on the maiden flight. He had modified the tail feathers to be
more scale-like, and we think there was just too much rudder and
elevator for it to be stable. The kit calls for a _very_ small
elevator and rudder, clearly not to scale, which he thought looked
totally inappropriate, so he modified them to be true scale size.
The effect of this change was to make the control surfaces look too big
for this short, stubby plane, so I immediately suspected he was going
to have some trouble. I told him to cut way back on the elevator
throw, but it might have still been way too much.
At any rate, he attempted a takeoff, and shortly into the rollout, it
seemed to lift off by itself. It them immediately began a fairly sharp
left turn as if the torque effect was pulling it left. He said he
tried to give it some down elevator to get the airspeed up, but it just
snapped clockwise and went in at full throttle. The damage wasn't too
bad considering the impact, and its repairable.
Dan Weier and I tried to analyze the situation. On one hand it seemed
as though the plane took off prematurely and didn't have enough
airspeed. That alone might explain some of the behavior, and would
account for the right (highest) wing stalling and causing the clockwise
snap. However, if the airspeed was sufficient, and somehow he had given
it some up elevator instead of down as he claims, then the large
elevator could have caused it to snap. Although we both
agree he had way too much elevator throw, we weren't entirely sure what
happened given the observed facts.
Has anyone ever had experience building and/or flying this particular
kit? Any information would be helpful.
-Joe

118.71 | Some thoughts | SNAX::SMITH | I FEEL THE NEED | Wed May 11 1994 15:14 | 14 |
| Minor nit.....the Tri-pacer (unless there's more than one) is made
by Piper, not Cessna.
I would think it would depend on how "scale" the kit was. The real deal
is a VERY highly loaded, short coupled airplane. There not forgiving
at all and fishtail in the air due to being so short coupled. They also
tend to porpous (sp?) alot (read not very stable in pitch). It's the
only airplane I've ever flown in that made me sick on a perfectly calm
day.
I would think that a kit of this plane would have to be flown fast
to keep it flying. Also, if it is anywhere near scale in airfoil, you
probably need a lot of rudder on takeoff and landing to compensate for
ineffective ailerons at slower speeds.

| I flew a cub that did that to me. It needed coupled rudder. The
ailerons reversed at slow speed and it flipped in just like a snap
roll.
With rudder permanently coupled it was a delight to fly.
Wing loading over 25 ozs per sq ft also can do the same thing, I know
:-)

| (Don't like to mention that I've had dealings with power...)
But as 'E' describes I had exactly the same reversal problems with
ailerons on a high wing Twin engine machine. It was realy bad at low speed
on take off, and of course you're natural evasive action is to more of the
same control movement in... bang... plastic bag...

118.74 | Further Thinking.... | WMOIS::WEIER | Wings are just a place to hang Ailerons | Thu May 12 1994 10:00 | 22 |
|
First of all, could someone explain "aileron reversal" to me? I have
never heard of this phenomenom ( except when the servo's were actually
reversed, or in full scale aircraft at very high ie; supersonic
speeds.)
In thinking further about the Tri Pacer, I think Steve is on the
right track. The plane is VERY short coupled, thereby minimising
stability. An extreme example of this is a Gremlin. There is a REASON
the CG needs to be 12-15% instead of the normal 25-30% on a Gremlin.
With the Tripacer, the CG may need to be moved slightly forward. The
Tripacer's CG is currently about 25%.
The kit also has very short wings, and although I didn't lift it,
I suspect the wing loading is high.
Add to this it might be out of trim, his elevator may be too big,
there is probably too much elevator throw, there is no wing wash / stall
strips to prevent tip stall, no downthrust/sidethrust in the engine, no
expo / mixing capabilities on his Max-6 radio, and the pilot is relatively
inexperienced in the use of rudder, and you can find more than enough
possible causes of the problem.
|
118.75 | I'll try and explain it... | CSTEAM::HENDERSON | Competition is Fun: Dtn 297-6180, MRO4 | Thu May 12 1994 11:03 | 32 |
| The ailerons work by interupting the airflow and moving the wing in the
opposite direction to that in which they were moved. So if you move an
aileron up the wing panel will go down. this is what happens as long as
there is a normal airflow over the wing.
Reversal is when the wing goes up if the aileron is moved up. In flying
terms left aileron would give a right rolling effect. This usually only
seen to occur when a plane is moving very slowly as in take-off
situations.
There are several explanations but the one that I prefer is that no
airflow is reaching the top of the aileron so the aileron creates a
vacuum on the wrong side.
Usually the ailerons just become ineffective at slow speed but in some
cases, as more aileron throw is applied, they nastily cause a reverse
effect. Differential with more up than down helps solve some of this.
Coupled rudder aleviates the aileron ineffectiveness at slow speeds.
You might have noticed that when hovering a plane into the wind you
have had to use rudder instead of ailerons to keep your heading.
Theory #99 based on known facts...
There could also be a design problem with this plane. As a rule of
thumb the stab and elev. area should be 25% of the wing area. An
elevator stall causes a lovely snap at slow speeds.
Regards,
Eric.

118.76 | Aileron Reversal near stall | KAY::FISHER | BXB2-2/G08 DTN 293-5695 | Thu May 12 1994 12:45 | 25 |
| Aileron reversal - put another way.
Your at or near stall.
Now if the plane rolls slightly to the left (port)
your natural reaction is to add some right aileron.
This lowers the aileron on the left wing and raises
the aileron on the right wing. If you were flying
at normal speed all is well - but since you are at
or near stall lowering the aileron on the left wing
greatly increases the angle of attack.
Again - since you are at or near stall increasing
the angle of attack at the wing tip stalls it and
the left wing looses all lift. It is morally
the equivalent of adding wash-IN.
The cure as Eric said is to correct roll with rudder
at low speeds or as Eric does - NEVER FLY SLOW!

118.77 | | MKOTS3::MARRONE | | Thu May 12 1994 13:39 | 26 |
| Kay, what happened was just the opposite of what you described. The
plane was banking left, then suddenly snapped clockwise to the right.
If he was giving it right aileron input to correct for the left bank,
then it surely responded correctly and rolled right. But if that's the
case, the right aileron input not only banked it right, it also caused
it to snap over.
I don't think ailerons alone can induce a snap, so I believe he was
also applying some elevator, and with the large surface and large
throw, it wouldn't have taken much for the combined right aileron plus
some elevator to cause the snap roll.
But this theory of reversal has me confused, and I don't know if that
was the cause here.
From experience flying the Aeromaster, I _know_ you must take off
with rudder, NOT aileron control, and I have to stay on the rudder until
its fully up to speed and altitude. SHort coupled planes with large
elevator surfaces teach you all about the rudder, and it may be that
Doug didn't work the rudder after liftoff.
BTW, it was pointed out this is a Piper, not a Cessna. I goofed on
that. This is one FAT, short plane. Fully looking. It looks like it
would be squirrily as h*ll.

I have to admit, my aerodynamics are rusty, but I seem to remember
some planes will"tuck", and turn into the lower wing when they stall in
a turn, but others will "go over the top", and turn toward the top
wing. I believe the situation also varies due to certain conditions.
Accelerated Stall:
The stall speed increases as you increase the bank ( when
MAINTAINING altitude ).
Ailerons don't cause the snap roll, but as you bank an airplane
by using the ailerons, you need to add elevator to maintain altitude.
This causes in increase in the Angle of Attack, and VOILA all of a
sudden stall speed is reached (at a higher airspeed than would occur
in level flight).
AILERON REVERSAL
I can understand aileron's being blanketed and inneffective, but I
am still not convinced regarding aileron "reversal". What could be
concieved as reversal is just the top wing stalling, and then dropping.
Ex: Left aileron is applied while climbing. The plane starts
turning, the stall speed increases in the left climbing turn.
The wing stalls, and the right wing drops. Left aileron is
applied, and the wing continues turning to the right, because
it is a stalled condition. The correction would be to lower the
nose first, get the wing flying again, and THEN apply
left rudder/aileron to level the wings.
The rudder is used at low speed because:
1. It keeps the wings level so they provide maximum lift for
climbing, maintaining altitude, etc.
2. The ailerons could be blanketed / inneffective at slow
airspeeds/high angle of attack.
3. To provide directional control on takeoff and landing.

| After a recent wing failure on my fun scale Eindecker, I find my
self with a three channel radio and a .074 queen bee engine in need
of a home. Im considering the house of balsa's aniversary edition
P-51 mustang. Any body out there every build a house of balsa kit?
Thanks, Jim
