666.1 | Build it Right, not fast! | USRCV1::BLUMJ | | Mon Aug 22 1988 10:57 | 14 |
| Unless you are one heck of fast builder, you might be putting too
much pressure on yourself to get this kit done in less than a month.
The Aquilla, though a mid seventies design, still is a very competitive
ship in capable hands. I was just at a contest this weekend and
Pete Carr(President of National Soaring Society and editor of it's
magazine) still flys one! This kit has certainly made the rounds,
take your time, build it right and you will have a beautiful glider.
By the way, I heard Airtronics is thinking of offering this kit
again.
Good luck,
Jim

666.2 | fast?? nahh 11 I plan to sweat a lot | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Mon Aug 22 1988 11:40 | 10 |
| I'm not particularly fast.. I just plan to put in a pile of hours
(3-4 every night).
I pride myself on being fussy about my building..I plan to be extra
fussy because gliders must be built just right..
will keep you posted.

666.3 | Use spoilers/build light | USRCV1::BLUMJ | | Mon Aug 22 1988 13:48 | 12 |
| Another thing just came to mind. I do not know what your previous
glider experience is, but I would recommend putting spoilers on
this ship. If you ever plan to enter a contest or do not have a
huge landing area the spoilers will prove helpful. My first large
ship(paragon-118") was built without them and it can be difficult
to land in a tight field. Also not knowing your previous building
projects, it is important with gliders to keep the weight down-go
easy on the epoxy. I made this mistake on the Paragon which hurts
it's calm air soaring ability.

Mark,
I got into gliders just two weeks ago. As you probably
read in the notes file I managed to build it in a week - probably
about 30 hours - which I wouldn't recommend. What I wanted to
tell you is firstly that I don't miss spoilers. At the
competition the ones that really could put spoilers to good use
had flaps too and extended flaps and spoilers at the same time.
The angle they come down at is really spooky. The other thing is
that you will LOVE it. Saturday I found my first real thermal
and went up to a couple of thousand feet and could have stayed
there forever. I lent someone else the transmitter and he got it
too far down, so the flight ended after just over 10 minutes.
The Metric really flies extremely well.
Go for it.

666.6 | Thoughts | AKOV11::KAUFMANN | | Tue Aug 23 1988 09:14 | 4 |
| I've considered spoilers in my next glider, but give some thought
to a take-down wing (collapsable wing ???) whatever. My glider spans
78 inches and I have a hard time fitting it in the car. Good luck.

666.7 | Day 1 | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Tue Aug 23 1988 10:49 | 17 |
| worked about 3.5 hrs last night..Kitted the stab and got one side
half assembled. This is dainty work guys.. The worse part is going
to be the fuse with all its compound curves. MAybe I should hold
a sanding party..
Note about the kit: This is a first class kit. all parts cut (no
punch outs).. Includes all hardware. One thing I will not use is
the NYRODs. Will use piano wire instead. Will also install spoilers.
Plans detail an optional thermall sniffer.. I think I will bypass
that.. I've read that one can buy these widgets that will sense
thermal and feed input to the rudder. That way the pilot have visual
notification that the plane is in a climb.. Anyone got any comments
one these??

666.8 | Aquilla is not part of a sailboata! | MJBOOT::BENSON | __Frank Benson, DTN 348-2244__ | Tue Aug 23 1988 11:11 | 14 |
| MD-
It's about time you started that beast! It is a beautifully kitted
plane, isn't it? (I'm kinda sory I sold it, now :^} )
I think that the rudder/thermal sniffer is kind of hokey, it might
be difficult in knowing if the turn is trim or windvaning or thermal
sniffer related. Better you should watch the wings for turbulence/
lift indication and FLY LIKE A MAN!! (That's _like a person_ for
Dianne!) :^) :^)

666.9 | Another kind of sniffer | MURPHY::ANKER | Anker Berg-Sonne | Tue Aug 23 1988 11:39 | 18 |
| Re:< Note 666.8 by MJBOOT::BENSON "__Frank Benson, DTN 348-2244__" >
The thermal sniffers I know of don't affect any control
surfaces, but send a signal to a receiver on the ground. The
normal signal is a tome that goes up in pitch when the sailplane
is rising and goes down when in a downdraft. This leaves you in
complete control of the plane.

| Anker-
The transmitter type of sniffer is what's shown on the Aquilla plans;
those are the only kind I'd consider. Lately, however, I've seen
ads for a type that doen't transmit... when it senses lift it feed
right rudder to let you know; those would make me nervous!

666.11 | I Miss Spoilers | USRCV1::BLUMJ | | Wed Aug 24 1988 09:54 | 13 |
| Regarding Anker's comment about not missing spoilers, I can understand
that when flying a 2-meter ship(ie like his Metrick). The smaller
span, lighter wing loading ships slow up nicely when brought into
the wind, however the larger span ships are much more difficult
to bring down in a reasonable area at a reasonable speed without
spoilers. As the wing loading rises, so does the speed and the
ship seems to glide forever when you want to land. The spoilers
allow you to bleed off a lot of altitude quickly without dropping
the nose and raising the airspeed. I would not build a standard
class or larger ship without them, unless it was a fun fly ship
only and I hade a large field to land in.

666.13 | day 3 | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Thu Aug 25 1988 10:23 | 17 |
| Started work on the Fuselage.. This is not a slap'em together, sand
a bit & cover affair. No Sir !!. There are fairings all over the
place. And I won't even begin to tell about all the sanding i'm
going to have to do. Bootom line: This is one very sophisticated
flying machine..
I got the sides done (add triangle stock, mark for formers) Then
worked on the tail fin & rudder attachment. This a critical part
as the stab is a single piece and therfore the play must be just
right. I also have to make its square, otherwise the whole tailplane
will be out of whack..
Today I go out to get myself some glue & microballoons.. Also ne
fuel for the CUB..

666.14 | day 4 | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Fri Aug 26 1988 11:31 | 15 |
| Last nite was a slow one. Started by finishing the tail fin.. That required
epoxxy and making sure everything was lined up & square. Otherwise
things will real intersting when the fin is taatached to the fuse
and then the stab & rudder attached to all this..
Started fuse assembly. Attached fuse end (again epoxy so that I
could line things up.. Now with all my clamps iin use, I had to
wait a while.. So I trimmed the top fuse sheet and then sanded one
stab panel..spenn an hour on just that..came out real nice.. Need
a little filler where I gouged a bit.
This weekend is going a biggie: fuse assembly..Maybe start on wings.

666.15 | days 5-6-7 | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Mon Aug 29 1988 10:32 | 25 |
| The weekend was a bit slow..household chores sorta got in the way..
Anyway. I got the fuse boxed. It's as long as the one on my CUB.
Its also a lot skinnier. It came out right on the money as far as
lateral dimensions are concerned. The only prblem I have is a slight
twist..The instructions say that this is normal and correctable
when installing the fuse bottom.
I also install the rudder pushrod.. So now I'm ready to install
the tail fin.. This one is a bit tricky.. first you need your stab
& rudder 'cause you're going to put on the stab fairings. You also
are going to position the rudder. everything has to be square relative
to the fin (the instructione mention something about longitudanal
decalage.. That's the side to side stuff, right ??)
So I had to final sand the other stab half and the rudder. Tonite
I put the pieces together.
I'm going to have to build the wings next because at the point you
have to put the wings in to make that the tail assembly is square
with the wings (ie take out the twist)..

666.16 | SPELLING-BEE....?? | PNO::CASEYA | THE DESERT RAT (I-RC-AV8) | Mon Aug 29 1988 11:47 | 15 |
| Marc,
Correct! Longitudinal decolage* translates to built-in (desired)
offset in the vertical stab (fin) and/or, in the case of a power-plane,
right of left engine thrust.
* BTW, can anyone provide the correct spelling for "decolage?" My
Funk and Wagnalls doesn't contain the word and I've seen it spelled
so many different ways I'm really curious...gracias in advance.

"Decalage" is how I used to spell it 'til I saw it spelled dec"o"lage

to verify the correct spelling. Goes to show that the mag.'s aren't

666.19 | day 8 | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Tue Aug 30 1988 10:24 | 28 |
| last nite was diddle night. I finished sanding the rudder. That
was the easy part. I then proceeded to install it..Weelll, let me
tell you, this was fun..
First some background. The rudder is designed to be removable. Two
hinges are inserted in the tail fin. an other in the rudder. There
also a 1/8" OD tube in the rudder rib just above the fin. You line
everything and insert a 3/32" hinge pin. Aah,.. easier said than
done.
I positioned the brass tube per plan and discover that this would
require a 3/32" gap on the rudder hinge in order to make fit.
(the hinges on the tail fin are flush against the rudder post. So
I had to shift the tube back (enlarge hole, shim,etc) so that
everything is just right...
Of course, as you got through this exercise, you have to make sure
the lateral alignment over the fin is correct, that the rudder clear
the top of the fin and that the vertical alignment is also what
is supposed to be..
I quit after two hours 'cause I couldn't see straight anymore..
I think I still have to do some work on the vertical alignement..
md

666.20 | | SPKALI::THOMAS | | Tue Aug 30 1988 11:22 | 9 |
| An easier was is to employ a tape hinge on the rudder. For this
you bevel the rudder's leading edge all to one side like a barn
door aileron. After the vertical fin and the rudder are covered
you align the rudder to the fin and deflect the rudder. Run a strip
of tape on the outside and then deflect the rudder in the opposite
direction and add a second piecr of tape to the inside of the hinge
joint. Any vinyl tape can be use.

| re .-1: Naah.. Thats refered to as vertical decalage..and everybody knows
about that one...
Anyways, onwards with the daily report..
I had an other look at the rudder (with rested brain cells) and
noted that the "kink" in the rudder assembly was actually to the
the fin being twisted. SInce the fin is made of plywood sheet on
a frame of basla & spruce, I was a bit suprise.. So out with
the knife, unglue on side, shift a tad (like 1/32"), reglue aand
voila, one straigth rudder assembly..
I had to set aside the fuse in order to build the wings..They are
needed to ensure that all surface are square relatie to each other..
So, I cut the sheeting for wings.. there are 7 sheets of 1/16th
stuff to cut to various shapes. fine.. nice relaxing work..
Now to start the wing assembly...Get trailing edge...Hellllo, what
is this?? TE is a built affair made of 2 1/16th sheet separateg
by a 1/4 by 1/16th strip.. but wait, there is more. The bottom
part of the TE must beveled to zilch on the last 3/8th" to form
the airfoil...yeah sure...do that for 100" of strips.. Arumph
Ok so I sanded (by hand, guys, by hand!!) for more than an hour
and fgot the inner panel TE done. The outer panels I'll attend later.
I have to build the inner panel and ouoter pannel separately because
my work area is limited..
QUit at 12:30 'cause the next step is to start assembly.. I need
a rested mind for that. This wing assembly make the CUB's setup
look like a picnic..

The other inner panel has LE, TE and capstrips in place..
The next major step calls for putting a mixture of epoxy & microballons

is not mention of proportions.. I plan to use a 50-50 mix..

| An other slow weekend..I got started on the second inner panel
(capstrips & bottom spar glued when I notice a couple of things
didn't look right (like the spar was 1/16th off on the plan - now
I _know_ I measured the sucker just right. And the ply shear web
that sits near the wing root was also of by the same amount..)
Then I remembered about the the root rib being a ply rib..And that
the plan for the second wing probably was drawn to show it in place
(the first one does not)..So I lift the wing of the plan, and sure
enough.. the whole thing is offset to show the ply rib..
Grumble, arumph.. dismantle the capstrips, re-pin the wing correctly
and proceed on..
Took Saturday off..
Sunday, started on outer panels. spent the better part of the evening
cutting TE pieces to shape & sanding. Started on 1st outer panel..
Last night, watched PLATOON on HBO (Messy movie that !!)..Finisehd
outer panel and got far enough on the last one to be at point where
I glue ribs & spars.
Tonite, the fun begins. I get to glue wing hold down tube in place.
The we go on to gluieng the panels together with proper Dihedral.
BTW, does anyone know what "sanding hand-laucng glider style" means??
(In context here, when I get to the point where I have to sand the
ends (LE, TE & spars) of the inboard & outboard panels so they butt
properly, the instructions say to raise one end a certain amount and
then "sand the other "hand-launch glider style".

| I ran into a stone wall amd I'm not pleased. In fact, I'm rather
p****d off !!.. So last night, Im going to finish the last outer
wing panel(hey, real easy, just add ribs, spar & webs). Well I now
have this little problem: The last spruce spar in the kit ain't
what it's supposed to be..It's a 1/4" x 3/16"... it's suppoed to
be 1/4" by 1/8". Now there is one other place in the kit where I've
used this kind of wood and its in the fuse as a doubler. Check this
instructions, check the plan.. It sez use 1/4 x 1/8..So no mistake
there... I guess I have to go out and buy me a spar.. (i was temptd
to build me one fromt the left overs.. with the shear webs in place
its probaly not going to be a problem.
Ok, so pass on the outer panel.. Go and install wing joiner tubes..get
1/4" OD brass tube. That goes into wing...drill trough W1 .. fine..
Now get 7/32" joiner...I must presume this a steel rod. (all the
joiners are). I looked high & I looked low. I looked over and I looked
under.. I looked far and I looked close. Nada.. Nixt... A steel rod
this big and about 8"" long just does disappear that easily..
Now anyone got suggestions on where I can get such a piece..
Ass it stand, I can't do much more as the joiner is needed to allign
the tubes. Then I need to finish the wing in order to finish aligning
the tail feathers..
grumble. grumble. grumble

Is there some reason why you _can't_ use a piece of 7/32 music wire?
It'd certainly be more than strong enough! Is it possible the kit
intends for a piece of wire to be used and does _not_ include it in

| Marc,
You bet! Piano/music wire'd work just fine, provided it doesn'
require any exotic bending...I'm assuming the joiner is basically
a straight piece, perhaps with a slight bend to allow for dihedral.
Size is no particular problem; consider that yer' average landing
gear wire is 5/32: and the giant-scale guys frequently use 1/4"
and _bigger_. 7/32" is right in the middle somewhere and shouldn't
be difficult to find...I could go down to the local hobby emporium
and buy it right off the rack. You'll have to use a cut-off wheel
(like that made by Tuff-Grind) in a Dremel-tool to cut it though.

| re .-1: Ok, I'll look it up.. The comment was made to me to make

The piece I need is straight. Dihedral is taken care of by angling

them in place.

| MARC,
I'll bet the other joiners in the kit are nothing but music wire;
what'll ya' bet?
BTW, how far does the joiner in question project from the side of
the fuselage? It'd hafta' be _plenty_ long before there'd be any
potential for bending. If we're talking simply about short stubs,
about 3-4" or so long, I can't imagine enough flight load to bend
them; Hell, my scale oleo-struts on the MiG-3 are connected to the
retract units by being set-screwed to a 3/16" music/piano wire stub
and, despite being pranged pretty good a number of times, these
wire subs have _never_ even tried to bend!

666.34 | Heat Treating Wing Rods | USRCV1::BLUMJ | | Thu Sep 08 1988 16:50 | 17 |
| Although I tend to agree with Al, "How the hell could 7/32" music
wire bend without the wing ripping off", let me relay some info.
I read in a review of Ken Bates Merlin Glider carried in a 1980
edition of Model Aviation Magazine. The Merlyn(designed by Ken
Bates who is avery successful contest flyer and LSF level 5 pilot)
requires heat treated wing rods. Ken is so emphatic about this
requirement that he actually sold them for $5.00. For those not
familiar with the Merlyn, it is a 155" wingspan with 2100 sq. inches
of surface area. The finished ship ways approx. 10lbs. and is capable
of speeds in excess of 90MPH. Considering Ken's background and
achievements I would tend to trust his judgement. However, the
Aquilla is a much lighter ship and probably would not require heat
treating.

| Spent the weekend working on the wings. Talk about detail work..
first I set the joiner tubes with a mixture of expoxy & micro-ballons..
This mixture turn to the consistency of chewing gum.. Makes for
intersting results..
Then fit the outer panel dihedral set (right wing) and glued the
pieces together. This time (unlike my experience with the CUB, I
made sure everything was pined and straight..
Wath with the ply joiners, the capstrips and the sheeting, I spent
the better part of 4.5 hrs doing the one wing..
the second wing is in position and ready to get the same treatment
tonite.
Tere is a glider fun fly this week-end.. I'm going to try to make
it.. at this time it looks real tight.. The fuse requires a major
sanding job..

They're also having a glider contest. As I recall, it is supposed to be a 10

somebody explain the details of such an event? I'm planning on being there but
I'm apprehensive about entering since they probably will be using a winch, which
I've never used before, and considering Kays' wing-folding experience, I'm not
sure I have the nerve to try.

666.42 | day 20 | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Tue Sep 13 1988 10:22 | 15 |
| finished the other wing last night..
Now the fun begins: sanding & gouging. we start with the wing tips..The
AQUILLA as tips known as Hoerner tips (They flare up and cheat the
wung in thinking its actually longer than reality..). So you get
a block of wood, a scoop knife, left over core from MONOKOTE,
sandpaper and patience and go at it..
Oh yeah, there is also this mention to make the LE progressilvely
blunter along the outer wing panel in order to avoid/reduce tip stalling.
Now lemme see, tonite & tomorow on the wings. Thursday & Friday
on fuse... Saturday we cover...Its a long shot for the fun fly..

The AMA rules (which I have but have not read) have been quoted to me
several times. 10 minute precision is what we call thermal duration.
Usually 1 point is earned per second up to 10 minutes in this case.
After that 1 point is lost per second until the landing. The AMA rule
on the landing stop time is the moment of first contact of the craft
with anything other than air or another craft. In other words ground or
trees. The AMA rule on start time is the instance it drops off the
winch. There is usually a bonus score awarded for landings. Usually at
CMRCM they have a graduated tape that starts at 100 points for perfect
landings and a mark every 2 or 3 inches with a decreased score. The AMA
rule is that the landing is worth 0 if the craft flips over of sheds any
parts. They are trying to prevent Anker from dropping an anchor at the
landing target and also they want the landing to be realistic so wings
and canopies should not fall off.
>I'm apprehensive about entering since they probably will be using a winch, which
>I've never used before, and considering Kays' wing-folding experience, I'm not
>sure I have the nerve to try.
Go for it. I never harmed a glider on a winch unless I was greedy.
Ask an expert to launch it for you the first few times. Al you have to
do is steer and he will run the winch for you. They have always allowed
this in contests - don't know what the AMA says about it though. In N.Y.
there was a guy competing from a wheel chair so naturally somebody else
ran the winch for him. I personally never had anyone else do the winch
cause I wanted max exposure since I only get to use one at contests.
Disclaimer - above rules are based on my experience and listening to
other glider guiders at contests. The rules for launch and landings are
also specified by the LSF in another note. I have read and understand
them and they are as listed above. At pilots meetings just before the
first launch we always ask questions like what is the rule on
POP offs?
Tree landings?
Declaring landing zone targets?
etc.
For instance at some contests POP offs count unless in the opinion
of the winch operator or CD it was caused by faulty equipment. At some
contests you are allowed a fixed number (3) pop offs. At my last
contest you could have all the pop offs you wanted? So what is a pop
off you ask? That is when the winch (or high start) pops off the tow
hook way before you want - typically 30-50 feet out. Usually it is
caused by greed - too much up elevator. You can also cause it by
too long a pause between pulsing the winch foot switch thereby causing
slack in the line. Equipment can cause it by line breaks or if there
is a parachute on the line it could open and you over fly it if it is
very windy and you have a lot of down elevator, retrieval lines can
pull it off if they are snagging on the ground, etc.
The tree landing issue came us because we had so many tree landings at
the CRRC meet. The rule there was you got a zero for the flight time
if you landed in a tree. Sort of infinite penalty points because you
went over time and haven't landed yet. The rule on the last contest
was if you could see the plane the time stopped when you hit the tree
(landed).
In the New York contest they had two close landing zones and you had
to declare which one was your target. One guy over shot and made a
great landing at the wrong target. Half of us thought he should get
the landing - the CD said NO. At the last contest they also had
two landing zones and allowed you to declare seconds before touchdown.
The wind sort of helped us decide where to land.
Go for the contest Dave - you'll love it.
In case anybody saw it but didn't make the connection - Dave's glider
was at the last fun fly. It was the Sophisticated Lady with the authentic
American Indian design Ultracote job in tan and brown - beautifully done.

| I have been following your progress, but have not seen anything
about spoilers. Did you put them in? If so what type did you use.

Remember - this is for CMRCM members only as per note .40
I'm sure they welcome spectators.
It would be at the same location as the DECRCM fun fly.
Most events start around 9:00-10:00 AM so 9:00 is a safe time to
arrive for nearly anything you are not sure about.

666.48 | Spoilers ?? You bet | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Tue Sep 13 1988 15:01 | 8 |
| re .-2 or so about spoilers..There will be spoilers, per plan. Which
means its a preformed TE piece set so that it flush with top of wing.
They are pull up type with a weight to pull them back in place.
I plan to link the servo to the throttle channel.

| well things went a lot better than anticipated.. I got both wing
tips done last night..It's amazing how damage 50 grit sandpaper
will do to basla.... Also it was a lot easier to carve the tips...
I even managed to get the LE of one wing done..
Tonite its spoilers and do the other LE. Then onto the fuse..

| SLow nite again..
Turns out that setting spoilers in their bay took a lot longer than
anticipated just to make sure they were flush with the wing.
Then I moved on to the fuse. I permanently set the fin in position..
The rudder pushrod was installed and epoxied in place.

666.53 | Is the Aquilla Dead? | USRCV1::BLUMJ | | Wed Oct 19 1988 12:29 | 9 |
| Is the Aquilla project dead or what? I have not seen an update
for over a month. Getting married and being in the process of buying
a house has brought my Algebra project to a screaming halt! Went
flying last weekend and had a 1/2 hour flight with my Sagitta 600.
I'm hoping for good weather this fall to extend the flying.
Regards,
Jim

666.54 | Nope | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Thu Oct 20 1988 10:31 | 11 |
| Gee, funny you should mention it !!..
No its not dead. It got put on hold due to family and work pressures
I recall alos the Olymics getting in the way.
I got back to it last night. The tail fairings are glued.
I'm at the point where the cokpit is getting built and the wing
fairings installed. After that, its sanding time.

666.55 | Aquilla Status? | USRCV1::BLUMJ | | Wed May 03 1989 09:32 | 10 |
| Marc,
Has the Eagle taken to the air or is it still wallowing on the bench
like my Algebra? Funny how these things always take a hell of a
lot longer to build than you originally estimate. Let's hear how
its going.
Regards,
Jim

666.56 | Only a few more days. I promise !! | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Mon Oct 16 1989 11:13 | 47 |
| OKOKOKOK.. So I've Been out for a while. Work has been crazy. Home has
been crazy and money has been tight.
Anyway, I have progress to report. I left off this tale where the fuse
was just about complete and ready to get sanded.
Threee week ago, I pick things up again. Got the fuse sanded. FUN!!
Dust all over the place. Sucker came out looking pretty good. Was a
lot easier than anticipated. Nice curves !
Built & fitted canopy. Snug as a glove.
Then came the moment of truth. Covering. To paint or to MONOKOTE. The
book suggested the fuse be spray painted 'cause of the curves.
Well I don't have equipment. I don't have the space. And I'm a complete
klutz with a spayer. MY consultant sez use a brush.. HUmmmm. Maybe.
He also sez: I can over this cover this sucker with two pieces of monokote.
I have 4 rolls of the stuff (came with the kit). SOLD.
WELLLLLLL. This was fun and a lot easier. MONOKOTE will stretch ever
which way. Two evenings & I'm done.
Wings & tail feather a breeze.
Fit everything together. Tail is square. Wings in line with tail.
A little heavy on the right. No big deal.
Spent weekend fitting electronics. Had to gut the CUB. Talk about tight
fit. The servos are a little deep and a little wide. Trim mounting rails.
YUK.. Everything OK.. Front servo is just even with canopy edge. Had
to trim canopy floor for fit. Fortunately, I have 1/8" to play with.
Onto spoiler adjustement and balancing this week.
I have to repackage battery pack. Its a flat style. Has to be square
style. I plan to clip a tab, solder a wire in its place and fold the
batteries together.
Maiden flight sometime this week, weather permitting.
All in all, this is a fun plane to build. Learned a lot and the results
look pretty good so far. I hope the plane flies as good as it looks.
Now for an encore, I think I will try an ORCA (Model Aviation, October
89 - or is it November). Same base technology with a few (sic) twists.

weather.

666.58 | It flies !!! | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Mon Oct 23 1989 17:38 | 18 |
| Went out Saturday. A bit breezy. found servos reversed. fix using
switch in Tx.
A few tosses to check attitude. best way to describe flight is
"majestic". All ok so hook up on hi-start.
Tow up is just fine. release. Aquila then gave a real runn for the
money, porpoising like crazy. Also found difficult to turn.
FInnaly got it under control and back on the ground in one piece.
Discovered pushrods were flexing and not providing control needed. Take
home & adjust.
Switched to Gentle Lady. Got a couple of more fligths in and called a
day (geting cold). will try again this week.

666.59 | trim is perfect | BZERKR::DUFRESNE | VAXKLR - You make'em, I break'em | Thu Oct 26 1989 11:23 | 17 |
| Went out yesterday aft. Perfect day to fly & trim out the glider.
little or no wind. Bright sunshine. About 70 deg.
Did a couple of hand tosses to check for gross imbalances. Couln't find
anything.. SO we hitched the sucker on the hi-start and let let rip.
Up staight as a arrow. very stable. Off the hook and check for trim.
Weellll. It turns out we needed nothing. a case of "it flies right of
the box". Very nice.
So Ispent the next few hours going up & coming down Longest flight was
about 5 mins. Not bad, considering this was really the first time i've
flown solo.
Weekend looks promissing..
