| I saw one of these for the first time Sunday morning during our
beginners time... Sorry, I can't remember the name of it.
Mike flew it and even in the wind he was fairly impressed with it.
He said that it handled quite well. The only thing was that it took
quite a bit of down trim, if I remember right.
FWIW - This (now) poor guy bought the whole setup at Eric Fuch's
Hobbies (the "hobby" store chain located in many malls around here).
I didn't dare ask what he paid for it, but I suggested that there are
other alternatives...
cheers,
jeff

| Sounds like the CG may be much to far aft.

| I thought this, too. Several of us balanced it on the (virtual) spar,
and this not seem to be the case. Admittedly, the absence of a
physical spar could be a source of error, as we had to guess where the
CG would be. He bought it used with no instructions.
He claimed it flew and flew well where he brought it from.

| If he bought it without an engine then the right and down thrust might be
screwed up. The roll might have been due to torque

| 1611.5 | aircore... | GALVIA::ECULLEN | It will never fly, Wright ! | Tue Jun 28 1994 11:05 | 6 |
| Probably not but it sounds similar to the AirCore kits, made of
corrigated (?sp) plastic. One of our club members has one. Flys well
and is indestructible. You basically fold the pieces together and viola
one airplane.

| Does it have a covered wing?
My father had a plane which acted like that. Looked fine, balanced
fine, nice hand toss behavior but at speed it was a mess. Turned out
that the monocoat had separated at the leading edge from one of the
wing panels, and at speed would lift and mess up the airfoil...

| 1611.7 | our conclusions | CSC32::HAGERTY | Veni, Vedi, $Cmkrnli, Rebooti | Wed Jun 29 1994 09:48 | 12 |
| It was a one-piece wing of a sort of hard plastic. When it did the
ground roll, it just scraped up the v-stab a bit. Not a stick of balsa
or ply in it that I could discern.
We talked about it again and came to the conclusion that it must be one
or a combination of the following:
a) major league left thrust (a joy on takeoff)
b) warp 1, Mr Scott
c) flawed design to begin with

| 1611.8 | | VMSSPT::FRIEDRICHS | I'd rather be flying! | Wed Jun 29 1994 09:57 | 9 |
| Sorry, it can't be (c) as the guy that brought this plane out had
no experience on how to build. So, if we are talking about the same
plane (and I believe we are), the design isn't bad. I will try
to get some more info about engine size, see if there is any thrust
built in or what...

| 1611.9 | A few more checks won't hurt | MKOTS3::MARRONE | | Thu Jun 30 1994 13:39 | 20 |
| A couple of thoughts.
Check out the lateral balance. It won't fly well it one wing is
heavier.
Despite the "apparent" good CG, I'd move it further forward to see if
anything changes for the better.
Put an incidence meter on the wings to check for warp and for wash-in.
Either one will cause a problem, and I've learned NOT to rely on eyeball
checks to determine if warp is present.
General Comment: I have never seen a plastic model that flew as well
as a balsa/ply built up model. Period. I don't know the reason why,
but they just don't fly consistently well, and some days they are not
bad, other days the same plane is unflyable. The one exception I've
seen is one of the Kyosho ARFs which could be favorably compared to a
built-up.

| Garbage up - Garbage down!.
I have seen one of these planes before. I think that Charlie Watt test
flew it. It was too heavy.
End of story.

| 1611.11 | Yep, he right | MKOTS3::MARRONE | | Thu Jun 30 1994 14:17 | 6 |
| Eric, you have such a way with words!!
But these are my sentiments, exactly. I was just trying to be more
diplomatic.

| 1611.12 | I Agree | LEDS::WATT | | Mon Jul 11 1994 13:48 | 7 |
| Small heavy Cubs fly like SH$T. I had a beginner show up with one that
took all of my experience to fly. Needless to say, he didn't get much
stick time and I'm sure he quit the hobby before ever getting a chance
to enjoy it.

| 1611.13 | The end of the story | CSC32::HAGERTY | Veni, Vedi, $Cmkrnli, Rebooti | Tue Jul 12 1994 09:38 | 5 |
| Well, this story has a happy ending. The guy *did* eventually commit
the cub to the dustbin and bought a "regular" trainer. I took it up and
it flew much more sanely. He had quite a bit of time on it the
other day when he bent it a bit on takeoff. He's in the course of
fixing it. In other words, things are quite normal :-).

| 1611.14 | Nice to hear. | CSTEAM::HENDERSON | Competition is Fun: Dtn 297-6180, MRO4 | Tue Jul 12 1994 09:42 | 5 |
| That is good news. It grieves me when I see guys get the wrong start. I
think that clubs should write a "Primer" and leave it in all local
model shops.

| 1611.15 | Right Start | LEDS::WATT | | Tue Jul 12 1994 14:00 | 10 |
| The best advice I could give anyone is to join a club BEFORE
they buy any RC stuff. I was lucky that I had a buddy that gave me
good advice before I bought anything. (he also taught me to fly) Bill
Lewis saved me much grief and got me started with the right equipment.
It's a shame when someone gets interested in the hobby and gets
started off on the wrong foot. Many will give up and never get the
chance to enjoy RC flying.
