Rickie...
Save all your money and try to fly with Kagan, Kang, Sanborn, Romash, Gowen
and all those other guys you read on this thread. You will learn more in
one session with those guys than months trading emails.
The are courteous enough to show up in Colorado to fly and I am still
amazed.

I am a fairly new indoor flier and have designed and built a pennyplane
from the "best" information I could assemble. Pictures posted in folder "
Richards Pennyplane". It weighs 3.2 grams (with prop), and all other details
are basic per AMA rules. I am using a balsa sheet, 15" dia., 25" pitch
propeller. (It weighs 1.2 grams.) - and 3/32 in. "A to Z" (Peck Polymers)
Supersport rubber from my hobby-shop. Rubber lube is STP "Son of a Gun", and
seems to work very nicely.
The wing is simplex 4%, and the stab is circular 3%. Thrust is zero-zero,
stab is at zero, and the wing, 4.4 deg.
I set up the plane using the "ten step adjustment process", and it flys
"right on the verge" of a stall. It reliably recovers from a rafter beam
"hit". The flight balance location is 88% wing chord.(With prop and rubber.)
It flies in approx. 14 foot circle and the climb is just beautiful to see,
flying very slowly at about 15 degrees attack angle. With the climb
loading the prop, it turns quite slowly, ...estimate 1.2 to 1.5 rev. per second.
Right now I am using a 1/2 length motor with weighted spacer, and winding
to 0.5 ounce-inch torque, I am getting lovely flights in a 25 foot ceiling
- 2 1/2 to 3 minutes. But I would believe the cruise period is very
short. The motor has roughly 1/2 length of "knots" at landing. If I put in more
turns the climb is too high, and with a longer motor, the flight is longer,
but of variable heights, with the causes unknown to me.
I would very much like to achieve a longer cruise time and and with slower
descent. Is there anyone with experience to suggest the next logical step
to me to take?
