Harvard tip stall
#1
Thread Starter

Just finished test glides on a .10 powered Harvard/AT-6
WHAT a nasty tip stall!
The CG is ok
Has washout in wingtips.
The stabilizer incidence is zero degrees
The wing is plus 2 degrees
No ailerons, rudder and elevator only
I've had a free flight Harvard that was quite tame.
Maybe I have the elevator set too touchy?

Yup. The elevator is too touchy!
The T-6 is a horrible airplane, no matter how you look at it!
The full-scale was bad, models are just as bad.
Move the c.g. forward a bit, and cut down the elevator travel.

There's an old saying about the T-6 Texan. It's not safely landed until it is tied down on the ramp. I have built a couple of T-6's, and all of them have went to the giant hanger in the sky. Tame down the elevator and use some expo on it, if you can.

Thanks everyone--I also cut down the weight by clawing a bunch of wood out of the airplane,
and removed the muffler from the OS .10
It should have a realistic cackle now!
Will post pictures in the 1/2 A Forum in a month or so
-that is, if it decides to fly!
