Dafid;
You are right about the Neiuport, wing problems. I didn't like that plane either. I also tried the Jenny at least the wing didn't
collapse. Piperbig isn't much either I just tried it and you are right about that wing too. That piperbig wing is funny, If you taxi it away from you and oscillate the elevator up and down you can see the wing flap. Doesn't have much for landing gear either.
I suppose if we flew the piperbig the way it is designed to fly it would be fine.....But that ain't no fun.
The Piper J3 on page 21 RC-SIM is good.
