Andy, what kind of stunts are you doing with the Aerobird Challenger that you are collapsing wings? I presume you are flying in Pro mode. I have never folded a good wing on my Aerbird. I folded wings in the air, but they were damaged wings that I had tried to save.

We now have 5 Aerobirds in our club and I am not aware of anyone folding a good wing in the air. One guy is wild with his and HE hasn't folded any wings. Believe me, I would know. From the time he launches till he lands that plane is in constant turns, rolls, stalls, loops and he even gets it inverted for short periods. Oh, and he does all of this at full throttle at 50'. He doen't seem to like to get too high.

Certainly the Aerobird Challenger is highly aerobatic for a three channel park flyer, but I have never seen one fold a good wing. You must have some wild stunts figured out.

Tell! Tell!
