Aerobird Challenger Barrel Rolls
Is it humanly possible to do a roll in an Aerobird Challenger? My friend has tried several times, one time resulting in a folded wing. I read somewhere that you could do a roll by diving down to gain speed, then pull up and turn at the same time. I tried this and it always results in a sort of hammerhead stall/ channdel.
One more thing. Would it be wise to buy a new wing to not run the risk of my stock wing folding? I have about 25 flights on the stock wing and the wing has a few "beauty marks" but nothing to serious.
