I was flying my foamy yesterday, and when I did a low pass in front of the flight line, I got some severe glitches... a buddy of mine was next to me with an illegally retuned TX. Was it his TX, or was it my crappy feather RX, or a combination of both... I'll never know for sure! I do know that when I flew without him next to me with his TX, it flew fine! When I landed it, an severe aileron glitch hit, flip it sideways, and snapped my stick fuse on the foamy... nothing an hour and $2 worth of materials can't fix, but I'd hate to cause more severe damage to someone else's plane because I was too cheap to retune my radio properly...
