Thanks, but I just retired my Hitec Feather RX (cheap, single conversion RX) to my spare parts bin, and installed a Hitec Electron 6 (good quality dual conversion micro RX) in my foamy... I doubt I'll have any more problems now. I've flown several different dual conversion RXs (including Electron 6 RXs) with that same guy & his "illegal" TX, and never had a problem. I've also ordered two more Electron 6 RXs for my other two foamies that are under construction. I'm not going to cheap out on RXs any more, not even for foamies...
