Was at the field yesterday and when I powered up my Tiger 2, got servos glitching. Not real bad but noticeable. Started engine anyways and gave it full throttle. Backed down throttle on the tx but, the engine was stuck on full throttle. Luckily, we use those plane stands at the field. Didn't have any servo control either as the FMA rx wouldn't accept any input. Shut engine down by pulling fuel tube out from needle valve. Took the wing off and moved the rx away from the servos. I also noticed that I had my cell phone on in its holder which clips to your pocket or belt. I shut it off and put it in the truck. After putting the wing back on I turned on planes system and didn't notice any glitching. Flew the plane for 5 flights without nary a problem. So, would having a cell phone on within a few feet of your tx and rx cause radio problems? I use a Futaba 9C transmitter and hitec/futaba/fma rx's. When I was getting no input from the rx the first time, it was like someone else on your channel. But it couldn't have been that because I was the only one at the field.
