Hitec Fusion 9 receiver...
I recently bought a new fusion 9 receiver. It's installed in a World Models GS Zero. Engine is a Zenoah G-38. The receiver glitches at full throttle. I've checked, and had the plane checked, for any possible radio interference issues. We did find a loose muffler on the engine and fixed that, and the glitching problem got better, but it's still there. The problem only occurs at full throttle with the antenna fully retracted, and more than 30 or so feet from the plane. Extend the antenna, problem goes away. The receiver has fail safe programmed, but it's not going into failsafe. It will enter failsafe with the transmitter turned off, but not when the engine is running. I haven't ruled out other possibilities, I.E switch failing or battery, but since the glitching stops when the antenna is extended, and only occurs at full throttle, I really tend to think it's radio interference.
Any ideas would be greatly appreciated...
I know it's customary to install a PCM receiver in gas airplanes, but I want to figure this out first.
Thanks,
Andy
