I am having a heck of a time with an electronic ignition gas engine. I have the 2.4 Spectrum that will not work with this engine. I have one of the RVSC 26 engines from TroyBuilt models. The radio is rock solid as long as the engine is not running. I have read the 2.4 does not suffer from RF interference. I sent my radio to Horizon thinking it is a radio problem. They replaced the transmitter and receiver. I reinstalled the receiver and went to the field today. I charged up and did a range check. When I began flipping the motor, the servos all went hard over and were unresponsive. The LED in the receiver was flashing very fast. I cycled the flight pack battery switch off then on and the receive rebound to the transmitter. Again as I flipped the engine the radio went hard over. Thinking maybe the flight pack switch had failed, I connected the battery straight to the receiver. Same results. Next I tested my theory. I rebound the receiver with the ignition battery switch off. With the radio responding normally, I turned on the ignition switch and checked the radio. It worked fine. Then I pulled the prop through slowly and as soon as the magnet on the prop shaft passed under the ignition pickup sensor, the servos glitched! This happened every time I pulled the prop through. The receiver is well over 12 inches from the ignition module.
I am at a loss of what to do.
