I can't speak electronics talk but can tell about an experience at the club field. The guy had an Evolution 15 engine on a 4 Star 60 with a Spectrum radio. When the engine was started, the servos starting jittering especially the throttle. After the engine was shut down we discovered that the plug wire was over the plug but not turned and locked. I pushed the plug wire further down on the plug and turned it 1/8 of a turn to lock it on. The problem went away. My conclusion - - - it is possible for an electron ignition to mess up the operation of a 2.4 radio.
