Default weedwhacker interference

I was helping my neighbor build an rc boat with a weedeater engine in it. (homelite engine) On the first test run of the engine the ignition interfered with the radio. It was an FM radio and when the engine started the boat went into full throttle and started slamming around the rudder. fortunitly it was on land so we could shut off the engine. We tryed it with another FM 72 radio and the same story. talking to some other people they said 2.4 would not work eyther. We are bolth experienced builders but have never experienced this before. my idea was to wrap the engine in brass screen to hopefully stop the interference but i would like some imput

Check the spark plug, you want a "R" plug, R for resistor.

Interference at the levels generated by an ignition system might well not be getting into the RC via the aerial.  If the interfering signal is big enough, the servo wiring will pick it up and present it to the electronic bits via the battery power wires.  The semiconductors will then detect and amplify it, and cause all sorts of servo reactions, just as described.<div>Do as W3BBY says.</div>

we have had to wrap the ecu's in industrial forklifts on the tier 3 fuel systems because they werent shielded inside and the coil was interfering with it. we wrapped them with aluminum foil and it worked. i have also run into servo glitching on my helo's because the rx was to close to the esc.

It must have been a Yale, those over-engineered pieces of junk.
