Agree find the problem first. Make sure you receiver and antenna are far as you can get from the ignition. Second check the servos distances from the engine keep them as far away as possible..................... I installed a throttle servo to close and it gave me interference off the ignition. I put a choke on the TH servo and it cleared up the problem.

These are the ones I used but you can get them at any electronics supply house or radio Shack ect.......a lot cheaper. Put it close to the receiver and rap at lease 3 loops of the servo lead......directions will explain.........you might have to use servo extension to get you min 3 loops use more loops if you have the length.

After install on my G26 H9 ultra stick lite, I got the JR min of a 150ft antenna down engine running no glitches, now going to a PCM system after finding the problem will give me a much safer system than a PCM without the chokes.
