Please help! I have a 27% Cap 232 with a 60 ZDZ and I am getting radio interference. When I turn the switch on for the ignition my servos start jumping. All of the engine accessories are mounted in front of the firewall. (ignition module, switch and battery) And my servos are on the opposite side of the firewall, also there are no metal control rods for the throttle or choke. They are plastic nyrods.

Please help!!!!!!!!!

get your throttle servo as far away from the engine as possible. I like to go at least 15 to 20 inchs away and don't have trouble. Having your throttle servo right behind the fire wall is almost as bad as putting your rx up there. Also use a resister plug if your aren't already. Keep anything connected to your rx as far away as possible ( on-off switch, batt., servos, ect.). Hope it goes well for you.

Or you can use the Fiber Optic servo extensions with the throttle servo right with the engine which isolates everything from the reciever. Here is what I mean. With this, you even power this servo with the ignition battery.
