On my aerial photo helicopters:

Zenoah ignition gets into my digital camera.
It has ruined a couple of PPM receivers.
It even gets into the shutter servo.

Zenoah does not seem to have any provisions for reducing this emitted bad energy(or whatever).

No body complains about the effects of spark ignition on their electronics.

Is it just me???

Can it be totally suppressed??

Any other method than using shielded plug cables and "R" rated plugs??

Cheers.

Try the best you can to keep any radio wiring or gear at least 6 inches (more would be better) from the coil, magneto or plug wiring and plug. This generally will do. If your plug is old and dirty, it will break down and cause RF from this.
You can also install on any affected servo lead back to the reciever, a ferrite coil or "choke" that will keep the RF from popping your radio. These can be purchased from electric RC suppliers and from Horizon.

Also, DO NOT run a full length reciever antenna on your helicopter with a gas engine, use a Deans or Revolution whip loaded antenna.


Hope this helps!

Try a new coil

With the suppressor cap you are only masking the problem, go to the root and change the coil. www.davesmotors.com

Good luck
