Problems In Radio HELP PLEASE Urgent

Hi guys
I need your help ...
I buy a new radio 2.4 it works already in a boat 26cc.
In my second boat I achieve another receiver that i bind and it works propely.
Problem with the 1 receiver and 2 receiver when the engine starts blocks no working either rudder or trotlle.
Pack batteries full ok
Servos working without problem
The problem just apears when engine start
Anyone had similar problem???

Many thanks

Hi. I am not at all an expert in this.
But I remember reading a thread about this issue, and it seems that you maybe need to get a special kind of sparkplug, that is insulated to prevent disturbances on radio signals.
Maybe Scott or Marc will jump in and help you.

Cheers!

Not knowing engine your using ? .... but YES R/C gas engine powered models MUST HAVE a resistor type spark plug fitted. The RF scatter interferes with the radio signals and will indeed create reception issues.

Hi Scott
It Hapens in my Billet not in RCMK .
The spark plug its a ngk WITH R.

Hi Scott.

Can you recommend some makes of resistor spark plugs to look for, and maybe where to find them?
I am very much interested in getting one (and couple extra) for my own engine (40 cc Blata).

Cheers!

Make sure receiver is AS FAR AWAY from engines plug and wire as possible, Throttle linkage is on nylon ends that won't transfer electric current/RF from engines cases.
NO CARBON FIBER push rods at engine end or CF box lids. Lastly try a fresh plug making sure resistor within plug is not faulty.

That's all the help I got :blink:

Take plug # you have and google search manufacturer, within that plugs family of like types/heat range you should find one with a resistor by seeing I.D. match plug you have with one having an R in the I.D. code. Use a cross reference to another MFG if required.
Most broad choices will be NGK or Bosch

Thanks Scott.

You are allways good for usefull advices.
"R" in the code should mean "Resistor"? I will check my current spark plug and try to find a couple more of the right sort.

Cheers!

Maybe a bad ground .......... hard to beat what Scott has said so far

Try switching the receivers to see if the problem travels with the receiver or stays with the boat. If the problem travels with the receiver then I would say you have a receiver problem.
