interference suppressors on electric motoers
HI Chris
Welcome to the site.
I use 0.1mfd caps across the terminals and from each terminal to the metal case. I have used 0.022mfd across the terminals but the 0.1mfd work OK.
Some motors have internal caps fitted, you can usually spot these through the case slots by the brushes. Adding more will increase the value and may make matters worse.
The main culprits are the heavy current fast brushed motors but all brushed motors generate interference. Brushless motors do not and must not have capacitors added to their leads.
Keep all dirty (high current) wiring well away from the aerial, rx and servos and try and route servo leads as far away as possible from the power (battery) wires.
I usually route the different wires on opposite sides of the boat.
2.4Ghz is relatively interference free but high current dirty motors should be suppressed to prevent interference. The Rx might be 2.4Ghz but the electronics in the ESC are still susceptible to high levels of electronic noise so keep the wires well apart and fit caps.
Our All Things RC section has some suggestions.

Although I am anything but new, I am new to model boats. Can someone let me know the correct size of the capacitors that need to be fitted to electric motors. I have been looking this up on on the web and am finding conflicting answers. Some sources even advise 2 different values on each motor, depending on where they are connected. I know that in these days of 2.4Ghz radios interference is not supposed to be much of a problem, but I would still like to know the answer. So Michael Faraday, where are you?
