Ernest',
Is it possible for a chain-drive to produce interference with a radio? Sure, it's possible. Any intermitant metal to metal contact can produce noise, both the kind you hear and the kind your receiver hears. While it's possible, it's also very unlikely that your receiver will be affected by the chain-drive. Even if it is, it's not difficult to 'cure'. Just ground the drive system to the motor's case (same as the caps used for motor supression are).

doc, what do you actually means by "ground the drive system to the motor's case".
well that gives life to the idea, i think i will push through this system. would mounting the radio equipment as far as possible also helps?

'Grounding' to the motor case just means to make an electrical connection between the chain drive (mounting bracket, maybe?) and the motor's case. Distance between the drive system and the receiver will make some difference also, but I've no idea how much, can't hurt though. It also helps to segregate the 'kinds' of wiring, power(motor), signal(servos), and RF (receiver), if possible.
'Probability' and 'possibility' are not always the same, so if I wanted to use a chain-drive I'd certainly do so. Then, if I had problems I'd cuss it a while (and the idiot that gave me the advice) and then 'fix' the problem - LOL.

My Feedback: (1)

You just know that I've got to ask and wonder why someone else hasn't yet but what are you doing with the BMX chain drive? You're talkng some big gears there. I'm into bikes a little, I have a recumbent and my kid has bikes all over the backyard that people toss out during junk pick-up.
Smitty, you can't do it but Futaba or their service center can. They have to be retuned and it probably isn't cheap. You might be better off buying a 4-channel radio system that is already set up for ground frequencies.
