Default radio interference

will i get into any trouble if the battery to my c&h ignition is less than 12 inches away from my radio gear? i need it far back for balance. i can get my receiver 10 to 12 inches away but the servo`s will be 4 to 6 inches away. the battery & switch for my smoke system are close too. thank you ,

This is merely my OPINION based upon lots of reading, but anything less than 10 inches of electrical seperation is taking a big risk (Futaba says min 12"). That includes the servos.

If you don't have any other choice, you can proceed as planned, then do a VERY thourough range check from all directions with the engine off (Futaba recommends min 100' w/ antenna collapsed), then test again with the engine running (all throttle positions). With the engine running, you should have no more than 10% reduction (Futaba's suggested cutoff) in range. If your range reduces by more than 10% you'll have to find some way to shield your electronics from the RF noise from the ignition.
