I agree with Frank. I have micro switches attached directly to servos for my RC warship and for the RC tank and have no noise problems at all. In both setups, the receiver is in a small box next to the servos and micro switches. However, I do put caps on all motors, put diodes on all solenoids, and use diodes to drop the 6V battery to 5V for the receiver and have a cap on the receiver effectively isolating it from battery line noise. Bill P.S. Occasionally an enemy warship captain wanders in range of my guns before a battle, and a radio glitch fires a BB into their ship accidentaly. The "radio glitches" are common before a battle, so don't wander there! They seem to be in proportion to how much the enemy captain pissed you off earlier in the day.
