What about this Ace. One of my buddies had the ignition switch and receiver switch side by side with a few inches of wire from each running parallel and close to each other. During the ground test his servos would twitch every now and then. After I kicked him in the *ss he went home and arranged his installation the “right” way. He had no problems after that. Another guy had his receiver regulator and ignition regulator side by side with the wires also parallel and this time tied together. It worked for a while but the day I was there his system went into fail safe and then the ground. As we collected the pieces he explained to me what he had done and felt that it was all right since it had worked for some time. Dan.
