I've lately been seeing pictures of and reading that throttle servos are being installed very close (even on the firewall) to the engine. I had always understood that this was a major no-no. Has something changed? Thought all the RC onboard electronics was supposed to be as far away from the engine and componets as possible to prevent interference. Is this possible with good shielding or by using two receivers or just luck? Have had some planes where I would have liked the throttle servo close to the engine but I took the stay away routine as gospel. Whats up with these servos just a few inches from the gasoline engine?
