I used the matchbox on elevator(s), and had +/- 100 flights with my jet. The matchbox died on the second flight of the day, first flight was 100% normal. I always yank the sticks as I taxi out, something I have done since I began this hobby some 30 years ago, and elevators was alive and kicking. When I start the take off run, the jet (Mig-15) takes off by itself when the speed is right, and this take off was just like that. I tried to pitch down slightly, to build up more speed, but the Mig just wouldn't respond. I killed the turbine, and went for a extended center line "emergency" landing. I managed to keep the wings level (never stop flying the airplane), so except for the l/g being ripped out, the Mig was "intact".
Back at the depot, we started investigating why the elevator (both) was dead. Everything else worked 100%. When we disconnected the matchbox, both elevators came back to life. My matchbox was mounted approx 4 inches from the rx.
