I have two FA2's with sound onboard. I have been trying to get the sound to time out and have had no luck. I read the manual and set cv 113 to 120 but once you acquire the engine and move the throttle the sound comes on but will not go off again unless you tip the engine to cut the power.  Does anyone have any ideas ?
Thanks Al

Help I had the red wire for the rear light come off the circut board and I do not know where to solder it back on.
