RE: Eletronic engine syncronizer **SUPPORT **
Jason,
If I understand everything you are saying correctly it sounds like in summary the following is happening:
Everything works like normal but sometimes engines go to idle. Engines go to idle if you get a receiver fail safe/loss of transmitter signal. You do not have to go to idle to regain control with receiver fail safe. If it were losing a sensor you would have to go to idle to regain control. You would see similar symptoms with a faulty sensor/sensor install issue but having to move the stick back to idle would be required.
If I recall you have glow motors. So it is odd you are seeing this. What is the make and model # of your transmitter and receiver (Hitec RCD-3500 receiver by chance)?
Sounds like we should talk again.
