Here is the latest.

I changed the glow plug but as soon as the engine started, I lost sighal again. Then I connected the receiver battery directly to the receiver and had the same problem. So.. I ruled out the glow plug and the switch.

I restarted the engine and pulled the remote glow plug adapter off the glow plug and got the signal back again. I had the signal for a minute or so, and then it glitched (the servos hesitated for a few seconds, then started working again).

The weird thing is when I pulled the remote off the glow plug and the signal came back, I tried putting it back on, and it continued to work as if it were off (it glitched a few times a minute). The remote glow plug adapter has a ground to the engine and the other to the glow plug.

I then pulled out the crystal and put it back in. It was tight. Am I missing something in my home trouble shooting? Does the remote glow plug adapter pulled off give another clue? Please let me know if does. I want to go buy things tomorrow. If I need a new crystal or remote glow plug adapter, I want to get everything at the same time.

Thanks again........jster
