Thank you so much for your reply. Now I must show my ignorance about a few things.

#4. The engine runs great. Could the glow plug still be bad? If so, could it cause a signal loss problem?

#6. How can I tell if I have a bad engine bearing? The engine seems to run fine.

My receiver is a Futaba FP-R129DP

#7. Where is my receiver crystal? There is a small aluminum looking thing in the bottom of the receiver. It has a sticker on it with writing on it. The unit seems sealed with 2 small screws in the bottom.

#8. Where is the receiver power switch? I don’t see one on the unit.

I will do the other suggestions. Thanks again……jster
