View Full Version : Shorted FETs?

2007.09.18, 06:27 PM
I was running my F1 when it suddenly stopped stopped running. The steering still works but no throttle. When i turned it off the motor started running. I'm thinking that I might have fried the FETs. Any ideas? Thanks

Sounds about right to me... (sorry to say :( ) Doubt much else would cause the running motor scenario when power is off.

Open it up and look for a tiny blister on top of one of the rear fets. Easy to do on an f1, just lift the body off and remove the antenna mount.

I'll do that. Thanks!
