Justpoet,

Thanks for the reply. The ESC doesn't not start the arming process. There is no sign of life. That is why I first thought it was the power switch.
I opened up the case and the wires all look fine, and I could not see any damage at all.
1. I was only starting the count down timer on the radio. Not much of a change.
2. just coasted to a stop so I could simulate a 4 min qualifier. I had only done 2 warm up laps so It was not overheating.
3. & 4.No output from the BEC.
I did an update to V 254 from 250 and it said that the update was successful.

The only thing I noted was that the fan connector can be used to link with Hotwire but the receiver connector will not.
