Hi Nick,

Did you ever figure this out? How old is it? (The 9920)

Thanks

I have found it is a mounting issue. I can run a different motor in the truck with same problem with the diff. I have tried a different esc as well with same problem. I put a tranny back in it and tried that. I t worked like a charm. It is really confusing me. I have tried different radios as well. none seem to help. I get it straight one day.

The problem has been eliminated, it was a mounting problem. Even moving it like 1cm away from the tranny/chassis makes a massive difference.
