I will test the stock 3PK module and receiver with the system, I forgot about that. I put it away because I hate the HRS receiver it came with. I don't know if that would give me any more insight into the problem with the Spektrum system, though. The system all worked in the car it was just pulled out of, on lesser power/milder motor.

I don't have a receiver pack handy (or open outlets in the Rx), as I never ran them in my stock or 19T 12th scales. I might have to jimmy rig something to test that with though. Should a receiver pack work properly in the car, I don't plan to run one full time, what would the solution be for a voltage spike to the radio from the ESC?

Oh, yes, something else, too... this exact same motor and battery combo, with the same Tx module and a different Spektrum Rx performed flawlessly in the 2wd car only days ago. I'm wondering if the amp draw and load in the 4wd car is exceeding some power capacity somehwere?
