I'd almost go buy one for you just so you could test. I wouldn't rule it out at this point. It shouldn't be that, but far stranger things have happened. My new motor/esc should be here tomorrow. Which means I'll have it going by this weekend. If I still have issues after a few days, I'll throw an rx pack on and let you know.

I don't think that would have anything at all to due with my heat issues, but who knows, I could have more than 1 problem.

Either way, I wish I could talk you into running to the store and busting out a few bucks for an rx pack to test with, they're really cheap...
