So are you guys saying that the EMF is causing the ESC's to fail prematurely? If so, should I be running mechanical brakes on 5s 6500mah Lipo's? If so, how do you assign reverse on a Spektrum DX2 to actuate the brake servo??? I'm all for it if it will stop the Monster failing again? Or are you recommending not running over 4S?

I wouldn't call what I said "official", it's just my tendency to not run things to the max specs. I routinely run both my MMM systems on 5s with motor brakes and no problems so far.

Thats fine mate, I know it can't be catergorised "official", but I know your a well respected member of the forum with a wealth of practical knowledge and I value your opinion.

I'm somewhat trying to get my head around why after doing all the reading, setting up my car how I considered "best practice", taking temps at multiple stages of the first run, I still blow the ESC in like 20 mins???

Would you consider my setup excessive or borderline or is it just "one of those things"??

If I gear down to 13/48 won't that just give me more torque and make the motor hotter?
