MM is fine in a revo - 4s is the best compromise - 5s is good but some controllers won't take it without draining the battery a little.

You do need an UBEC, fan and I would suggest a High Volatage, High temp, low ESR capacitor in the order of 2700f. The novak one at HV one at $10 works or there is someone doing them individually for a few $'s on ebay.

I toasted 3 MM before adding the capacitor and havn't had any issues since - It works (ps even mike uses an extra cap)
