Current MM still ok on 4s?

[mxracer]

price is 310 ausd.. our dollar is a bit weaker than the USD

ps MM on 4s is sweet . i dont understand how castle can make a esc thats rated at 2-3s lipo 100 amp and is very quite realiable even when over driven into 4s. yet the failure rate on MMM looks to be huge . im going to stick with mgm and MM until MMM problems have been fixed.

PS why doesnt the kontronik jazz 63V have brakes look at the specs of that esc . its the ultimate !!!!!!!!!!!!!!
