Most of the other esc's are tested different from castle, some are even theoretical. But i'm pretty sure castle tortures theirs. I was running two MM's, one 7XL on 5s and the other 9xl on 5s, while the esc's got hot, they never flinched or thermalled. Hats off to castle for making two of the absolute best esc's made. Now that most of the problems are sorted out, It may be time for me to get one (at least) of the MMM's. I plan one for my 1515/2.5d and the other for a 2250 lehner, Possibly in a Summit
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
