What the heck, I guess I'll throw my $.02 in the barrell too. I'm stoked about this. I'm pretty confident the MMM won't have issues out of the box if used within it's specs up to 6s. I'm also stoked on it over the MGM because it will have reliable reverse, brakes, programming flexibility, and it has a better built in BEC. The MGM only went up to 5v and I wasn't happy with that. A steering servo on 6v is a beautiful thing.
Oh, and I won't be able to race anything until March here in Idaho anyway. Too wet or cold.
