Just some quick information on the MM esc

Have any of you guys tried a 5S pack with a MM? That would bump me just a little to keep me in the same speed range I am now with the IBs and the 18/38 gearing I'm presently at. I guess I could use a 4S if it's safer for the system and go to my 20/36 gearing and maintain the same approx. top end. I have no shortage of torq right now.

I'm thinking it's about time to start making the lipo switch.
