I have a question for the guys who know.

I can't say for your exact case, but I have 2 very close in speed setups that I use in my Rustler. The first one is the MM and the 7700 Kv motor geared 13.95:1 running 3S2P A123 it's geared for about 58 mph.

The other setup is using 4S4P A123 and a 3300Kv motor geared 8:1 which is about 57 mph.

The 3300 Kv motor is harder to keep the front end down when you first start taking off, but the 7700 seems to really come alive at about 3/4 throttle. If I had the chassis sorted a little better I think the 7700 would be a little easier to control. Its a bit of an extreme spread between the 3300 and the 7700 but both setups run the same speed and it gets real hard for me to control anyway.

Hope this helps.
