Mamba Max motor possible mis-labeled?

I suppose it is possible, but unlikely. You could contact Castle and see what they say.

Even if it was mislabeled, you should still get some very good speed with the 4600 or the 5700. I'm getting a little over 45mph with the 4600 on 2s with wheel-spinning torque in my Jato. I even have the start power turned down and timing as low as possible. I can't imagine running it on 3s!

The 7700 is a very hot motor. That would probably be a 3 or 4 turn motor using the kv ratings of similarly sized S motors. Therefore, your batteries are probably unable to provide the current needed to get that moving under load. Sometimes it's bette to use a lower kv motor for extra torque and simply use higher voltage to get the speed you want. Plus, the added torque from the higher turn motors tend to be a little more forgiving with misgearing.
