I have just bought the 7700 mamba max and I would like to put it into the xx4. a few questions.
Will it be too much for the belts?
what spur would you use?
would it be better for me to find the 5700 motor and use it?
any other suggestions?
we're running on a track that is super hard, and the straight is about 110'. videos are at

thanks for your advice in advance
