mamba max pro and mamba 2650 in 4s?

[magman]

The 2250 on 4s would be better due to the motor being designed more towards the truggy line. Also, if you use the mm pro I would install an external bec to help ease the temps a bit due the the weight of the truggy.

In saying this, your set up will work just pay close attention to temps

I run the mmm w/the 1520 on 5s in my Truggy and it runs cool as can be. My set up is overkill, but it runs great!
