My overview of the Mamba Max 5700

I believe you Crazyjr. I dont think the 5400 would actually make a good performance in Sower's lightning stadium truck, though.
He either should go to the 4600 or simply pick up himself a good segmented motor and couple it with the Mamba Max controller. It would ease the controller a bit.
There's quite a difference between your T4 and his truck, if you can see what I mean.:)
