Stampede brushless help.

Yep, the Mamba Max is the way to go. I think you will be happy with the 4600 or 5700. The 4600 may be a little slow for you, but the run times will be insane, so you may want to go for the 5700 which wil be a mix of both.

As for gearing this is what someone else wrote, would work great on a pede:

the sweet spot in a flm pede is 83/15 on 6 and 8 cells

Although yours isn't all aluminum, you can still start here and then change the gearing accordingly.
