ok I contaced him and he said If I pick up the speed controller from GWS made for the lipoly the 3cell will be fine, he said it has a down converter so that the motors don't fry.

I think I'm going to go ahead and pick it because GWS gives 1 year warranty, so if it frys I'll get a replacement...

I'll let you guys know how it goes.

I'm getting the 370 size motors and using 3x 11.1 volt gws lipoly pack
