Hyper 8 Buggy on 6s

OK James, because i'am not sure if i'll keep the mugen MBX5T in brushless mode or if i'll convert the Hyper 7 pro instead and put the new O.S. .28XZ in the mugen.
I would like to have the lighter truck in brushless mode, but i would like to gice a try to the mugen truggy on the track.

Because the mugen with my 1515, 5000mAh, 4s flightpower and mgm 16018, with badland tire weight more than 10lbs.........
