Heres a G/E-maxx MT on only 6s doing a 75mph wheely (too much power).I broke the current 2009 ISC official record and world record with a 81.7 mph pass. Probably would of went faster with less power because I had traction, torque steer and drifting issues when rolling into the throttle the track at high speed.
