SO! Now I am getting into RUNNING This Venom Bike.. and its NOT SIMPLE to keep upright, with my limited experience.. BUT! It has HUGE potential with some practice ahead. I did Roll the bike from side to side.. I flipped it and beat on it.. and it STILL was RUNNING at the end! My 5450mah 2S lipo ran for about 20 minutes give or take a few.. and was totally FUN! I know with some more time behind the stick.. I will be able to master this amazing rig made by VENOM! Their products are really coming a long way!
