i have a HPI rush with 21 turn motor in and a eletrical starter(got too many blisters of the pull starter). the thing is with such a powerful motor in the backend goes right to the ground even with the hardest shocks in when it accelerates. i have had a looked at it and there is room to add another pair of shocks on the back, would it be worth it o am i better off changing the motor to a less powerful motor. any advice would be helpful
