motor with speed and torque trade off

Electric motor with speed and torque tradeoff. This setup works well for vehicles built for climbing or speed. If your vehicle does a wheelie than pull the slider to the left (more speed slower takeoff speed). If the vehicle won't climb a hill than pull the slider to the right (more torque but slower speed). Feel free to edit and build a vehicle around it. Also works well with mini transmitters and receivers instead of wires
