The single-axis electronic throttle control joystick selects motor direction – forward or reverse – and motor speed. The center throttle position has a detent, referred to as Neutral. In neutral no drive signal is sent to the motor. When the stick is pushed in one direction, the motor spins forward. When it's pushed in the other direction, the motor spins in reverse. The farther the stick is pushed in either direction, the faster the motor turns.
