You can fire without any grip strength or finger movement. You can fire with either hand. You have loads of fun for hours. Most joysticks require people to grip them. The QuadCommander is designed so that you can use it without gripping.
Quads then control the joystick by moving the arm.
Since quads can not do that, the QuadCommander is designed so that you can operate the buttons by pressing with the hand or wrist, even while maneuvering the joystick. Further more the QuadCommander comes with two sets of fire buttons. One set is on the joystick and rest on, and are are actuated, by the wrist. The other set of firing buttons is on a separate console called the Quad Command Module. You can fire the buttons on this console with the palm of the hand not using the joystick.
