Assembled, we've done the soldering for you! Manual Control: The servomotors are controlled using the two joysticks on the controller. X and Y direction of each joystick each controls a servomotor. This totals four servomotors. To control servomotors numbered 5 and 6, one presses and holds the left shoulder button, while using the right joystick. Includes instruction manual. For more information, please see the February 2011 edition of SERVO Magazine.
