The setuup is simple; the main fan gest the Razorback off the ground, the rear fan gets the hovercraft going forward, and the rudder gest it to change direction. The steering is taken care of by the micro servo buried in the foam.
Everything that powers the hovercraft is creatively stuck into or onto the foam chassis. Right smach center of the chassis is the main fan, and
pointing out the back is the go fan, both of which appear to be hot
glued to the foam. The speed controls are servo taped to the foam and the receiver and battery pack have molded recesses to tuck into.
