The RANGER Turbine is the source of air that keeps the RANGERS air cushion inflated and a layer of air moving between the Cushion and the surface of travel.
To Remove the Turbine Lift Fan, first remove the three screws that secure the ESC/Receiver Housing to the RANGERS Deck. Lift out and turn over.
Now you can remove the the single screw from the turbines motor shaft, then place a small flat screw driver between the motor housing and the bottom of the Turbine, and carefully lever upward a little bit until it comes free. Then pull off the rest of the way.
