I just wanted to let everyone know that Aircraft Spruce and Wag-Aero has a new control lock for PiperSport/SportCruisers, all the Vans aircraft and nearly every plane with a stick. It only weighs a few ounces and is only $44.95. If you are tired of using your seat belts, you really need to check this out. It works great on my PiperSport.
