From GWS the first-ever park flyer retractable gear system. This easy-to-install system is perfect for semi-scale park flyers like the GWS Zero, and weighs little more than a tenth of an ounce. Comes with landing gear and a servo-actuated retract mechanism. All that's left to buy is a sub-micro servo and your choice of ultralight wheels.  This is one of the least expensive, most exciting upgrades any park flyer pilot can add to their plane.
