Our new sailplane launching platform allows you to reach optimal thermal hunting altitudes without the expense of a winch or the hassle of a high-start. Great for clubs that do not have the space for traditional sailplane launch systems. The platform is made from a 6mm carbon/lite-ply sandwich and mounts to your favorite, 70″ (1780mm) or larger, high-wing model.
