The 'Ghost Squadron' give a superb demonstration of both unpowered and powered gliders at the BMFA Power Nationals 2017. The Minimoa is a classic design with its gull wings. It gets pulled up by a tug fitted with a 100cc engine. The racing glider is powered by an electric motor with a single blade propellor that is automatically deployed from within the fuselage into a vertical position before it starts up.
