FeaturesThe E-flite UMX ASK-21 is a scale RC sailplane of the renowned two-seater designed by Rudolf Kaiser and built by the famous Alexander Schleicher GmbH & Co. A first of its kind, the UMX ASK-21 is an elegant fully functional 4-channel aircraft that, at altitude, is capable of loops and rolls, as well as thermal or slope soaring that's popular around the world. Lightweight and sleek, its onboard AS3Xª System is custom tuned to offer the silky-smooth experience of flying a giant-scale sailplane, even in breezy conditions. Like a giant-scale sailplane, the UMX ASK-21 is equipped with remote tow hook release control making it aerotow capable when paired with a powerful RC airplane like the E-flite UMX Carbon Cub SS (EFLU1180). YouÕll find that its onboard AS3X System is excellent at stabilizing the various flight conditions an unpowered model can encounter, especially at high speeds during launch on the Hi-start or tow line. The UMX ASK-21 can be ready for its first flight in just a few minutes. Just charge the included Li-Po battery and bind to your own full range DSM2ª or DSMX¨ 4-channel transmitter, such as the Spektrum DX4e.
