The E-flite® UMX™ ASK-21 model 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 plane 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 AS3X® 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 plane 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). You’ll 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 plane 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 DSM2® or DSMX® 4-channel transmitter, such as the Spektrum™ DX4e transmitter.

In this case, do not hesitate to ask me to add it : You're not bothering me. Please be patient, depending on my workload, I may take a few days to work on your model and gather information.
I'm sometime asked to add a non flying model to this library but unfortunately, it's not the focus of this website
