The 17 meter ASK-21 is a two-seater performance glider still in production. It was designed for instruction, training, aerobatics and cloud flying and has a glide ratio of 34:1. It's gentle flying is as well loved by the students as the instructors.

All parts of the model are model in the traditional aircraft technology. Two component paint is used to color the parts, so they will keep their white aspects for years. Wing joiner and locating pins a factory installed during the moulding process. Servo wells for the aileron and airbrakes are ready receive their servos. A substantial square aluminum wing joiner is used. A fibreglass canopy frame and removable wheel covers (as full size) are competing the kit.

The flight characteristics are just a pleasure, smooth and docile handling. With a such a low wing loading for this size aircraft it will just float. Its very large stab (for its size again makes it an incredible stable airframe. Thus it has great thermalling capability, low speed turns are forgiving. Even at high altitude, the plane is easily recognisable because of it huge wing chord.

Since its construction is very sturdy, any aerobatics is possible, while it doe3s not have the roll rate of a Swift or Fox, it will do it as a king. Even snapping and hammer heads are not a problem.

this ASJK-21 is also well suited for the installation of an sls, its large fuselage provides many installation possibilities. And the weight penalty will not affect its flight characteristics. Current offering will fit in this plane, like the AFT 25 or SLS belt driven 22". And with the long nose the battery can be used top balance the plane without any problem
