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.
The 2 meter model is a stand-off scale
reproduction. The difference is in the wing area, which was slightly increased to keep
performance above average. This ASK-21 kit was designed as an economic way to get
into scale sailplane building. It is offered highly prefabricated to put you in the air as
soon as possible. The model was also designed having in mind the newcomer to scale flying,
so this sailplane offers maximum versatility, forgiving flying characteristics, and
excellent performance. It features the E374 airfoil, an easy all-round airfoil to fly. Due
to its low wing loading, it has acceptable performance for thermal flat land flying, yet
will be in his element on the slope to perform nice aerobatic maneuvers.
Two micro servos will have to be fitted in
the wings and two standard sized servos will be used for the elevator and rudder which are
actuated via a cable pushrod and a wood pushrod respectively. You may want to fit a tow
release in the nose for aero towing.
The kit comes with a high quality white
epoxy Fiberglas fuselage. The obechi sheeted foam wings are ready to cover (ARC: almost
ready to cover), and no additional work is required on the wings, except the wing servo
installation. The tail surface is made from 3/16" balsa and the rudder is built-up. A
smoked plastic canopy and all wood and hardware are included to complete the model. Fully
detailed instructions and building drawings are included in the kit.
