Alexander Schleicher K-21: VH-WKI

Two seat training and fun glider
The AS K21 is a pleasant glider to fly. It is good for training and cross country flight, and is fully aerobatic. While not an all-out performance glider, it is one that people enjoy flying.

The glider’s systems are relatively simple: fixed undercarriage, no water ballast. A spin kit is available for spin training and check flights.

This sailplane was purchased from another club in 2008. In 2012 it received a major re-finish and re-furbishment, and it’s in excellent condition.
