For anyone who is in the market, there will be a good opportunity to compare the ASK-21, PW-6, Blanik L-23, and SGS 2-33 side by side at the same airfield at Sugarbush Soaring in Vermont this summer. www.sugarbush.org The PW-6 will be new. The other gliders are in good condition.

The conversation comparing the relative merits of the various designs will be continuous throughout the summer. Lots of pilots. Lots of CFI-Gs. Pleasant weather. Bring your glider. Open 7 days a week.
