But Kasprzyk did not design the BKB Bekas glider that started all of the so called Kasper Wing designs.

He was was a very good and safe pilot and did an excellent job promoting the design and demonstrating its performance potential.

Well the BKB and Bekas are two different machines. He participated in the design and construction of the BKB but the Bekas was all his although all he did was stretch the spar, substitute a Wartmann airfoil, and change the pod shape. When they tried to fly it in the 60s it fluttered and crashed so he apparently screwed up the spar.

Kasper has an interesting history. I believe almost everything he designed had a problem and some of design claims were suspect. When Henryk posted the pictures of the Kasperwing copy getting ready for flight I was hoping it would give some answers but unfortunately it crashed too.

=some time ago we have got a drawings (9 x 1) m ! of BKB1 AR=10 glider

which was modyfied by Witold Kasper into BEKAS-N ("narrow") with AR=15 .

=BKB1-A =modyfied and explored by W.Kasper (triangle wingtip extention+stabilizers
+greater rudders =full AEROBATIC wit NO altitude restrictiones )

=BEKAS1-A =1.2 m chord ,restored in Poland,

after exellent car towings ( from 3 m high was flown circa 300 m !)

was destroyed in first, 22 sec.aerotowing (WILGA !)





this thri tailles glider have NACA8-H-12 airfoil.
