PIK-16C Vasama
 
The PIK-16C Vasama (or Arrow) single-seat Standard Class sailplane was designed by Tuomo Tervo, Jorma Jalkanen and Kurt Hedstrom. The prototype first flew on 1 June 1961 and had a 'butterfly' V-tail; the PIK-16A and PIK-16B were followed by the major production version the PIK-16C, which has a conventional tail unit instead of the earlier V-tail, and several other improvements, such as a sandwich-type construction for the wing leading edge. In 1963 the PIK-16C was awarded the OSTIV prize for the best Standard Class sailplane, and at that year's World Gliding Championships held at Junin, Argentina, a PIK-16C was flown into third place in the Standard Class by Juhani Horma of Finland; the type also set up several Finnish records.

PIK-16C Vasama

 

The PIK-16C was put into production by K. K.Lehtovaara O/Y of Hameenlinna and a total of 56 of all variants were built. The Vasama is of all-wood construction, the cantilever shoulder wings being built of pine and birch wood and having an exceptionally low (for a sailplane) thickness/chord ratio of 14% at the root to give a good optimum glide angle. The shaped box spar of birch plywood forms 40% of the chord and takes the bending and torsion loads. Aft of the spar the top surfaces are plywood-covered and the under surfaces fabric-covered, and there are spoilers in the top and bottom wing surfaces. The plain ailerons are of ply-covered wooden construction, and all the Vasama's surface areas are highly polished to help give it a higher performance. The monocoque fuselage is of plywood construction with a glassfibre nose-cap, and the pilot sits in a semi-reclining seat under a removable blown Perspex canopy that extends some way back past the wing leading edge. Landing gear consists of a non-retractable monowheel with a brake, and a skid under the nose section. The tail unit is also of wood, with a trim tab in the port elevator.
