Kazurov-Poluchkine-Rusakov Chtyvnoplat (Hybrid)

A single-seat single-engined high-wing monoplane with hybrid control circa 1983. Wing has unswept leading and trailing edges, and constant chord. Yaw control by rudder. Control inputs through weight-shift for pitch/yaw/roll.

The Chtyvnoplat appears from the very sketchy information available to be a Russian equivalent of the Quicksilver E. It differs from the Eipper-formance machine in that the pilot lays prone, but the control system is similar, being primarily weight-shift but assisted by a rud-der. The high rectangular wing has a large dihedral and a single boom supports the tail, the whole structure being supported in flight by a web of cables of considerable density.

The claimed glide ratio is 15-17/1.

Length overall 17.1ft, 5.20m.

Constant chord 4.8 ft, 1.46 m.
Total wing area 151 sq.ft, 14.0 sq.m.
Wing aspect ratio 6.5/1.
