Single seat single engined flex wing aircraft with hybrid control. Rogallo wing; tail carries rudder and horizontal stabiliser. Pilot suspended below wing in trike unit, using bar to control pitch and roll by altering relative positions of trike unit and wing. Control input through pedals for yaw. Wing braced from above by kingpost and cables, from below by cables. Undercarriage has three wheels in tricycle formation. Engine mounted below wing driving pusher propeller.
Two Rogallo winged microlights are known to have been produced under the umbrella of this organisation, both of them attributed to Yevgueni Chevcheriko. As such they are hybrid control aircraft and are best described as ‘trike plus rudder on trike unit’. The trike unit is hung from the Rogallo in the normal way and the relative positions of the two can be altered to give pitch and roll control, just as in any other trike, but instead of relying on roll to initiate yaw, a separate rudder is attached to the rear of the trike unit, controlled by rudder pedals.
The Russian aircraft have a horizontal stabiliser behind the pilot. The Ptica 2, the earlier of the two Russian designs, has a large windscreen. The Ptica 2 has a 42 hp engine, 4 hp less than the SPM.
The initials SPM stand for Siniaya Ptica Modernisovanna, and it is basically an updated version of the Ptica 2.
