Design and development
The R-3 was a small biplane trainer of mixed construction. The wings had wooden structures and were ply-covered around the leading edges and on the undersides. Their covering was completed with fabric over all surfaces. Interplane struts were metal and the fabric-covered ailerons, fitted on both upper and lower wings, had metal structures.The fuselage was a fabric-covered steel tube structure. The engine mountings accepted several versions of the ADC Cirrus engine, the Cirrus II, Cirrus III or Cirrus Hermes. Instructor and pupil had separate open cockpits in tandem, equipped with dual controls. Its conventional landing gear was also steel, with oleo-rubber landing legs.
