The Arado Ar 77 was a German twin engine monoplane, designed as an advanced training aircraft from 1934.
The Ar 77 had a thick cantilevered wooden wing, which was skinned with plywood on the under surfaces and covered with fabric on the upper surfaces.
The fuselage was built up from welded steel tubing covered with fabric.
The tail surfaces were built up from steel tubing and were also fabric covered, not following Arado’s trademark layout of a fin and rudder forward of the tail plane.
Instead the tailplane was high-mounted on the fin and supported by steel tube ‘N’ struts.
Elevators and rudder were covered with fabric, aerodynamically balanced in the Ar 77A and without aerodynamic balance horns in the Ar 77B.
The fixed tailwheel undercarriage consisted of cantilevered oleo pneumatic main leg struts fitted with brakes and a tail wheel under the rear fuselage.
