Arado Ar 77

The Arado Ar 77, a German twin-engine monoplane, was developed as an advanced training aircraft starting in 1934.
Featuring a thick cantilevered wooden wing, the Ar 77 had plywood skin on the under surfaces and fabric covering on the upper surfaces.
The fuselage was constructed from welded steel tubing covered with fabric, while the tail surfaces were made from steel tubing and fabric covering.
Unlike Arado’s typical design, the tailplane was high-mounted on the fin and supported by steel tube ‘N’ struts.
The elevators and rudder were fabric-covered, aerodynamically balanced in the Ar 77A and lacking aerodynamic balance horns in the Ar 77B.
Equipped with a fixed tailwheel undercarriage, the Ar 77 had cantilevered oleo pneumatic main leg struts with brakes and a tail wheel under the rear fuselage.
