 It had outboard ailerons but neither flaps nor airbrakes.The fuselage was an open frame structure with two horizontal, parallel booms that ran rearwards from the wing spars to the tail, where two cross braces carried the tailplane.A pair of N-form struts converged below the wing onto a third boom, horizontal below the wing then angled upwards to the tail, joining the rear cross brace via a short vertical member and two angled ones.
