Two unusual modifications produced a biplane glider and a low aspect ratio parasol wing machine.

Generally known as the Sport, Farman's post World War I light biplane tourer carried the maker's designation FF 65.

[1] The Sport was a single bay biplane with staggered wings of equal span and rectangular plan.

An open cockpit began just aft of the first pair of centre section struts, with two low seats in tandem, spaced so closely together that the passenger's feet surrounded the pilot.

This latter carried a tall rudder with a curved top which extended to the bottom of the fuselage, moving in a gap between the elevators; there was no fixed fin.

It had a fixed conventional undercarriage, with its main wheels on a single axle mounted on V struts to the lower longerons.

[2] David was powered by a 60 hp (45 kW) Le Rhône 9Z rotary engine, neatly enclosed within an aluminium cowling and driving a two blade propeller.

[1] Sports fitted with extended upper wings gained first and second prizes at a speed range competition that year.

Modifications had to be made to accommodate the change in centre of gravity once the engine had been removed and the unusual biplane glider had a lengthened nose and wings without stagger, the upper plane moved rearwards.
