Development

Toyo Aircraft was established in June 1952 and their first aircraft, the T-T.10, was completed by the end of the year. It is of mixed construction; the wing is built entirely from wood and fabric around two spars, with a plywood skin enclosed within fabric. The flaps and ailerons are wood framed and fabric covered. In planform the wings are straight tapered with rounded tips; most of the taper is on the trailing edge. There is 6° of dihedral. The T-T.10's tail surfaces are also straight tapered with rounded tips, generally wood framed with fabric covering. Its horizontal tail is mounted at the top of the fuselage. The elevators have a cut-out to allow rudder movement, as the latter extends down to the keel. There is a trim tab on the port elevator.

The fuselage of the T-T.10 is fabric covered over a welded chrome-molybdenum steel frame. The engine is a 140 hp (104 kW) Lycoming O-290-D2 flat four, driving a two bladed propeller. Student and instructor sit in tandem with dual controls under a multi-framed, continuous, two part sliding canopy. The rear fuselage line is raised compared with the forward section, but not to the full canopy height. The T-T.10 has conventional landing gear, with narrowly faired cantilever, coil spring damped mainlegs and a tailwheel.

The first T-T.10, registration JA3026, flew for the first time on 30 December 1952; the first production model (JA3049) followed soon after, on 11 February 1953. Production numbers are not known exactly; one report speaks of a "small batch" but only the first two T-T.10s appear in the single engine serial range JA3001 - JA3100, which covers the period August 1952 to September 1955, so they may constitute the whole batch.
