The N-52 Started as a design experiment at Nihon University. Three test airframes were funded by Asahi Press for analysis.

Design

The N-52 is powered by a Continental A-65 engine. The aircraft features a single open cockpit with side-by-side seating and a taildragger landing gear. The aircraft was designed to accommodate up to 100 hp (75 kW) engines. Controllability with a 65 hp (48 kW) engine was considered sluggish.
