[1] In 1936 students at the Tokyo Imperial began a similar, two-year project, though for a small two seat powered aircraft.
The LB-2 was powered by a 60 hp (45 kW) air-cooled, inverted, six cylinder Train 6C, a French engine which proved unreliable.
The tail was conventional with its tailplane on top of the fuselage and a triangular fin mounting a rounded rudder.
[2] After the students' design work was finished most of the LB-2's construction was undertaken by Nihon Koku Kogyo KK, a Yokohama-based company.
The project was judged a success, though the LB-2's flying time was severely limited by the wayward Train engine.
