We are developing two layout 'Bike' aircraft. The first involves the installation of the engine above the fuselage, and the use of lightweight, glider chassis, similar to that used on aircraft Ki.115 'Tsuryugi'. The second arrangement is provided for the location of the motor under the fuselage. The chassis is not provided, and the launch was carried out with a special catapult. This catapult was developed in the company for aircraft Kugisho 'Oka' Model 43 Father, so starting the truck for the projectile 'Bike' decided to use without modification, as well as an accelerator to be used is solid engine thrust of 7.8 kN (800 kg) and an operating time of 9 seconds.
