My entry for the light aircraft challenge
I tried making the specs as close as possible to the real think and i'm satisfied with the result. It's very light, so you may need to steer a bit during takeoff

Info

The Diamond DV20/DA20 Katana is an Austrian-designed two-seat general aviation light aircraft. Developed and manufactured by Diamond Aircraft, it was originally produced in Austria as the DV20.

The Diamond DA20 Katana is a low-wing cantilever monoplane, commonly operated as a low-cost two-seat trainer aircraft. According to Flight International, it has been considered to be relatively unorthodox amongst trainers, utilising a design that makes heavy use of the manufacturer's prior glider products. The Katana benefits in the training role from its relative ease of handling and responsive controls. In comparison to traditional trainer aircraft, it has been marketed as substantially reducing the associated fuel and maintenance costs of operation, while providing favourable flight qualities and the necessary range for trainees to gain experience with. For a time, the Katana was the only two-seat composite training aircraft available that offered both low costs and incorporated advanced technologies, giving it an effective niche in the sector.

The Katana has several distinctive features, including its all-composite construction, low-mounted wing, T-tail arrangement, and a castoring nosewheel. All models make use of a composite airframe which is constructed of glass- and carbon-fiber reinforced plastic. The one-piece fuselage has removable wings, which assists with transportation and servicing activities. The wings themselves have transparent plexiglas panels present so that key control elements can be readily inspected without disassembly. The airframe is complete with a sleek finish across the entirety of its exterior, which serves to eliminate corrosion and rivets in order to lower maintenance requirements. The maintenance costs of the Katana have been considered to be relatively low.
