Design and development

The LO-120 was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever high-wing, a two-seats-in-tandem open cockpit with a small windshield, fixed tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft is made from wood, with its flying surfaces covered in doped aircraft fabric. Its 15.5 m (50.9 ft) span soaring wing has an area of 16 m2 (170 sq ft) and can be quickly swapped for an alternate, reduced span microlight touring wing that increases cruising speed. The tail is an inverted V-tail mounted to twin booms. The standard engine is the 40 hp (30 kW) Rotax 447 two-stroke powerplant.[1]

Cockpit access is via a sliding fairing.[1]

gollark: There is a 10000 digits of tau thing up on the tauday page, but they don't list how they get it.
gollark: For Pi, you have magic formula like these for getting digits. I'm annoyed that there are none I can find easily for Tau.
gollark: Also, please, anyone silly enough to be using potatOS and the tau viewer in the first place probably will.
gollark: I couldn't live with myself if I did that...
