Design and development

The Sbach 300 is an all-composite design, predominately constructed of carbon fibre. It features a cantilever low-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear and a single engine in tractor configuration. The aircraft's 7.50 m (24.6 ft) span wing has an area of 11.25 m2 (121.1 sq ft) and mounts full-span ailerons with spades to lighten control forces, which give a roll rate of 450° per second. The standard engine employed is the 315 hp (235 kW) Lycoming IO-580 four-stroke powerplant. The aircraft has an empty weight of 570 kg (1,260 lb) and a gross weight of 850 kg (1,870 lb) for aerobatics and a gross weight of 999 kg (2,202 lb) for non-aerobatic flight.[1][2]

The 300 was later developed into a two-seat version, the XtremeAir Sbach 342, which was introduced in 2007.[1]

Operational history

The Sbach 300 was flown to a German national aerobatic championship in the unlimited class.[1]

gollark: It's apparently not very effective for kidnapping (takes ages to work) but *can* give you horrible cancer and whatever.
gollark: Opposing it got considered "green" somehow by the magic of political dimensionality reduction and if that hadn't happened it might be more popular.
gollark: Quite possibly.
gollark: I guess evacuation kind of counts as that?
gollark: Solar panels, though, aren't great for anything but small off grid systems: they take up tons of space, require large amounts of energy to produce in the first place, stop working after a few decades, and don't produce power all the time.
