Design and development
The Sbach 300 is an all-composite design, predominantly 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][3]
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] Seven XA41s were completed by XtremeAir by 2020, with an additional example completed from a kit. Another XA41, powered by a 360 hp (270 kW) Vedeneyev M14P was completed with the name Angry Fish.[2]
