The XtremeAir Sbach 300 is a German aerobatic aircraft, designed by Philippe Steinbach and produced by XtremeAir, of Cochstedt. The aircraft is supplied as a complete ready-to-fly-aircraft.
The aircraft bears the company designation XA41, but is marketed under the name Sbach 300, although use of this name was later abandoned.




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




Operational history


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