XtremeAir XA41 / Sbach 300


Sbach-300

 

The XtremeAir Sbach 300 is a German aerobatic aircraft, designed by Philippe Steinbach and produced by XtremeAir, of Cochstedt. The aircraft was supplied in 2012 as a complete ready-to-fly-aircraft. The aircraft bears the company designation XA41, but is marketed under the name Sbach 300.

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 wing 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 324 hp (242 kW) Lycoming IO-580 four-stroke powerplant.

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

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