About Us

Wilksch Aero is a VAT registered consulting and technology business run by Mark Wilksch.

Mark Wilksch founded Wilksch Airmotive Ltd in the UK in 1994 and assembled a small team who brought the "WAM-120" to the non-certificated aircraft market.  The engine suffers no weight penalty by comparison with the established air-cooled Avgas fuelled engines.

In 2005 Mark reduced his equity stake in Wilksch Airmotive and handed control to an investor group consisting of lead by Mike Newton.  The Company continued development of the "WAM" engine while Mark Wilksch separately concentrated on Direct Injection (DI) aircraft engine concepts.  Mike Newton subsequently announced a restructuring of the assets into a new corporate entity with revised ownership as part of Apple Tree Innovation Ltd.

In 2007/2008 Mark worked for Teledyne Continental Motors in the USA, delivering remarkable weight savings and other improvements to the venerable O-200 engine, an update that allowed it to meet Cessna's requirements for the new 162 "Skycatcher" Light Sport aircraft.

Wilksch Aero concepts now being developed range from 150 to 300hp.   Two stroke solutions can be cost competitive across this power range and while four strokes can typically compete above about 300hp.   All of the solutions are aimed at certification for manned aviation.
