Wilksch Aero is a 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 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 are competitive across this power range and offer the advantages of direct drive and air cooling.
