boxer style, 4 cylinder, 2600 CC, 95 HP, light weight, air cooled, 3300
RPM aircraft engine, that features a fully electronic ignition and
multipoint fuel injection (FADEC) system as standard equipment.
This computer controlled electronic engine management system has been
used in the automotive rally industry for over 15 years. The system

has an oil thermostat in the system located directly behind the oil
filter, which will bring the engine temperature up to operating
temperature in about 5 minutes.

first engine production and delivery of engines to customers in 2006.
Currently 35 engines have been delivered to customers, flying on nearly
30 different types of aircraft. For ease of mounting the engine is
supplied with 4 mounting positions that are identical to that use on the
