The prototype is fitted with a 1600 cc Subaru EA 71 engine, propeller directly fitted to the crankshaft. The engine is lightened, all redundant aluminum is milled from the housing and the steel oilpan is replaced by an aluminum one.
The cooler is placed in the starboard wing.
Other engines that will do the job are the 1800 cc VW and the 80 HP Jabiru although this one would not fit in as nicely as the other ones.
You can also install a 2 stroke like the Rotax 582 but the fuel consumption will be more.
