The company is using Honda L15-series and Mitsubishi car engines for their conversion to an aircraft application. You may buy them new from Honda but most customers opt for used engines that have been used in cars for less than six months or 5000 miles. After they leave the Viking factory assembly line they can be considered as a rebuilt/new aircraft engine.
The result of this hard work is an engine with the latest technology for the lowest price available. The fuel economy is world class; the power to weight ratio is superb. The quality of the engines is as good as Honda gets it and to ensure reliability, Viking performs dynometer testing combined with thousands of hours of in flight testing.
Honda / Mitsubishi builds these engines in thousands per year (unlike other aircraft engine manufacturers) with enough parts readily available and, more importantly: for a reasonable price. This guarantees the customer benefits from the absolute latest in engine technology for the best price.
To get an idea of how the Viking engine is constructed on the inside you will find below an image gallery of the internals of the Honda/ Viking engines. Although not complete, it gives a good impression:
As can be seen in the above images, Viking Aircraft Engines is using the absolute latest available engine technology for their aircraft engine conversion from either Honda or Mitsubishi, you will not find these innovations in other engines. The Viking can be bought either new or lightly used with full documentation where the engine came from and mileage upon request.
