LETS START WITH A LITTLE HISTORY: 

The Orion G-801 was designed by a man of genius, Jean GRINVALDS, to whom we will be endebted forever. His goal of experimentation was to conceive a new configuration for an aircraft of general aviation allowing better performances and, if possible, better confort. This aircraft has the advantages of several modern technologies such as aft engine/propeller and composites construction.
