On April 22, John Romain made the first flight of Bf 109G-10 registered N90602 in Madras, Oregon. It is a Hispano Buchón, re-engined with an Allison engine.
The engine cowlings are identical to those of wartime Bf 109G, giving the aircraft an identical appearance. The only visible difference is that the propeller is a shortened DC-3 propeller. This choice of engine offers several advantages. The Allison engine is far more available and cheap than the original DB 605 engine, with more readily available spare parts as well as cheaper operating costs and easier maintenance.
