You see, we actually USE these engines, not just sell them. At the moment Dr. Vogelsang uses the 60 in his Klemm L25d, the 120 boxer in his 40% Fokker Eindecker, the 170 in his half scale Fly Baby and the 210 boxer in his Wedell Williams Racer. He sold his 50% Jungmeister which had the 420 radial.
All motors are in stock unless noted
Fiala propellers are a necessity for the Valach engines
