Fokker DVII was the best fighter plane of WW2. It had a welded steel tube fuselage with wooden wings. It was known to be strong, fast, agile. It had a BMW 220 horsepower engine with 6 inline cylinders. I once owned an old BMW 735i – it had a six cylinder inline 6 BMW 3 litre engine. I often wondered if it wasnt the same engine just a bit higher tech and probably shrunken.
