Hello; I personally don't think anyone would be interested in flying a plane with engine that has to be hand spin to start but would make a Good leaf blower to mount on to my John Deere lawn mower. Bristol Hercules (type 759, 2068hp take of power) was built up to 1964 under licence in France by SNECMA for the military transport aircraft Noratlas! The guy in front of the Harley rental store running the 1,000+HP engine isn't a terribly bright individual. How is it that the engines mounted on stands or trailers don't pull away? It seems like a few trailer stabilizer feet would not be enough to anchor the rig down. Awesome compilation!
