Could this work for a small helicopter, like the kind BJ Schramm was marketing?
Comments?


TheRoyal Enfield diesel bike (made in India) used an Italian diesel
engine - and is SLOW, HEAVY, and rough riding.
From someone who has ridden one, he says they can hardly get out of
their own way with one rider. (something like 15-20HP on the big one)

Pretty sad for an 850 CC engine.
The Enfield Robin may be better - I think it was a Fuji Robin engine..
Still heavy and gutless.

On a Helicopter, I think it would be safe to say it would never "get
off the ground"


Years ago I sold my Quickie ( single place ) to a guy who was a diesel
"nut." He put a diesel engine in it that he said put out about 20
h.p. Don't know the name of the engine, but I do remember him saying
that it came from Italy. I did the test flying for him since he
wasn't familiar with the plane. My "test flying" consisted of low
altitude hops down a 7000 foot runway. He later reported to have put
over 100 hrs. on the plane before he sold it. The engine (
installation ) seemed very simple and it burned ( according to him )
about half a gallon/hr. With an 8 gallon tank...that's 16 hrs flight
time. The only way you could stop the engine was to cut the fuel
supply. The only problem was it vibrated like hell.
