Military Diesel Bike Engine

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

I doubt that a motorcycle engine would have enough power, even for a
single-place helo. Helicopters require 50% or more power than equivalent
fixed-wing aircraft.

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.

Lombardini? They make a small (~25Hp) diesel 3 cylinder. The only
thing keeping me from putting a Briggs + Stratton (Diahatsu) 3 cyl
diesel in my Quickie is cost. The Diahatsu motor is far smoother and
lighter than the Lombardini or the Kubota. They even make a
turbocharged version that puts out around 32 HP - no PSRU needed.

If you're thinking about a half VW, also check out the 1/3 Corvair at
www.ultravair.com. Also, what Wankel have you looked at? I tried to
research rotaries of a small displacement type, but had no luck.
Thanks

Brain fade... see if this helps.

I was involved in a military program that used an engine from this
company. It was nicely done and seemed to perform well. I beleive that
the bird is now in service (UAV).
