A report in of a Helicycle climbing at 600fpm at a density altitude of
8,000. Of course the passenger capacity is limited to only 6 politicians
with the lies removed.



Stu,

I take it from your comment that you don't entirely believe this? ;-)

I have "no" idea what kind of performance the Helicycle has one way or the
other. I have heard that turbines in general do better at altitude, at
least on fixed wing aircraft. Would that apply to rotorcraft too? Do you
think the 2-stroke engines that Mr. Schramm originally tried to put in the
Helicycle would be flying at all at that kind of density altitude?

Just wondering! :-)

Steve: I believe the report. The birds have an abundance of power. People
flying in the low lands of Illinois, Louisiana etc. have modified their
engines, in effect halving the power to get better fuel consumption and
still don't seem to have much trouble flying. There have been other reports
of flying the Helicycle above 11,000. My comment about the passengers was
just a slam at politicians.
I don't know what the performance of the 2 stroke would be. If I had to
guess, I would expect the 2 stroke to be encapable at that high of a density
altitude. Some form of Mixture control would be necessary. I think that
there is one Helicycle flying with the 2 stroke, but I've never heard any
performance reporting.
