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.

Got another report of HOGE in excess of 8500' These things are sounding
better and better.

Cool, Thanks!
