Dave: I looked at your site on the Unicopter and Sychrolite and saw the
references to the rotor governor, but couldn't tell just how this device was
supposed to work. I cautiously assume that it senses rotor speed and
collectively adjusts pitch to keep the blade speed at some pre-selected rpm?
I also assume that the pilot would have an override for this feature? Do
you know where I can read up on the use of the governor and why that device
hasn't continued to this day? It seems the R-22s might like to have one if
the downside was not too steep.
An aside issue, you state that the need for yaw control of the Unicopter
would be more like a fixed wing. With the exception of hovering, I find the
yaw control on my helicopter to be less than that required by the fixed
wings that I have flown. e.g. no need to lead the turn with pedals to keep
the ball centered. A lot of the multi rotor systems supporters seem to
think that the use of the anti-torque pedals requires a lot of training. I
did not find that to be true at all. Even in the hover. Are you helo
rated?

Stu,

"....has demonstrated flight but is not mechanically capable of
autorotation. Am I missing something?"

Re autorotation;

It might be of interest to know that the first production helicopter, the
Flettner FL-282 had a rotor governor. In addition, Igor Sikorsky's chief
rotor designer, William Hunt, invented a rotor governor for the R-5. The
rotor governor provides automatic entry into autorotation.

Perhaps an article on this subject in your 'Experimental Helo' magazine
would be of interest.

There are several firms offering either plans for, or kits, for
homebuilt
helicopters that have little if any supporting actual flite test data.
Yet
apparently there are willing buyers out there willing to part with their
money for these subjects of marketing rhetoric. Even EAA gave some
notice
of one of the offerings which adds or implies some credibility to the
offering. In this case, the aircraft has demonstrated flight but is
not
mechanically capable of autorotation. Am I missing something? Are
there
that many people out there that just believe the marketing rhetoric
without
having seen a demonstration or having access to an independent test
report?
I know that I don't part with tens of thousands of dollars just based on
the
advertising.
