Yup, about 1 millisecond after I hit send my brain got an extra
molecule of oxygen and I remembered the difference in blade pitch... I
cringed because I expected to get blasted by the group, but so far
everyone has been kind...
I still expect this machine to fail in the marketplace...

I can confidently predict that like Moeller's Skycar they will still be

The gyrocopter is always in a state of autorotation, that is the flow goes thru
the rotor from the bottom to the top.A helicopter goes from the top thru the
bottom .So in order to change flow direction and autorotate the pitch must be
changed . In a fix pitch design this cant be done .So in the event of an engine
failure the royor(s) will slow down and lose lift.

I'm sure if they advertize on ANN zoom would give it rave reviews and a puff
piece on how well it flys. That's what he has done before.

See ya

Waiting on pins and needles for his flight test report. Exhilerating

When Fetters was advertising in zooms US Aviator zoom was giving Dennis rave
reviews.When Dennis quit advertising zoom quit the rave reviews. When I first
zooms "pilot report" on the mini 500 I read something in the article that had me
fall on the floor laughing. When I worked for Scheutzow Helicopter we often took
potential customers for a demo flight .If our pilot felt that the potential
customer was a good enough pilot to solo he would let the guy take the
helicopter up.

If he wasn't good enough the pilot would land and tell me "we're gonna do a
little post flight debriefing before we go again, how about giving it a quick
once over". That was my signal to pull the magnetic plug on the tail rotor gear
box get some oil on my finger and go to the drill press for a little bit of
shiny metal debris to mix with the oil. Then I would solemnly walk into the
office and tell Tim .Gee I just found some metal on the plug and I really should
tear down the gear box and check it while showing the oily finger with tiny bits
of metal to both him and the customer.

Naturally we all agreed that it was better not to fly then take a chance on a
tail rotor failure. Thereby letting the customer down without having to damage
his pride by saying "your a crummy pilot and we don't trust you with our
machine".Webb who was the owner of the company said that was a move they did
when he worked for Hiller Helicopter.

So when I read zooms account of his test flight of the Mini 500 he wrote ,and
I'm paraphrasing, "I landed and we took a lunch break but my afternoon flying
session was cut short when some debris was found on the magnetic oil plug."

I often wondered if Dennis knew the old trick or if there really was some debris
on the plug and that was his way of keeping zoom out of the machine:-)
