Yes Bernie it does. With centerline thrust, there is no force above
the vertical center of gravity to push it over. You need thrust above
the vertical center of gravity in order to experience
(once-in-a-lifetime only) a buntover. Once you do it, at least you
don't ever have to worry about doing it again.

Actually, Ken, you could still manually bunt the thing over with the stick.
Can't think of why anyone
would. The AAI redesign does seem to eliminate power pushover (the most common
cause of
bunting), and reduces the divergent pitch-recovery mode that leads to PIO (the
next most common
cause). It also takes out that long slow oscillation that RAF's have.

I have been following the AAI thing for a while... spent a couple hours with Jim
Mayfield at
Mentone... spent more time at Fondy during OSH... flew it slightly (not much).
The demonstrators
they have been using are not their new gyro but modified RAF's like yours.
Theirs is going to have
a slightly larger cabin as well.

I have a big story I'm working up on the whole AAI vs RAF thing... RAF is
demoralised, and many of
their dealers have bailed. But others are standing by out of loyalty. It's kind
of a mess.

RAF's answer is a sort of a trim vane mounted to the rotor mast, behind the
cabin. They call it the
Rotor Stabilator. Seen it?

cheers
