Kevin, I'll move this to the top. The conversion improved everything.

Ken, thanks for all and I will definitely nose about the rotorcraft forums.

Thanks to Bill also

My personal opinion, based on my understanding of the aero involved and reading
what Glasgow
has published, is that centerline (centre-of-mass) thrust is more important than
the stab both in
preventing PPO and PIO. But both are important.

You can fly a gyro without knowing theory, I think, but God help the pilots who
fly a machine that
was designed without theory.

cheers
