the props to which I was referring were the new blended airfoil props.
Hartzell has them STC'd for a lot of planes. They just don't have one for=20the
Beech Travelaire. That's the plane that has the IO360B1B in it that I want to
use on a Cheetah. If the prop were already certified for the engine, it
would only take 5-10 years to get it STC'd for the Cheetah, intead of 10-20=20years
for the whole process. {tongue-in-cheek, but you get the jist of it. The
FAA isn't hear to make flying safer, they are here to make it more expensive.}

<gasp> Gary,
Are you suggesting that the FAA is the government equivelant of the
(insect) tick???
On the prop issue, MT does have a newer scimitar blade design. I've not
seen the specs, and don't know if they plan on offering it on the
electric hub, but from the picture on the website, the airfoil appears
to be more modern.
One other advantage of the constant speed prop is that on final
approach, where the pilot pushes the prop into flat pitch (or with the
MT, toggles it to flat pitch) in the event of a go-around, drag goes
up. The blade is at fine pitch, presenting the most surface area to the
wind. Perhaps with 3 blades, some of the floating aspect of the Tiger's
landing characteristics on a hot day can be eliminated. Not that I've
ever had a Tiger float on landing..........

You're probably right. Very frustrating. And if they make it expensive
enough all the little guys will just quit flying certified planes and they
won't have to be bothered with us anymore. They can just spend all their
time with the airlines, part 135 operators and approved repair stations,
which is just about what they are doing now. The EAA and the homebuilt
movement will become even bigger. Just wondering, what is the advantage of
owning and flying a certified plane anyway?
