Well, my new prop is complete and I flew it this morning.
The performance was disappointing :(
But my oil temp is down :)

I won't bore the whole list with the details, but those who are

Sorry to hear that Perry. You have put in a lot of years
of hard work into ducted fans. What's next?. A PSRU and
conventional prop  or a lot more horse power?

If you read my page, you can see where I'm heading next.  I'll
fly it like this for awhile, but looks like a duct with less
acceleration may be a good idea, which I think is what you were
recommending anyway (a duct more like the Prescott pusher guys
are using - a straight through approach).  I was a little extreme
with the current one, trying to maximize mass flow.  That apparently
isn't the whole answer.  An interesting experiment though.  Every
experiment is a learning experience.

Sure, everyone could use more HP.

It does fly, as well or better than a 172.  I flew a 150 with
just me in it a few weeks ago - 400 fpm climb.

When I decide to get into racing, I'll put that gearbox on :)

Ducted fans won't work on my next homebuilt airplane project,
so I guess I'll have to go the same path you're going on that
one (gearbox), but it will still be (dual) rotary powered.

Right now too much pitch sounds like the major problem.
You need to get that engine going 6000 RPM or more in stright
and level.
What top speed and RPM are you seeing Perry?
