Thanks Tim,
Getting locked out might have the up side in that I might finish my Europa !!

I spent 14 years from the right seat and enjoyed it very much.

have a lot of building to go before I have to worry again. I'm nevertheless
wondering if more learned people would care to comment on whether a fixed pitch
prop, maybe a Catto prop, could work on a 914. I know the pitch of the prop
would need to be determined to suit the style of flying I prefer, and lets
say that is to go as fast as my engine/airframe combination will allow, at 75%
power. To that end I reckon my takeoff performance will be compromised, but
recent
video of Bob Catto speaking makes me believe it might only be in the order
of a couple of hundred feet. If I can deal with that, well what other
limitations
are there that haven't come to mind yet? Does anyone know of a builder
of anything that has strapped a fixed pitch prop to a 914? I don't and thats why
I'm asking. There might be a bunch, I just don't know them. Also, there might
be some issues at altitude, although simplisticall!

think there is probably even issues of aerodynamics that might be wrong with
that last statement, so I'm happy to read whatever someone can contribute.
