John,
I did try Jim's Aymar Demuth prop and it gave me 170 MPH TAS at 7.5 gph
which is quite good. True - 170 Knots would have been much better, but then
I would have never returned Jim's prop {:>).

Rusty; I guess the old recollecter isn't what it used to be, as tonite I
was looking back to last April, and an e-mail from Jim Mosur stated the
prop
he has for a backup is an Ivo and not a Warp Drive. Some one else must
have
told me about the Warp Drive. Jim had an Aymar Demuth 68x74 that Ed has
tried, Jim stated this prop was good for 170 knots on 7.5 gph, which is
quite respectable. In the Sport Aviation Mag there are 3 props listed as
ground adjustable props, Ultra Prop, Powerfin and Props Inc. I don't have
any knowledge of these other than the fact that they are listed under the
props in the classified section. JohnD
