Hi Paul, My friend with the Velocity tells me that the fastest
Velocities have Ivoprops on them but they had problem with the earlier
versions with the IO360 4 cylinder but had no problems with the 6
cylinder Franklins.

I think your friend is mis-informed.
I looked when I went to the Jackpot NV races and saw no IVO's on any of
the airplanes. These are the fastest Canard airplanes in the world.
Most of the fast guys are using Klause's props. Klause himself is going
over 250 MPH.  

This is what real 236 MPH props look like.
