Can anyone help me specify a propeller for the Tailwind so that I can
give good info to the prop maker. I am thinking about contacting
Craig Catto about building the prop,  but I don't know enough to make
an intelligent inquiry.    Here is what I have.  220 hp at 2750 prop
rpm.  The Tailwind  can easily achieve 250mph as we have done this
repeatedly going down hill so cruise will be someplace between 220
and 240 mph.   I don't have the numbers but the frontal plate is said
to be the same as an RV-3.  So, how long should this two bladed prop
be?  Typical, 0-320 Tailwinds use  68  to 70   inch props.  What
about pitch?   Catto comes highly recommended  but I have not seen
his work.
