Europa-List: propeller optimisation

[Graham Higgins <ghiggins@nsw.chariot.net.au>]

Interested in this line of discussion. I am still attracted to the idea of 
reverse thrust braking, but could not justify the cost of changing from 
Airmaster/ Warpdrive on this basis alone. However, if there was significant 
gain in performance in cruise, and perhaps better cooling on the ground ??? 
tempting.
My question to all is  Do we have better choice(s) today? Is there any good 
information to assist that choice, or are we all just guessing?
