I am not even close to choosing a propeller, but I am a bit surprised
by the varied opinions on this subject. I would think the design of the
propeller would rank only second in importance to the wing itself, and
that the prop should be carefully chosen or custom made considering the
airframe, engine and speeds.
We go through significant measures to reduce airframe drag, and worry
about every extra ounce of dead weight during construction, a prop
efficiency variation of just 10% would seem to take away all those
factors.
I hope you guys have this prop debate all sorted out by the time I get
to it :-)
