Re: flat plate area

Jon Finley <finley@...>

I certainly don't disagree but would add that IMO, the largest drag
producers on the Q designs are the wing/fuselage junctions and the
wheelpants. Those items alone, IF they are as bad as I believe, are enough
to make the flat plate area look rather large. Remember, Mike has these
areas perfected (or at least as close as is possible) on his AR5.

0.4 would be nice thats for sure. The lowest one I have heard about was
Mike Arnolds AR5 with a claimed 0.88. The AR5 is slick but its actually
huge compared to a Q1 or even a Q2.

Yup the Q1 should be under that by a bunch. It's smaller (that helps a
it has a square fuse section, teenie, tiny wind up rubber band onan...etc
etc ;-]
If the general opinion was that the prop on the Onan was crap, then I
the Q has got be down between 0.85 and 0.95.
