Paul,

 Do you have a picture of the 2 Powersport powered RV's that were
 featured at Oshkosh a few years back?  They also competed against Lyc
 powered RV's for an article in Kitplanes I  believe.

 Chris Cosman

 Yep.

Wasn't there some problem with the way they ran the test?

Chris

Yes but I forgot the details. If it is real important I can look it
up. something to do with setting the prop RPM to favor
the Lycoming.


Paul Lamar

I think I have it somewhere.  I'll address it if it comes up.
Thanks for the detour.  By the way, we just flew our new plane, it's
not the fast one we started a decade ago (wow how time flies), but
this allowed us to spend time with the kids.  We'll start on the fast
one again in a year or so.  Pix for your enjoyment:

By the way, someone asked a wingtip question a few days ago.  The
sheared wingtips, that is, wingtips that reduce chordwise in size but
still maintain the actual airfoil shape are all the rage these days.
That's what we did on this design.  It has a Riblett airfoil and we
can't seem to get a real stall out of it.  I can mush along nose high
power on at 26 indicated, not losing altitude, all day long.  The
motor is Continental A-65.  We would have used a single rotor if one
had been readily available.

Chris Cosman

Congratulations Chris. A real cutie.
