Scott,
Way to go! I know how exciting my first solo was, and I can't imagine what it
would have been like in my own hand built airplane.
Congratulations from Virginia!

When people ask how long it took to build GHTF my answer is "I'm not
finished." I'm just flying it now while I keep working on it. One
day if I finish cutting new holes, and changing things and get it
where I like it, maybe I'll finally spend some time to make it look
'purdy' ... Right now it's just bare aluminum (no polish or wax) ...
poor thing.
But it's a testimony to Chris Heinz' basic assumptions that 1/ you
don't have to be a craftsman to build his aircraft. 2/ it's a fine
flying little machine even when built by a raw beginner non-craftsman
like me... 3/ and once the bare aluminum dulls in the weather, it
doesn't Need much more than that for exteriour finishing. But of
course one day I'd love to get a really bright paint job of some sort
on it.
For those wondering what to expect when finished and flying the HDS,
here are some numbers I recorded during a short test flight this
evening, June 20th at Qualicum Beach (CAT4). I was zeroing in on
endurance speed and trying to see how little power I could use to
maintain level flight. Turns out to be less than I originally
guessed. And I couldn't find much of a "slow flight" envelope if you
use the official definition of slow flight (i.e. on the backside of
the power curve).
The airplane handles very smoothly right down to the stall burble -
very easy to control. I'm starting to get happier with my landings -
I've only got 63 hours on the plane since first flight in July 2001!
stuff happens.... I call it my brand new seven-year-old plane.
June 20th 2008 At 16=B0C; 2,500 feet; 1060 lbs (just me and 1/2 fuel)
Warp Drive 3 bladed composite tapered 70=93 dia. @ 16.5 degrees at tip.
prop / engine rpm (prop rpm rounded to nearest 100)
2200 / 5,300 = 120 mph (max continuous cruise power limit)
2100 / 5,000 = 110 mph
2,000 / 4,800 = 105 mph
1,800 / 4,400 = 80 mph
1,600 / 4,000 = 70 mph
1,500 / 3,700 = 60 mph
1,500 / 3,700 = 50 mph on verge of stall in level flight! cool
