Kitfox folks, my Model II, rotax 532 with GSC fixed pitch prop is now
flying, after a long dormant period. After being purchased from Denny in
1990 is sat in a barn in Arkansas for 18 years (the owner died) before I
started construction in April of '08. It is all built per 1990 instructions
excepting the leading edge of wings. I used the McBean plastic extrusion
and covered the upper surface 12 inches behind that with .016 aluminum from
ACSpruce, eliminating the scalloped shape. It came with 2 six gallon alum.
wing tanks which feed a round alum. header tank which I opted to place
behind the copilot seat.
It flies great, jumps off the runway in about 100 feet and climbs about 900
fpm at 800 lbs. I put a GSC sport EFIS in the panel to handle all flight
info without vacuum. It also gives me map, airport data, terrain and
"highway in the sky" approaches. After two hours flying, I still can't
digest all the info its giving me. It cruises at 75 mph at 5500 rpm and
tops at 88 mph. I still need to add fairings to the jury struts and landing
gear, and wheel pants would help too.
Many thanks to the McBeans for advice and support, and many others on this
list who have answered questions and offered tips. As one guy said, "plane
is flying and now tinkering begins". I got some home made floats from Kasper
in Canada, and plan on installing them sometime next spring. Then finishing
his retract system which is actuated by compressed air. That promises to be
fun. Anyone flying in DFW area let me know and we will fly together. My
plane on the trailer lives in my garage. Maybe I will get to Sun n Fun next
year. Next project, start saving so I can buy a New super sport from KITFOX
LLC.
PS, anyone have wheel pants for 18 inch wheels for sale?
PPS My GSC prop is a 10 degree climb prop. The guy at GSC said I could
ream the holes thru the roots a few degrees to make it ground adjustable.
Has anyone done that, and how many degrees would I want to add to make a
cruise prop?
PPPS I found that I need to budget an extra half hour at the airport to
answer all the questions from admirers--aint that fun?

Ed...Beautiful! Mine's a model 2 (ser # 707), 582, GSC prop completed in 1991. Only complaint is that I live here in South Dakota now and weather precludes the amount of flying I'd like to do. Lived in Dallas/Denton for many years during college years.
That leading edge mod looks nice, even from far away in the pics. Would definitely do that if I had it to do over again. That blunt front spar/leading edge that's standard is a big drag penalty.
My GSC prop was also fixed pitch (at) 10 deg. When I had it overhauled this year, I sent it to the factory. For $150, they beautifully restored the blades, balanced them, and feathered out the hole in the root of each blade for me so that it's now ground adjustable. Change from 10 to 11 degrees pitch gave me 5-7 mph faster level cruise (at) 4-600 fewer rpm and 100 to 200 degrees cooler egt's. It just sounds and feels happier. What a difference one degree makes.
Only other mod I'd recommend, especially in the hot Dallas summers, would be to make a couple of simple wooden standoff's to get the radiator out of the turbulent flow on the underbelly. I was pushing the red line on the coolant temp on warmer days before I did that one.
Happy Flying!
Chris

Congrats Ed, Can you post or send photos of the header tank installation
behind the seat and the plumbing please? I also use that tank in it's
original location and will want to move it to reflect current design.
Thanks.
