You're correct, Rusty....the winds were a direct
crosswind 20 knots, gusting higher (windsock
standing straight out).  At approximately 3:30 P.M. my SQ2000 slipped the surly bounds of Earth....made
a couple circuits around the airport and had an
uneventful (yawn) landing.  The precarious part was
the take-off and climbout.  I am not getting enough
power.  From 1/4 to 1/2 throttle, engine accelerates
smoothly and plenty of power. As soon as I try to go
above 1/2 throttle, the engine begins to bog down.
Advancing the throttle more only made it bog down
even more.  On takeoff roll, I was only able to get
4400 rpm's at approximately 1/2 throttle.
Acceleration felt OK, and the nosewheel lifted at
around 70 knots. Mains lifted off shortly afterward,
but it just didn't want to climb. (Flew fine in
ground effect, of course).  Unfortunately, I had
reached the point of no return (short runway) and
past the accelerate/stop point, so I was committed. Found a "V" in the treeline and headed for that. Made it...(whew)....continued slow climb to 2000
feet, made a couple of circuits around the airport
and had a smooth landing (considering the strong,
gusty crosswinds).  Down and stopped by mid field.         I had a few "bugs" to work out, like
tightening the tension on the nosewheel, so after 3
trips to the runway and back to the hangar, by the
time I got to the runway the fourth time, water
temperatures were up to 190 degrees.  Fortunately,
on climbout they started dropping, and by the time I
was downwind, they were stable at 170.  I am pleased
that the temperature decreased in the climb.        I have to work on the power problem ASAP. I'm thinking it is mixture related. I had programed
the MicroTech ECU to be 10 percent leaner (for all
throttle settings), and perhaps that was a mistake. If I remember correctly, you need sufficient air and
sufficient fuel to make power.  Because the
butterfly in the throttlebody continues opening past
1/2 throttle, I'm reaonably certain that I am
getting more air past 1/2 throttle. I am assuming
that I am not getting more fuel coming in past that
1/2 throttle position, causing the engine to bog
down past 1/2 throttle.  Best RPM I could obtain was
4400 rpm (in cruise with the prop unloaded), and
with a 2.19:1 gear reduction,that puts my max rpm on
the prop at only 2000. Barely enough to fly, let
alone climb out. Will continue problem solving and
pass on results.  On the positive side, first flight
was successful, aircraft flew well, and no-one got
hurt.  I have to count that as a success.  Take
care.  Paul Conner, Mobile, AL
