Hi Dale,
     Several years ago my friend at Independence bought a FlyBaby. He asked
me to help him make it fly better. It would fly level 75 MPH at 2300RPM and
power off stalls were "BAD" at 55MPH . And it took a lot of forward
pressure and about half left stick to cruse at the 75 MPH. We don't have
the planes so  I leveled the airplane using a carpenters level under  wing
root  rib. Then checked the left wing at the bottom of the last rib. It was
flat no twist or wash out. The right wing was washed in or had the leading
edge higher than the trailing edge. I readjusted the cables so that  both
wings have wash out (wing twisted down at tip) with level bubbles with a 1"
block on top of a 30" level at the last rib. To fly level at 90 MPH
indicated and 2150 RPM it was a little nose heavy needed just a little back
pressure. So I took out one turn on the turn barrels to relive just a
little of the wash out. Now it flies level 90 MPH indicated at 2150 RPM
hands off and power off stalls straight ahead at 35 MPH indicated. The
point is you can adjust the trim with wing wash out.
