Rock,

I'm flying a World Models Intruder with its adjustable incidence stabilizer. Set the initial incidence with an incidence meter... then needed a good bit of elevator to fly straight and level. Started tweaking the stab incidence by cranking in more negative (Stab LE lowered) incidence. Finally got the airplane to fly straight and level without up or down elevator (actually, there is a slight amount of down trim that requires a little up pressure on the stick, that I like to fly with). Now the airplane needs a lot of down elevator to fly straight and level inverted. Balance point is where it's supposed to be, just a tiny bit forward of the main gear wheels. I'm out of ideas.
