I borrowed an incidence meter and found that my rear stabilize has between 1.5 and 2 degrees of 'up' built into it; the wings are close to 0, and the engine is about 1.5 degrees down (supposed to be 2 degrees).

What should I change? The plane likes to fly UP, and uses lots of down trim to fly straight. I know I can add a washer under the top of the engine mount to add more down thrust, but not sure (haven't thought too hard about yet) how this would affect everything else. Obviously I can't change the incidence of the elevator as it's epoxied in place. The tail was able to be repaired with minimal amounts of CA and epoxy, so it's not going to be removed.

Thanks.
