Yep, I measured it as soon as I got home from work today. It is plus 1/2 degree, so we have decided to leave it alone for now. I must say I am surprised at needing down angle on the engine. Can you elaborate a little on why this would lower the tail and reduce the need for up elavator? I would think that down thrust would tend to raise the tail and that's what we are trying to avoid. We are working towards lowering the tail for less down force on the elevator. You are right about being able to adjust it easier though. I can add a small washer to the top mounting screw on the engine and get a little down thrust.
