The wing should be +3.4 degrees, the boom -6.1 degrees (ref), and the horiz. stab. -4.8 degrees. This is reference information only. This may or may not apply to a Firestar. I would pester Kolb again and see if they can give you some information. If you know someone nearby with a good flying firestar maybe they will let you get the information yourself. By the way, the difference in my wing angle from the "measured" set up to what Brian recommended was about 3 degrees.

That seems like a whole lot to me, but I do not have an aero engineering degree. What I believe I do know from researching Kolbs for a while, is that different models of Kolb aircdraft had different angles, and these LOOK like theyw ere changed around from one model to another in order to meet a certain mission, or achieve certain speeds, etc. For example it looks to me (from the various photos) that the Slingshot was designed for a higher speed range, and the wing/tail angles were a lot lower. I also be lieve that this was accomplished by the hole drilled in the wing spar attach fitting at the root. John H can you shed some light on this, as to whether different Kolbs had different wing angles, and what the reasons were for these changes?
