Hi Mark,

Thats exactly right on the incidence meter -- it doesn't (within reason) care about the angle of the fuz. You can have model sitting on its wheels and quickly check stab to wing relative incidence (or wing to wing etc.). Useful in the workshop, but also at the field when you are doing a solid few hours of initial trimming and want to keep track of adjustments you have made (particularly if you are chasing trim problems in circles as sometimes happens -- and definitely happens if you have wing and stab adjusters!!).

If something like the stabs are fixed at 0 degrees at build then that is what you set the meter on from then on. If stabs, wings and meter are all adjustable then you may sometimes need to go back to surface on the fuz (which the Impact doesn't really have -- so I used one of the paint lines)

You can do the same with the bar type meters with a 'level gauge' in the middle -- you are just wrirting down/remembering measurements and calculating differences -- and they have lower resolution.
