Tony that's how I was taught.

Hi
Put the plane in a foam plane cradel
Put a level on the sab and MAKE the stab read ZERO on the level - (dead center on the bubble)-shim it so it stays there
Now put your incidence meter on the wing (radio on if you have the meter placed on the ailerons )
The reading you get on the meter will be your wing incidence ( always with regard to the stab that is ZERO )
In this case the meter sb reading 2.5 degrees positive if correct
That means the wing sb 2.5 degrees higher at the leading edge than the trailing edge
You need to adjust the wing seat as needed to have the wing at 2.5 degrees positive location if it is not there already
Be sure to use your means of fastening you wing downthe incidence must be the same after all is tightened
This is a very good time to check your wing to be sure it is centered on the fuse
I use a piece of nylon fishing line with knots in it
Example lace one end of the nylon line at the end of the aileron (closest to the wing tip ) and extend it to the joint between the stab an rubberdo the same thing to the other side of the wing
When both lenghts of line are equal the wing is centered put a mark on the fuse so you can always have the wing square to the plane every time you install the wing on the plane
Building and flying more than most for 26 years
This sb the info you need to know and how to get there
