Greetings!

I have a "favorite way" to change the incidence. After determining which way and how much to go, this method will give you a new and solid wing saddle, but in a slightly different position relative to the stab.

First, make a couple of shims from a balsa stick that will prop the wing up to where you want it, and tack the shims in place on the fuselage with CA. Then cover the wing with Handi Wrap (thin plastic film) and bolt it into place. Then mix up a batch of 30 min epoxy and micro balloons, about 50% each. Fill the gap between the wing and the fuse with the mixture and smooth it into a fillet with your finger. When dry, pop the wing off and sand the rough edges of your new wing saddle to shape. Works great!
