I kept filling and sanding and refilling the top side until it was pretty good. Next up was working on the bottom. Pretty much the same endless task of sanding and filling, sanding and more filling.
I won't bore you with endless pics that look the same. I started doing the tips top and bottom too. I spent a lot more than 30 hours doing all this and I seemed to have it about right. Within .1 of a degree. Then I mounted the canard back on the fuselage and got different numbers.
The plan is to just continue on, finish fixing the canard attachment points, the tabs and so on and then have a final go with the level and more sanding. I think I have enough material (filler) on the canard top to get pretty close now without adding more.
