Default RE: 40% Extra 300 Construction by-the-numbers

The lite ply plate doubler, plus adding the filler piece in should be approximately 2X as strong as just the root rib, plus the kit pieces are laser cut. I could not get another set of root ribs cut/drilled as accurately. This really is the straightest kit I've seen. I could not detect anything out of alignment, or even the slightest warp in the wings, stabs, or rudder. I'm almost afraid to do the finishing sanding on the wings and stab to mess up the perfect surfaces.

A disclaimer. I do not recommend these wing modifications from the standard kit under normal circumstances. I am testing to see if this will make a great flying airplane even better. The only place I expect to see a difference is in the 1 roll circle and rolling loop maneuvers.
