RE: Build Thread-Scratch built for 8s
The wing tube is 22mm CF tube I got at a LHS, and then I made my own FG sleeves. Next I glued in the aileron sub ribs using a 1/32” shim. Then I stick an x-acto knife through the sheeting in several spots to mark the location to be cut out later. The next two pictures show the aileron hinge line knockouts in the ribs. The last shot is of the aileron hinge spars, and control horn hard point.
