Moving right along to the bottom of the wing now and installing the fuel tank drain.
Pretty much the same deal as the fuel filler recess. Manual doesn't tell you anything - except where to drill. Hole size is 40mm for the outside and then I went quite a bit smaller inside - 25mm and then used the Dremel to elongate the hole where needed for the two drain holes. (see pic).
This is an easier job than the filler cap because of size and also access is a lot better - you can see underneath easily and work through the hole in the root end of the fuel tank. With the filler cap a little inspection mirror is needed.
After this job I installed the bearings in the Aileron bell cranks and drilled (Dremeled) the hole for one of the bell cranks. This hole will be covered in the end by a metal plate, but is necessary for installing the crank as both bearings that it will sit in are already installed inside the wing.
I may keep going with this one wing until it is done and then switch back to the other wing - we'll see.
