Hinge line wing, aileron and flaps.

The aileron and flap cut out of the wing very nicely. I used my chop saw totrue up the ends and faced them with balsa.

So I like to sand, it is a Zen like process. The built up hinge line changes this concept. Really glade I went with 3/32 instead of 1/16 balsa for the sheathing.

I started by rounding off the aileron and flap. I marked the center, the radios and the outer line fir reference. I used a razor plane to get it close then I used a sanding T bar to get it close.

I ripped down various <span style="color: #366388">PVC pipe</span> in halve, 1/2, 3/4, 1, 1-1/4, and 1-1/2, and applied adhesive sand paper to theses sanding blocks. This is a good <span style="color: #366388">finishing touch</span> to get a perfect radius.

Next I glued triangular balsa to the wing hinge line. Using my dremel and a drum sander I carved it down checking it with the PVC sanding blocks. I applied sand paper to the aileron and finished sanding with the flap and aileron to get a perfect fit. It takes a lot of work to make this type of hinge line but it is well worth it. I am currently working on the elevator to complete all the control surfaces.

I cut in all the servo bays and made the gear covers out of 1/16" ply. Started to glue in the formers and block on the fuselage. Next finish the wing, tips and cut in the spar.
