NOW cut your hinge lines and cap everything on the fin and stabs.

There's nothing special to mention here, except use a band saw or scroll saw, with the piece laying in the bottom shuck so it's level, cut slightly outside of the line, and sand TO the line.

On the elevators, remove the inboard corner and install a solid piece of balsa (contest grade please.) After it dries, sand it all flush, and cap everything with good qquality (LIGHT) contest grade balsa.

Once everything is dry, mark center lines down the hinging surface of your fin and your stabs. If you don't have a tettra tapered hinging tool, I suggest you get one. Central carries them.

We'll mess with the wings later....now on to the fin.
