Empennage: Elevators. Outboard trailing edges tapered.

The plans call for the outboard edges of the elevator trailing edges to be sanded down, providing a taper to transition between the different thicknesses of the wedge itself and to the elevator tip fairing.  I had just recently purchased a belt sander for this and other aspects of the build.


The left elevator taper didn't turn out as good as the right side, no doubt owing to the fact that I did the left one first.   Here are a few perspectives on the left side.  Not perfect.  Almost a bit of a twist was formed owing to the asymmetry of each side's taper.  But it will do (it's a sort of Catch-22 in that once you're on this trajectory, the more you fix it, the worse it gets).


When the left side is laid across an untapered trailing edge, you can see how it compares.


Now, for the right side.  I did a much better job on this side.


With the right side adjacent to the rib fairing, I think the taper will be okay.
