Yesterday I did some work on the elevators by myself. This involved getting the perimeter of the right elevator pinned in place and then measuring the length for the ‘cross-braces’ making up the internal structure of the elevators and getting them cut and pinned in place out of 1⁄4” x 1⁄4” balsa stringers.
The length of the stringers from small to large are 21⁄8”, 23⁄4” and 31⁄4”.
I was surprised by the looseness of the fit. It’s like they didn’t take into account some light sanding of the laser cut joints where glue would be applied.
