Does anyone know what this is?
I'm assuming it's a rudder part, given the "R-" nomenclature, and it came with the empennage. I believe it was in the "plates and gussets" bag (don't have the bag number / inventory list in front of me).
I've re-read the construction manual (pp. 6-3 - 6-5), and studied the drawing (DWG 7), and I just don't see it.
I'm past the rudder, and I'm a little concerned I missed something.
