Here's what I did.
1 Set up the fuse with the sternpost clecoed in and checked everything
possible for vertical or horizontal ie The two main spar pin sockets
horizontal and the sternpost vertical.
2 Held everything jigged at that point, fuselage in its cradle, then
took the top off and set up the tailplane cross tube level and parallel
with the seat back bulkhead. IOW
parallel with the mainspar. I started with the left hand hole, lined up
the cross tube then cut the RH one.
3 Much later, starting filling and finishing of the fuse I filled the
stubs to match the tail with about 1/4 degree nose up elevator, a guess
really. Trim position will vary with CG and speed. I wanted reasonably
narrow gaps between stub and elevator to reduce drag.
