Rudder and Elevator
First remove all balsa parts from the 3mm balsa sheet, then align the vertical
tail fin and the vertical tail rudder and tape
them together with masking tape. Give both
ends a light sanding before gluing the top and
bottom tip to the vertical fin. Do the same with
the Elevator. All tips (Rudder and Elevator) are
slightly longer than needed. Glue them flush
with the leading edges of the rudder and
elevator. After the glue dried you can sand the
overlaying parts of the tips flush with the trailing edges of the rudder and
elevator.
Now cut a piece in the length of the milled slot in the elevator from the 200 x
2.9 x 4 mm carbon strip and press it into the slot (vertically) and glue it in with
thin super glue. Next dry fit the 3mm plywood inlet for the elevator mounting
screw (the edges may need some light sanding). When you have tight flush fit
you can glue the inlet into the elevator.
Carefully sand the elevator from the hinge line to the trailing edge to get a
'sharp' (1.5mm) trailing edge. To have the elevator mounting screw (2.9 x 18
mm) as flush as possible with the elevator bevel the inlet a tiny bit.
As a last step cut the elevator along the hinge line in two (do not cut through
the tips!) and sand an angle into the moving bit allowing a down elevator
movement of 10mm.
