1. Remove the tailgear wire from the rudder and place its

leading edge on your work surface. Use a pen, laying on the
bench, to mark a “bevel to” line on both sides, approximately
3/32" [2.4mm] high.

Note: You may need to adjust the height of the rudder with
card stock so your “bevel to” line is not too high.

❏

2. Using the “bevel to” lines and the centerline as a guide,

shape the LE to a “V” shape using a razor plane or the Great
Planes Multi-Sander (GPMR6190) with 150-grit sandpaper.

❏

3. Use the same procedure to bevel the LE of the

elevator.

❏

4. Lay the rudder over the plan and mark the cutout on

the LE for the elevator joiner. Use a razor saw or hobby knife
to cut the LE for the elevator joiner.

❏

5. Temporarily attach the rudder to the fin and the elevator

to the stab using the CA hinges and set them aside.

❏

1. Cover the center wing panel plan from W-4 to W-4 with

waxed paper or Great Planes Plan Protector.

❏

2. Match two of the 3/16" x 3/8" x 18" [4.8mm x 9.5mm x

457.2mm] basswood main spars so any warps will
counteract each other.

Finish the Tail Surfaces

Use the sharpened tube to carefully gouge the leading
edge of the rudder. You’ll have to make several passes to
make the recess deep enough for the tailgear wire.
