❏
1. Unroll the plan sheets. Reroll them inside-out so they
will lie flat. Place the fin/rudder portion of the fuse plan over
your flat building board, then cover it with Great Planes Plan
Protector or waxed paper so glue will not adhere to the plan.
❏
2. Build the fin and the rudder from two 1/8" x 1/8" x 24"
[3.2 x 3.2 x 610mm] balsa sticks. Hint: When cutting the
“ribs” (the horizontal sticks), start with the longest ones first.
If you accidentally cut one too short, use it for the shorter rib
above it, thus minimizing wasted material.
❏
3. Remove the fin and rudder from the plan. Use a bar
sander with 150-grit sandpaper to carefully sand both sides
of the fin and rudder flat and even. Round the corners as
shown on the plan. Refer to the Expert Tip that follows, then
round the leading edge and top of the fin and the trailing
edge and top of the rudder.
❏
4. Sand a bevel on the leading edge of the rudder as
shown in the cross-section on the plan.
❏
5. Use a #11 blade to cut the notch in the rudder where
shown on the plan for the laser-cut 1/16" [1.6mm] plywood
control horn. Glue the control horn into the notch on the
left side of the rudder. Note: Use a pin to enlarge the holes
for the pushrod, if needed.
❏
6. Build the stab and elevators from the four 1/8" x 1/8" x
24" [3.2 x 3.2 x 610mm] balsa sticks. Do not join the elevators
with the 1/8" [3.2mm] dowel until instructed to do so.
❏
7. The same as you did the fin and rudder, sand the stab
and elevators flat and even, then round the corners where
shown on the plan. Round the tips of the stab and elevators
and round the leading edge of the stab and the trailing edge
of the elevators. Bevel the leading edge of both elevators as
shown in the cross-section on the plan.
❏
8. Pin both elevators to the plan. Make the elevator
joiner by trimming the 1/8" x 3" [3.2 x 75mm] hardwood
dowel to the correct length. Use medium CA to securely
glue the elevator joiner to both elevators.
❏
9. Remove the elevators from the plan. Use a #11 blade
followed by a bar sander with 150-grit sandpaper to bevel
To round the edges of the tail pieces, place one of them
on your workbench so the edge you are rounding extends
just beyond the edge of the bench. Use a bar sander to
hold it down. Use another bar sander to do the sanding.
