7.
Press the aluminum tubes into the wheels. And slide the wheels onto the landing gear wire.
8.
Slide the star lock onto the wire to hold the wheel in place. You want a little room for the wheel to move, but not too loose. Secure
the lock in place with a drop of CA. Hit the drop with CA accelerator immediately to keep it from going into the wheel bushing.
9.
Set the fixed gear assemblies aside in a safe place and continue to the next section.
SANDING:
1.
Lightly sand the fuselage with fine sandpaper. Be careful around the stringers.
2.
Lightly sand the wing with fine sandpaper. Make sure to sand W22 at the top center rear to match the ribs to each side of it. That
way the wing fits properly to the fuselage. Be careful when sanding around the stringers.
3.
SAND the leading edge of the wing to match the contour of the top and bottom of the ribs. Round off the very leading edge to
finish the airfoil shape.
4.
Sand the aileron so the A7 part matches up with the top profile of the ribs and the bottom of A6.
5.
On the stab and elevator parts, round all the outside corners.
6.
On the vertical fin, round the outside corners. On the Rudder, round the outside corners. Sand the balsa pieces where the control
horn goes through to a nice bevel shape as shown in the image below. Sand a bevel on the rudder as shown in the image below.
There is an engraved line down the center to help you sand to the proper place.

RETRACT INSTALLATION:

1.
If you are using fixed gear, you can skip this section.
2.
Bend the landing gear wires as shown on the plan sheet. Make sure you make a left a right, as the landing gear wires have a flat
ground for the set-screw. MAKE SURE you get the distance from the end that goes into the retract unit to the first bend correct!
Leave a little extra on the end that goes through the wheel. You will finish trim it later.
3.
Press the included bushings into the wheels. Slide the wheels onto the landing gear wires.
