7. Use a metal saw or a high-speed rotary tool with a

reinforced cut-off wheel to cut 5/16" from one of the bolt-on
axles. Mount the axle to the landing gear with a nut.

❏ ❏

8. Use a #11 (or 13/64") drill to enlarge the hole in the

wheel.Temporarily slide the wheel pant, a wheel collar and a
wheel onto the axle. Determine where the set screw for the
second wheel collar that holds on the wheel will be positioned
on the axle. Remove the wheel and pant, then file a flat spot
on the axle for the set screw in the wheel collar.

❏ ❏

9. Mount the wheel and pant to the axle with a wheel

collar on both sides of the wheel. Temporarily tighten the set
screws in the wheel collars.

10. Return to step 1 and mount the other wheel and pant

to the left landing gear the same way. Be certain to make a
left wheel pant.

11. Mount the landing gear to the fuse with six 6-32 x 3/4"

screws. Mount the tail wheel to the tail gear wire with the
wheel collar and set screw.

12. Place the model on its gear on the workbench. Prop-

up the tail until the fuse is level. Adjust both wheel pants so
they are level with the workbench.

13. Without moving the wheel pants, mark the locations

of the holes in the landing gear onto the wheel pants.

14. Drill 1/16" holes through the pants and the wheel pant

mounts at the marks you made (it may be easier to remove
the landing gear from the fuselage for this).

15. Fasten the wheel pants to the landing gear with 

#2 x 3/8" screws. Remove the set screws in the wheel
collars, and add a drop of oil to the axles and the wheels.
Add a drop of threadlocker to the set screws, install them
into the wheel collars and securely tighten.

Refer to this photo while finishing the cockpit and
gluing in the pilot.

1. Paint the inside of the cockpit black. Caution: Most

types of paint will soak through the balsa and show through
the covering. To avoid this, first clear-coat the inside of the
cockpit before painting it black.

2. After the black paint inside the cockpit fully dries, apply

the instrument panel decal.

Finish the Cockpit
