Install The Main Landing Gear - GREAT PLANES Piper J-3 Cub Instruction Manual

❏ 2. Cut a slot in the tail post of the fuselage 3/8" [9.5mm] up
from the bottom of the fuse for the tail gear bracket. Coat the
tail gear wire with petroleum jelly where it slides through the
bracket. Glue the bracket into the slot using 30-minute epoxy.
❏ 3. Hold the rudder to the fin next to the tail gear wire (or
tape the rudder to the fin). Mark the rudder where the arm
portion of the tail gear wire will enter.
❏ 4. Cut a groove in the LE of the rudder and drill a 3/32"
[2.4mm] hole where you made your mark to accommodate
the tail gear wire. Hint: Use a 3/32" [2.4mm] brass tube
sharpened at the end to cut the groove. (The Groove Tube
Grooving Tool (GPMR8140) works great for this task.)
❏ 5. Test fit the rudder to the tail gear wire. View the rudder and
the tail gear wire from above (when the fuselage is upside-
down in your cradle). If necessary, bend the tail gear wire so
your model will taxi straight when your rudder is centered.

Install the Main Landing Gear

❏ 1. Use a fresh #11 blade to trim the covering from the slot
in the fuselage for the main landing gear.
❏ 2. Test fit the Main Landing Gear. It's helpful if you use a
file to remove any burrs or sharp edges from the ends of the
wire. Seat the landing gear wire in the landing gear rail on
the fuselage. Use a Nylon Landing Gear Strap as a guide
to drill 1/16" [1.6mm] pilot holes for the screws. Secure the
landing gear with two nylon straps and four #2 x 1/2" Sheet
Metal Screws.

❏ ❏ 3. Position the landing gear fairing mounts on the landing
gear fairings as shown in the photo. The hinge line of the
mount must align with the edge of the fairing. Mark the
location of the mount and remove the underlying covering
from the fairing. Use 6-minute epoxy to glue the mount to the
fairing. Make both a right and left gear fairing assembly.
