25. Roughen the area in the wheel pant where the
plywood blocks are to be mounted. Wipe the area with
rubbing alcohol. After the alcohol has dried, glue the blocks
into the wheel pants along side the groove for the nose
gear wire.
❏
26. Lay the wheel pant on your workbench with the
grooved side facing you. Locate the nylon landing gear
strap and position it on the wheel pant, making sure it lays
over the groove in the pant and that the holes for mounting
it are aligned over the blocks inside the pant. When you are
sure it is properly positioned, mark the mounting hole
locations on the wheel pant. Drill a 1/16" [1.6mm] hole
through each of these marks.
❏
27. File a flat spot on the bottom of the end of the nose
gear wire. Partially slide the wheel pant onto the landing
gear wire. Slide a #6 flat washer over the landing gear wire
followed by the wheel. Insert a 6-32 set screw into a 5/32"
[4mm] wheel collar (use a bit of thread locking compound for
this). Then, install the wheel collar onto the end of the nose
gear wire to hold the wheel to the nose gear wire. Use two
#2 x 3/8" [#2 x 9.5mm] sheet metal screws to attach the
landing gear strap to the wheel pant and nose gear wire.
❏
1. At the wing center-section on the bottom of the wing
locate the cut outs for the landing gear. Cut the covering
away, revealing the plywood mounting plates. Seal the edges
of the covering with your covering iron. Apply thin CA to the
wood and allow it to cure. This will fuelproof the wood.
❏
2. Place both landing gears in place on the plywood
plates. Drill a 5/64" [2mm] hole through each of the
mounting holes in the landing gear. Thread a screw into
each hole, and then remove the screws. Harden the holes
with thin CA. Then, mount the gear to the plate with four #4
x 1/2" [#4 x 13mm] sheet metal screws.
❏
3. Locate two bolt-on landing gear axles. The axles need
to be shortened. Cut each axle to a length of 1-1/4" [32mm].
❏
4. Bolt an axle to each landing gear with a 5/16"-24
[8mm-24] axle nut.
❏ ❏
5. Place a piece of masking tape centered on the left
side of a wheel pant. This pant will be mounted to the right
landing gear.
(Note: When doing this for the wheel pant on
the left landing gear, the hole will be made on the right side
of the wheel pant). Measure the opening in the wheel pant
to find the exact center. Draw a line on the masking tape
indicating the center of the wheel pant. Measure up from the
bottom of the wheel pant 1/2" [13mm] and mark another
line. Drill a 5/32" [4mm] hole at the intersection of the lines
through the side of the pant. Do not drill through the outside
of the pant.
