Step 23
Use the radio system to move the gear to the “down”
position. Insert the strut into the retract mechanism and
secure it by tightening the screw using a 3mm hex wrench
or ball driver. There is a flat area the screw secures to. This
will align the strut so the aircraft tracks straight on the
runway without excessive wandering.
Step 24
Use the radio system to move the retract mechanism to the
“up” position. Check that the wheel is centered in the wheel
well. It may be necessary to adjust the position of the strut
in the retract mechanism slightly so the wheel is centered.
Step 25
Position the gear door as shown in the photo. Use a small
drop of medium CA to temporarily tack glue the gear door to
the gear door mount. Make sure not to get any CA into the
threads of the gear door mount. The CA only needs to hold
the gear door in position so it can be marked to drill the two
holes for the gear door mounting screws.
Step 26
Use a pencil to trace the outline of the gear door mount on
the gear door.
Step 27
Carefully remove the gear door from the gear door mount.
Use a pencil to draw a center line through the tracing of the
mount as shown.
Step 28
Measure in 1/8-inch (3mm) from each edge of the gear
door mount outline and draw a line as shown. The distance
between the two lines will be 19/32-inch (15mm) if done
correctly.
Step 16
Remove the wheel cover from one of the main wheels.
Step 17
Check to make sure you have selected the correct strut for
your particular wing panel. The scissor mechanism will face
to the rear of the aircraft and the flat area on the gear door
mount faces out away from the wheel well.
Step 18
Use a 1.5mm hex wrench or ball driver to loosen the
setscrew that secures the axle to the retract strut. Remove
the axle from the strut assembly.
Step 19
Slide the wheel collar from the axle. The axle will now fit into
the hole in the wheel. Make sure to install the axle into the
side of the wheel with the deeper recess that does not have
the screws that hold the wheel assembly together.
Hint
: Apply a small drop of machine oil on the axle to
allow the wheel to rotate smoothly.
Step 20
Slide the wheel collar on the axle. Secure the collar using a
2mm setscrew. Make sure to use threadlock on the setscrew
to prevent it from vibrating loose.
Step 21
Slide the axle back in the retract strut. Note that the wheel
will face opposite the flat area on the gear door mount. Use
a 1.5mm hex wrench or ball driver to secure the axle in
position. Make sure to use threadlock on the setscrew to
prevent it from vibrating loose in flight.
Step 22
Snap the wheel cover back on the wheel at this time.
