Mount The Canopy Hatch; Mount The Landing Gear - GREAT PLANES EXTRA 330S Instruction Manual

Mount the Canopy Hatch

❏
1. Use a sharp hobby knife to cut the covering from the
four canopy hatch screw holes in both sides of the fuselage.
❏
2. Glue both 1/4" x 5/8" [6 x 15mm] hardwood dowels into
the front of the canopy hatch.
❏
3. Cut the covering from the four holes in the fuselage for
the canopy hatch mounting screws.
❏
4. Test fi t the canopy hatch to the fuselage with four 4-40 x
5/8" [16mm] Phillips screws and #4 nylon washers. Note: When
mounting the canopy hatch at the fl ying fi eld, use a small drop
of threadlocker on each screw so they don't loosen from engine
vibration. Threadlocker doesn't need to be reapplied every time
the cabin top is mounted, but should be applied as necessary
to keep the screws from coming loose.

Mount the Landing Gear

❏
1. Cut both 3/16" x 2" [4.8 x 50mm] axles to a length of
1-11/16" [43mm]–a rotary tool with a fi ber reinforced cutoff
wheel works best, but a metal saw could also be used.
❏
2. Slip a 3/16" [4.8mm] wheel collar followed by a wheel,
then another wheel collar onto one of the axles. Use a
fi ne-point felt-tip pen to mark the screw hole in the outer
wheel collar onto the axle.
❏
3. Use your rotary tool with a cutoff wheel or a metal fi le
to grind a fl at spot at the mark.
❏
4. Mark and grind a fl at spot on the other axle the same way.
❏
5. If you haven't yet done so, mount the main landing
gear to the fuselage with three 6-32 x 1" [25mm] SHCS, #6
lock washers, #6 fl at washers and a drop of threadlocker on
the threads.
❏
6. Use a 1/2" and 7/16" wrench to mount the axles to the
main landing gear with a 5-16/24 lock nut.
❏
7. Mount the wheels to the axles with a wheel collar on
both sides of each wheel. Secure the outer wheel collars to
the axles with a 6-32 set screw and a drop of threadlocker on
the threads. (The inner collars serve only as spacers, so no
set screws are required on them). Add a few drops of oil to
both sides of both wheels where they contact the collars.
❏
8. Mount the wheel pants to the main landing gear with
4-40 x 1/2" [13mm] SHCS, #4 lock washers, #4 fl at washers
and a drop of threadlocker on the threads.
❏
9. Spin the wheels to make sure they roll freely. Make any
adjustments necessary–if the wheels contact the edge of the
opening in one (or both) wheel pants use a rotary tool with a
sanding drum to enlarge the opening.
