Final Assembly Continued
Motor and Gearbox Continued
55.
Slide the motor, big gear up, within the opening at the
nose
of the fuselage. Push the motor
back until fully seated within the recess cut to the motor mount plate. Ensure that the motor
is resting flat on the plate, then with a fine glue tip on your bottle of glue, reach in through
the “cowl cooling” holes on either side of the motor and tack glue the motor tabs with
medium CA. Do not apply too much glue as the motor should be free to “snap” loose in the
event of a less than perfect landing, preventing damage to the nose of the aircraft.
Wing Installation
56.
Cut the second length of provided 1/32 inch diameter wire in half then pass these pieces of
wire through the holes in the fuselage side where the wing will be mounted. These wires
will assist in aligning part W6 in the next step.
57.
Slide the
right
rib W6 over the wires and tack glue to the fuselage side. Repeat this process
for the
left
W6 rib applying it to the opposite side of the fuselage. Remove your alignment
wires and final bond the ribs with thin CA.
58.
Fit and bond the ply spar W7 to the slots in the fuselage sides and ribs W6. Note: Ensure
that the top surface of ply spar W7 seats flush with the top surface of the fuselage sides and
W6.
59.
Now, fit the wing center section sheeting W8 to the tabs on the
rear
of the fuselage sides/
ribs W6. Note: W8 will not actually cover ribs W6 as the upper surface of W6 needs to be
exposed to provide a landing point for the wing panels in step 61. The
rear
of W8 will butt
up flush against the fuselage top sheeting. Bond W8 to the fuselage top sheeting and the
rear
portion of the fuselage sides/ribs W6.
60.
Continue to bend/wrap W8 over the
forward
portion of the fuselage sides
adjacent
to ribs
W6 and bond with medium CA glue.
61.
Fit the
right
wing panel by inserting the tab on the end of spar W6 into the slot within rib W3.
Rest the
underside
of the wing panel on the
upper
surface of rib W6. With the wing panel
properly positioned begin to tack glue the wing to rib W6 and spar W7 with medium CA at
tab and notch locations. Repeat this step to install the
left
wing panel.
Windscreen
62.
Install the acetate windscreen at this time. Remove the protective backing from the wind
screen and wrap windscreen around fuselage positioning it evenly over the window
openings at
right
and
left
of fuselage. Retain the windscreen in position using small strips
of low-tack masking tape. Bond the windscreen to the assembly at several points along it’s
perimeter by lifting the acetate and placing a tiny drop of medium CA glue between the
windscreen and the fuselage side.
Tip: Do not place these drops close to your masking
tape as the glue may wick along the tape making an unsightly mess. Leave the tape mask
in place for 10-15 minutes or until the glue has cured.
