wing half. When satisfied with the fit, mix more epoxy, and attach
the other wing half to the fuselage - again making sure it’s 90° to
the fuselage and in-line with the other wing.
Step 85 - Final airframe assembly (stab attachment)
Locate the stab assembly
and test fit into the slot in the
rear of the fuselage. Sand the
slot as necessary to obtain a
good fit - make sure not to
sand the stab.
Once the stab can be properly
slid into the fuselage, look at
the fuselage straight on, from
the nose (or tail) and make sure that the stab is level with the wing.
If not, remove the stab and gently sand the stab slot a little at time.
Do this a little at a time, until you get the stab in line with the wings.
Step 86 - Final airframe assembly (stab attachment)
Now you also need to
check the side to side
alignment. Using this
diagram as a guide, take
measurements, from the
wing tips to the stab tips.
Slide the stab from side
to side as needed to
make sure that the stab is
equidistant as shown here.
When in the right spot, use
a pencil to make a line on
the stab where it meets the fuselage.
Remove the stab and mix just enough epoxy to glue the stab in
place. Make sure things stay aligned while the glue is curing.
Step 87 - Main gear (axle hole)
Locate the main gear halves from the
hardware bag. Each of these need a
5/16” hole drilled into the bottom
bend, as shown here. This will allow
the axle shaft to be inserted in the
next step.
Step 88 - Main gear (attach axle)
Locate the axle shafts and their matching
locknuts. These are now attached to the
landing gear halves as shown here. Make sure
the lock nuts are tightened firmly.
Step 89 - Main gear (mounting)
Locate the three 4-40 x 1-1/2”
bolts and three 4-40 lock nuts.
These are used to bolt the main
gear to the fuselage. Do this now,
paying attention to the angle of
the main gear. The rear of the
main gear should sweep slightly
forward.
Make sure the lock nuts are tightened firmly.
Step 89 - Wheelpants (outer wall brace)
Locate both wheelpants and two P5s from LP3.
One P5 is glued to the inside of the outer wall
of each wheelpant to double-up and strengthen
the axle hole. Note that you’ll need to make
sure the left wheelpant is a mirror image of the
right wheelpant.
Step 90 - Wheelpants (attaching)
Now it’s time to glue the wheelpants to the
inner wall brace. To do this correctly, it’s
best to prop-up the airframe by the wings
and the tail so it is level. This will give you
unobstructed access to the landing gear.
Locate one P4 from LP3. Slide it onto one
of the axles, making sure that the pre-cut hex shape fits firmly over
the axle’s machined hex face. This pre-cut shape helps to locate
the finished wheelpant and keep it from rotating.
Step 91 - Wheelpants (test fit)
Now, test fit the wheelpant
on to that same axle. The
axle should slide completely
through the wheelpant and
protrude about an 1/8” or so
on the outside. This photo
shows how it works, only up-
side-down.
Step 92 - Wheelpants (attaching)
Now it’s time to glue on the wheelpant to the inner wall brace.
Slide the wheelpant back off the axle and apply some glue to the
outside face of the P4, where it will touch the wheelpant.
Now, slide the wheelpant back on, paying attention to making it
level with the airframe. When you’re satisfied with the alignment,
push it up against F4 and allow the glue to cure.
Step 93 - Wheelpants (P6)
Locate two of the P6s from LP3. These
are glued to the outside surface of P4,
butting up against the axle to give a
more secure fit, but not glued to the
aluminum main gear.
When cured, the completed wheelpant
can now be slid off the axle. Now, go
back to step 90 and repeat these steps
to complete the other wheelpant.
