Fuselage
Fuselage parts are designated with an “F” followed by a numeric. Parts have been numbered so that the
fuselage assembly and required parts follows in numeric order from F1 to F25 (With F25 being used in
final assembly).
The fuselage is built upon a central crutch assembly, with sheet sides,formers and turtle deck stringers.
Many of the formers will need to be installed in a
forward
and
top
orientation.
Unless otherwise
specified, formers should be installed with the etched part number facing the
front
of the
assembly and any
top
or
bottom
designations followed.
You will dry fit the majority of this fuselage assembly together only gluing at the final instructional steps.
When parts cannot easily be retained with friction, use a single tiny drop of medium CA glue applied
sparingly through a CA glue applicator tip to “tack glue” the part in place. Should you commit an error in
assembly it will be easier to recover from the mistake and remove or correct the part fit in error if you do
not slather the assembly in glue after each step! Further, this method of assembly will allow our
interlocking design to do it’s job as each successive part installed within the fuselage will help pull the
entire structure square and true.
Receiver Tray
1.
Fit two ply parts RT to the nylon receiver clip to form the Receiver Tray.
Fuselage Central Crutch
2.
Fit the Receiver Tray assembly to the
bottom
of F1, and bond with medium CA at the tab
and notch locations.
3.
Fit former F2 to the
front
of F1. Ensure that F1 and the receiver tray are oriented
bottom
down
, and that F2 is oriented
top up
.
4.
Fit Former F3 to the
aft
end of F1, ensuring that it is oriented
top up
in relation to F1 and F2.
5.
Fit but do not glue ply motor mount F4 to the
front
of F2. Ensure that it is oriented t
op up
-
this is important to assure the correct offset of the motor to the
right
for controlled flight. F4
will fit somewhat loosely, and will angle down slightly. If necessary, F4 may be lightly tack
glued to F2 to hold it in position until the fuselage side is fit.
Right Fuselage Side
6.
Assemble the
right
fuselage side F5 by fitting and bonding F5b to the
aft
end of F5a. Orient
the parts so that the etched part numbers are facing
up
and are
right
side up.
Note: F5b
now features a balsa wood slug that fills the slot for the Horizontal Stabilizer, leave this slug
in place throughout the fuselage assembly process (regardless of the photo) as it will
greatly aide in your success in assembling the fuselage without breaking bits off of F5b.
7.
Fit the completed fuselage side F5 to the
right
side of the central crutch assembly, engaging
the tabs on F1 through F4, and the RT receiver tray, to the slots and notches in F5. Note
that the middle and lower tabs on F2 fit in oversize slots in the fuselage side. These tabs
should fit in the
forward
portion of the slot, leaving room for parts F6 and F7 to be fitted in
the next steps.
Landing Gear Pocket
8.
Fit the landing gear brace F6 to the over sized slots in F5, immediately behind F2.
Do not
bond.
