Fuselage
Fuselage parts are designated with the letter “F” followed by a number. Parts have been numbered so
that the fuselage assembly follows a sequential order: F1 to F37.
Note:
When initially bonding parts, use a single, small drop of medium CA glue, applied sparingly with 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 in error, if you do not soak the assembly
with glue after each step! This method of assembly will allow our interlocking design to do its job.
As each successive part is installed within the fuselage, it will help pull the entire structure square and
true. When a major assembly is completed, revisit all joints and bond completely. Do not use excessive
amounts of glue, as this only adds weight to the model.
1.
Motor Mount –
Lay part F1 (sheet 10/10, 1/32 in. ply) on the work surface with the side
etched “Top” facing
up
. Fit and bond two F2s (sheet 10/10, 1/32 in. ply) to the
inner
set of
slots in F1.
2.
Turn the assembly
upside down
on the work surface. Fit and bond two F3s (sheet 10/10,
1/32 in. ply) to the
outer
slots in F1.
3.
Turn the motor mount assembly
right side up
. Slide part F4 (hardware bag, 1/16 in. ply)
onto the long tabs at the
front
of parts F2 and F3. Ensure that part F4 is firmly seated
against parts F1, F2, and F3.
4.
Fit and “tack glue” former F5 (sheet 05/10, 1/20 in. balsa) to the
rear
of F1. Orient F5 so
that the tab on part F5 is at the
top
of the assembly.
5.
Receiver Tray/Central Fuselage Crutch –
Fit parts F6a and F6b (sheet 10/10, 1/32 in. ply)
to the notches in the Delrin receiver clip (hardware bag).
Ensure that F6a is next to the
long arm of the receiver clip.
6.
Lay the central fuselage crutch (part F7) on the work surface, with the side etched “Bottom”
facing
up
. Fit the receiver tray to F7. Orient the receiver clip so that the long arm of the clip
is toward the
front
of part F7. Bond with CA.
7.
Turn F7
right side up
, so that the receiver tray is
underneath
. Fit and “tack glue” F7 to the
back of F5.
8.
Assemble former F8 from parts F8a, F8c, and two parts F8b, (sheet 10/10, 1/32 in. ply).
Bond with CA.
