Assembly Guide

Thank you for purchasing a Titan Model Kit. These kits are intended for experienced intermediate to
advanced adult scale modelers. Kits will require you to measure, mark, cut, scratch-build, and modify
various pieces. Builders are cautioned to review the assembly instructions in their entirety prior to
beginning any work. These instructions are provided only as a guide. You may choose to alter the
sequence of steps, change techniques, or omit steps at your discretion. You will find the following
tools useful in your build: hobby knife, dial calipers, ruler or measuring tape, drill with various bit sizes,
rotary tool (Dremel or equivalent), sand paper of various grit, sanding block, styrene model cement
(solvent based), and cyanoacrylate glue (Superglue or equivalent).
Assembly instructions may contain images that do not correspond precisely to the physical kit parts.
Physical parts are in a state of continuous improvement and you may have earlier or later versions of
an individual part or kit than what is shown in the assembly instructions. The images are intended to
provide you with general orientation only. Additionally some images are used to illustrate concepts
which are common to multiple kits.
Screenshots of CAD models are used for concept illustration only and the images may contain
elements that may or may not be present in the physical parts. For instance, cabin window and door
outlines are shown in these images to help in visual orientation and are not present in the physical
parts. Screenshots may omit adjacent parts for clarity.

I. PARTS PREPARATION
I.A VACFORM PARTS
I.A.1. Remove parts from sheet:
Carefully remove the parts by cutting along the silhouette of the part with a sharp utility knife.
You may find it helpful to mark the cut lines with pencil prior to cutting. Always cut from the
top of the parts, never from the bottom. Multiple shallow passes will always yield a better
result than trying to cut through on a single pass.

I.A.2. Remove stock thickness:
Once parts are cut away from their sheet they will still need to have the sheet thickness
removed from them. As can be seen from the below photo, the .090” sheet thickness
between the red lines should be removed. Coarse sandpaper in a sanding block is
recommended to remove this material. Work slowly, checking progress often.

I.A.3. Thin trailing edges:
As delivered, the trailing edges of the wings and tail parts are the thickness of the plastic
sheet used to produce them. If left alone, assembling raw parts will result in a trailing edge
that is too thick for scale. Using 220 grit sandpaper, thin all trailing edges from the .090”
material thickness to approximately .010”. Work slowly, checking thickness and consistency
as you go. This will result in trailing edges that are more “to-scale”

I.A.4. Drill out engine and flap track attachments:
Engine and flap track fairing attachment points should be drilled out with a ⅛” (3mm)
brad-point drill bit. Hole diameter may then need to be enlarged to accommodate certain
engines.

I.A.5. Cut out wing & tail passthroughs
Remove plastic to allow for the wing and tail assemblies to pass through the fuselage halves
as shown. The attached templates can be scaled and used to help you know exactly where
to cut.

Wing Passthrough Template
If you desire more guidance on the plastic to be removed to accommodate the wing
and tail passthroughs, the below templates can be scaled with a copy machine to ensure that
the block below is exactly 1 inch wide. Use as template to remove material for wing
passthrough.

Tailplane Passthrough Template
Scale this page with a copy machine to ensure that the block below is exactly 1 inch
wide. Use as a template to remove material for tailplane passthrough.

I.A.6. Install 90° angle styrene reinforcement strips
¼” styrene angle strips are provided to add rigidity to the fuselage and to increase the
area of the fuselage joint for glue-up. Install as shown below. Install on BOTH fuselage
halves. You may wish to add additional bracing or joint reinforcement using scrap styrene at
your discretion.

I.A.7. OPTION: Landing Gear Cutouts:
Typically, only the aft nose gear doors are open during normal operations. Use the
panel lines on the model or use the measurement guide below to remove the desired
material.

Additional material will need to be removed from the lower wing halves to accommodate
installation of the main landing gear bays.

I.B RESIN PARTS PREPARATION
I.B.1. Remove support columns:
Some 3D-printed parts (wheels especially) may come with printer supports still attached.
Carefully remove supports with a utility knife or sprue cutter and gently sand attachment point
dimples away.

II. ASSEMBLY
II.A. GENERAL
Vacform parts are made from high impact polystyrene (HIPS) plastic. Vacform parts should
be glued to one another using solvent based ‘glue’. 3D printed parts should be glued to one
another and to vacformed parts using cyanoacrylate (Superglue or equivalent) or 2-part
epoxy.
II.B.1. OPTION: Install wheel wells:
Wheel wells should be installed prior to assembling fuselage halves and wings.
© Titan Model Kits 18 Revision 1.2 26 Aug 2022

© Titan Model Kits 19 Revision 1.2 26 Aug 2022

Main gear wells must be installed in the fuselage halves first. Wings will have to be fitted after
the fuselage halves are glued together. Take your time dry-fitting everything in order to
ensure that glued assembly goes smoothly.
