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 general
in nature and 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 .080” 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 .080” 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. Depending upon your engine selection you may need to enlarge the
holes.

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
Scale this page 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. Cut out NACA vent holes
3D-printed NACA vents are provided for the ventral fuselage. Measure, mark,
and cut holes in the fuselage halves to allow them to be mounted as shown. Units
shown in the diagram are in inches.

I.A.7. 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:
CORRECTION--The main landing gear door panel lines as molded on the wings of
Early production kits (kits produced prior to August 2022) are incorrect. Correct
cutting lines are shown in red on the diagram below. Check to see which version of the
kit you have. If you have an early version, you can use the 3D printed main wheel wells
to help mark where to cut the holes.

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.
I.B.2. Sand support column attach points

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 1.4 26 Aug 2022

The strongest joint is a chemically welded styrene to styrene joint–one that
is glued with solvent glue. For extremely strong construction use scrap
styrene to ‘wrap’ your wheel wells. This can be done before installing
them, or after and can be done for both the main wheel wells and the nose
wheel well. The goal is to make a styrene box to contain the resin part
and take stress off of the resin-styrene joint.

II.B.2. Install APU exhaust
The APU exhaust should be installed prior to cementing the fuselage halves
together. You will need to thin the vacformed part using sandpaper or a rotary
tool with grinding bit in order to accept the resin APU.
