Before Starting Assembly
Before beginning the assembly of your Twist, remove each part from its bag for inspection. Closely inspect the fuselage, wing
panels, rudder, and stabilizer for damage. If you find any damaged or missing parts, contact the place of purchase.
If you find any wrinkles in the covering, use a heat gun or covering iron to remove them. Use caution while working around areas
where the colors overlap to prevent separating the colors.

Using the Manual
This manual is divided into sections to help make assembly easier to understand and to provide breaks between each major
section. In addition, check boxes have been placed next to each step to keep track of each step completed. Steps with two boxes
indicate the step will require repeating, such as for a right or left wing panel, two servos, etc. Remember to take your time and
follow the directions.

Section 1: Attaching the Wing to the Fuselage Section 2: Horizontal Stabilizer Installation
Required Parts
Wing • Fuselage•
1/4 x 1 3/4-inch wing dowel•
1/4-20 x 2-inch nylon bolt•
Required Tools and Adhesives
6-minute epoxy • Sandpaper•
Flat blade screwdriver•
Step 1
Locate the 1/4 x 1 3/4-inch wing dowel. Sand a small
taper on one end of the dowel to make it easier to attach the
wing to the fuselage.
Step 2
Glue the dowel into the wing using 6-minute epoxy. Make sure
there is about 1/2-inch of the dowel exposed.
Step 3
Place the wing onto the fuselage. Secure the wing using the
1/4-20 x 2-inch nylon bolt.
Required Parts
Wing • Fuselage•
Horizontal stabilizer • Elevator joiner wire•
Required Tools and Adhesives
Flat blade screwdriver • Sandpaper•
Felt-tipped pen • Paper towel•
Rubbing alcohol•
Step 1
Slide the stab into the slot in the fuselage, with the leading
edge pushed forward in the slot. Center the stab in the opening
by measuring the distance from the fuselage to each tip. The
stab is aligned when both measurements are identical.
A
A'
A=A'
Step 2
Check the distance from each stab tip to each wing tip. These
measurements must also be equal.
B B'
B=B'
Step 3
The last alignment step is making sure the wing and stabilizer
are parallel. If they are not, lightly sand the opening in the
fuselage for the stab until the stab rests parallel to the wing.
Equal Distances
Step 4
Use a felt-tipped pen to trace the outline of the fuselage on the
top and bottom of the stab.

Section 2: Horizontal Stabilizer Installation (continued) Section 3: Vertical Stabilizer Installation
Step 5
Remove the stab and use a hobby knife with a brand new blade
to remove the covering 1/16-inch inside the lines just drawn.
Note: DO NOT cut into the underlying wood. Let the
knife “float” across the covering. Cutting into the wood will
weaken the stabilizer and may cause it to fail in flight.
Hint: You can use a soldering iron instead of a hobby knife
to remove the covering. Doing so will eliminate accidentally
cutting into the stabilizer.
Step 6
Place the elevator joiner wire into the slot for the stab.
Reposition the stab into the fuselage. It may be necessary
to trim the opening at the rear to allow for clearance for the
joiner wire.
Hint: Use a little rubbing alcohol and a paper towel to remove
the felt-tipped marker lines once they are no longer needed.
Step 7
Slide the stabilizer from the fuselage far enough to expose the
uncovered area. Mix 1/2 ounce of 30-minute epoxy. Apply the
epoxy to the exposed area on both the top and bottom of the
stab. Slide the stab back into position and double-check the
alignment of the stab. Remove any excess epoxy using a paper
towel and rubbing alcohol.
Hint: Use a little masking tape to keep the joiner wire out of
the way until it’s time to install the elevators. Also make sure
there is no epoxy on the joiner wire.
Required Parts
Wing • Fuselage•
Vertical stabilizer•
Required Tools and Adhesives
30-minute epoxy • Sandpaper•
Square • Ruler•
Felt-tipped pen•
Step 1
Locate the vertical stabilizer (fin) and slide it into position.
Position the fin so it is fully forward in the slot in the fuselage.
Step 2
Check the alignment between the fin and stab. The fin must be
90-degrees to the stab to be in alignment. Sand the opening in
the fuselage if necessary to get the perfect alignment.
Step 3
Trace the outline of the fuselage onto the fin.
Step 4
Remove the covering 1/16-inch below the line drawn
in the last step.
Step 5
Mix 1/2 ounce of 30-minute epoxy. Apply the epoxy to the tab
on the fin and to the area on the top of the fuselage where the
covering was removed. Position the fin in the slot and check
the alignment. Use masking tape to hold the fin in position until
the epoxy fully cures.
Hint: Use rubbing alcohol and a paper towel to clean up any
excess epoxy.

Section 4: Ailerons Installation Section 4: Ailerons Installation (continued)
Required Parts
Wing • CA hinge (8)•
Aileron (left and right)•
Required Tools and Adhesives
Thin CA • T-pins•
Step 1
Locate 8 of the CA hinges. Place a T-pin in the center of four of
the hinges.
Step 2
Place the hinges in the precut slots in the aileron (or wing
if you prefer). The T-pin will rest against the edge when
installed correctly.
Step 3
Slide the aileron and wing together. The gap between
the aileron and wing should be infinitely small,
approximately 1/64-inch.
Hint: Be careful of the T-pins, as they can be sharp.
Step 4
Use a ruler to align the end of the aileron to the wing.
Note: Do not use CA accelerator during the hinging process.
The CA must be allowed to soak into the hinge to provide the
best bond. Using accelerator will not provide enough time for
this process.
Step 5
Remove the T-pins and apply thin CA to each hinge. Make sure
the hinge is fully saturated with CA. Use a paper towel and CA
remover/debonder to clean up any excess CA from the wing
and/or aileron.
Step 6
Firmly grasp the wing and aileron and gently pull
on the aileron to ensure the hinges are secure and cannot be
pulled apart. Use caution when gripping the wing and aileron to
avoid crushing the structure.
Step 7
Work the aileron up and down several times to work in the
hinges and check for proper movement.
Step 8
Repeat Steps 1 through 7 for the remaining aileron.

Elevator (left and right) • CA hinge (6)•
Required Tools and Adhesives
Thin CA • T-pins•
30-minute epoxy • Sandpaper•
Drill • Drill bit: 9/64-inch•
Ruler•
Step 1
Locate three CA hinges. Place a T-pin in the center of the
hinges. Place the hinges into the elevator half.
Step 2
Test fit the elevator and stab together. The elevator joiner wire
will be inserted into the pre-drilled hole.
Step 3
Mix 1/2 ounce of 30-minute epoxy and apply it to the
groove and hole in the elevator half. Insert the elevator joiner
wire. Remove any excess epoxy using rubbing alcohol and a
paper towel.
Note: You can combine this step with the following step if you
like. This will hold the elevator in position while the epoxy
cures.
Step 4
Check to make sure the elevator moves freely. It should not rub
against the stabilizer at the tip. Check to make sure the hinge
gap between the elevator and stabilizer is roughly 1/64-inch.
Apply thin CA to both sides of the hinge. Make sure to saturate
the hinge and don’t use accelerator.
Step 5
Once the CA and epoxy have fully cured, gently pull on the
elevator and stab to make sure the hinges are well glued. Flex
the elevators a few times to break in the hinges.

Step 1
Locate the pre-drilled hole in the bottom of the rudder. This is
the hole for the vertical shaft of the tailwheel assembly.
Step 2
Temporarily mount the tailwheel assembly to the bottom of
the rudder. Do not glue at this time. Slide the nylon tailwheel
support brackets to be evenly spaced along the tailwheel wire.
Step 3
Mark where you drill the two locations for the
tailwheel support.
Step 4
Drill through the bottom of the rudder with the
5/64-inch (2mm) drill.
Step 5
Mix up a small batch of 6-minute epoxy. Using a toothpick
insert a small amount of the epoxy in the hole in the bottom of
the rudder. Insert the vertical tailwheel wire into the hole with
the epoxy and mount the nylon brackets to the rudder with the
hardware included.

as done for the ailerons and elevator.
Step 2
Install the hinges in the rudder.
Step 3
Test fit the rudder to the fuselage. Make sure the rudder will
rest tight against the fin and fuselage.
Step 4
Check to make sure the rudder moves freely. It should not rub
against the fin at the tip. Apply thin CA to both sides of the
hinge. Make sure to saturate the hinge, and don’t use
accelerator. Use a paper towel and CA debonder/remover to
clean up any excess CA.
Step 5
Once the CA and epoxy have fully cured, give the rudder and
