TOOL AND ADHESIVES NEEDED
Tools shown and listed are suggestions only.
Depending on your building technique you may not
need everything indicated – and/or – you may find that
other tools available to yourself may be of benefit to
your Build.
It is also recommended that you have a flat building
surface, one that will accept stick pins and push pins.
An Acrostic Ceiling panel from your local hardware
store fits this bill nicely, and will lay flat on your work
table. Over size / long push pins are available at your
local craft store. These two items are by no means
required, but will aid in the building process, and can
be used for future projects

the build
CONSTRUCTION METHODS:
Building surface should be at least 2ft x 4ft and at. Weights or some small heavy objects will be handy for holding things in place
during the time glue is setting.
Welders glue is used for FOAM TO FOAM joints. Thin and Medium CA can be used on the PLASTIC TO FOAM and CARBON TO FOAM
joints. When using the Welders glue for a butt joint, apply a thin lm to each surface, allow to sit for approx ve minutes and
then assemble. Note that this method will create a nearly instant bond, so locate carefully when bringing the two pieces together. If
alignment is necessary or a slip joint, do not allow the glue to tack up, simple apply and join immediately, you will have several
minutes to locate the two parts before the glue sets up. In most cases the parts being glued can be handled with care in 30 minutes,
full cure is approx 24 hours.
The above picture items will be needed to nish the model.
A power combo (Twisted Hobbys’ Combo pictured above),
and a battery. Note - the Welders and Receiver are NOT part
of the power combo, everything else shown is.
Start the build by locating the two wings, the elevator and
the rudder. Fold back as shown and weigh them down for
about an hour to loosen up the hinge area. Now is also a
great time to setup your radio and to test that all your
electronics are functioning properly.

Rev: 2015.11.30.v01a page 8
Welders, Foam-Tac or CA can be used
as the primary method of joining the
parts. This Build will use Welders for all
joints unless called out otherwise. Two
to three tubes of Welders are needed.
After the hinged parts have sat folded
back for an hour or so, assembly can
start. Locate the elevator, 5x1x250
spar, 3x1x250 spar and 2 of the
3x1x100 spars (or 1 of 3x1x200).
Start from the top side and with the
3x1x250 spar. With the tip of the
Welders’ nozzle, squeeze glue into the
pre-cut slot.
Flip the elevator over to the bottom side
and ll the long slit with glue like was
done on the top side.
Make sure the spar is fully seated and
ush as shown, wipe away any glue
that squished out.
Lay the carbon spar into the slot.

Rev: 2015.11.30.v01a page 9
Install the 5x1x250 spar into the slot.
Make sure it is ush and wipe away
any extra glue.
Next is the two pieces that install as
pictured above. Some kits have 2 pieces
3x1x100, some have 1 piece 3x1x200. If
your kit has the 200mm long piece, cut
it in half.
Fill both slits with Welders.
Note that there is a small round nub,
and a pre-cut slot. these should line
up. Test t to verify.
Wings are joined together next. Note
that the bottom of the fuselage (side
with the servo cut outs) and the bottom
of the wings should be facing UP.
Install the 2 spars, again making sure
they are ush and wipe away any extra
glue. Set aside for now with some
weights to hold it at while the glue
dries.

Rev: 2015.11.30.v01a page 10
Do this for both sides. Double check
that you are working with the
BOTTOMS of all three parts facing UP.
The “Tack Up” method will be used to
join the wings to the fuselage. Apply a
medium bead of welders to the wing.
Bring the two parts together to transfer
the glue, then separate immediately.
Make sure that during the “transfering”
of glue process that an even coat is on
both mating surfaces. Let set for about
5 minutes. Then join the pieces making
sure to apply pressure....
Make sure the slit is clear where the
wing and fuselage meet. Test t the
spar to make sure it sits ush to the
surface of the wing.
Main spars are next, there is one for
the top and one for the bottom, they are
both 5x1x1000.
.... to the work surface in the area of
the slit for the spar. This will ensure
that the leading and trailing edges will
locate at the center of the fuselage.
Repeat for the other wing.

Rev: 2015.11.30.v01a page 11
With the nozzle of the Welders’ tube,
squeeze some glue into the precut slot.
Install the spar, make sure that it is
fully seated and ush to a little below
the surface of the wing
Wipe away any extra glue. Note - just
pass over once with a paper towel,
wiping a second or third time will mess
up the printing on the foam.
Flip back over so that the under side is
facing up. Weigh down with some heavy
objects as shown and let this
thoroughly dry before handling again.
Wipe away any extra glue, again.... just
one pass to preserve the integrity of the
printed graphics
Flip the assmebly over and repeat for
the top side spar. Fill the slit with glue,
and install the 1000mm long spar.

Rev: 2015.11.30.v01a page 12
With under side of the fuselage and the
underside of the elevator facing up,
glue the two pieces together. The
elevator is “keyed” to help with correct
orientation.
Make sure the two pieces are fully
seated to each other. If so, squareness
should be really close, double check
with a tape measure by measuring from
elevator tips to the wing tips.
Once the previous step has dried,
prepare to install the fuselage
stiffeners. Locate the two pieces of
3x1x550 carbon spars.
Let this dry a little while before
handling. Weigh everything down to
ensure that the assembly dries in a nice
and at condition.
Install the spar and wipe away any
extra glue. Repeat for the second spar.
Squeeze some Welders into the
designated slot.

Rev: 2015.11.30.v01a page 13
While the previous step is drying, locate
the ber glass parts tree.
Break out the 3 landing gear base parts
as pictured above. Roughen up the legs
of the two side pieces and one complete
side of the center piece.
Take a close look at the the next three
pictures to get the right orientation of
the parts. Hold with your nger tips
and apply a little thin CA and hit with
Kicker
Finished assembly, note the glue joint
does not have to be super robust, but
good enough to hold things together
during assembly into the fuselage.
Make sure it is all realitevly square.
Once one of the side pieces is attached,
repeat for the other side. Note
orientation is critical, make sure you
have matched these pictures.
Under side of the assembly. Note that it
is the near side of the center piece that
is roughed up.

Rev: 2015.11.30.v01a page 14
Firewall and associated carbon stiffener
spars are next. Locate the motor mount
and four 2.5x1.5x200 carbon
rectangles. Note the metal mount to the
left is an Optional Upgrade part.
This build will be done with the
Optional Upgrade Motor Mount
pictured above, the stock wood one will
install in the exact same manner.
- TEST FIT -
This and the next three pictures show
test tting of the motor mount, the
carbon rectangle stiffeners and the
landing gear platform.
- TEST FIT -
Flip the fuselage over and test t the
nal two carbon rectangle. They too
should capture the notches in the
motor mount.
- TEST FIT -
Insert the LG platform into it’s
respective holes. Note that you will have
to remove a little foam near the carbon
rectangle in order for it to set ush.
- TEST FIT -
Install the motor mount, align the
notches with the foam slits and install
the carbon spar so they capture the
notches in the mount as shown.

Rev: 2015.11.30.v01a page 15
Once you are happy with the tment
and understand how all the part are
installed, remove them all and prepare
to re-assembly with glue
Start by attaching the motor mount.
Put some glue into both the left and
right slots as shown.
Apply some Welders to the horizontal
tabs, front and back as shown.
Flip the airframe over now so the
BOTTOM SIDE is facing up. Squeeze
some Welders into both to the slits.
Install the TOP SIDE rectangles by
squeezing glue into the slit and
pressing them in, make sure they
engage the motor mount and wipe away
any excess glue.
Slide the mount into position, working
it a little from side to side to get good
glue distribution. Make sure the slots
and motor mount notch line up.

Rev: 2015.11.30.v01a page 16
Install the rectangles like was done on
the top, and again making sure that
they engage the notches in the motor
mount
Apply a medium coat of Welders to the
under side of the LG Platform.
Squeeze some glue into each of the four
holes where the tabs will insert.
Once the previous step has dried, it is
time to attach the lower horizontal
fuselage piece. Test t, then apply glue.
Note - avoid glue in the areas noted in
the next two pictures.
Apply some weights to the whole thing
and let it set like this until the glue has
dried. Note a piece of tape is being used
to keep the front tabs of the nose in
contact with the motor mount.
Slide the LG Platform into position.
Applying enough pressure to ensure
that the glue is evenly dispersed. Wipe
away any extra glue.

Rev: 2015.11.30.v01a page 17
Avoid glue in the area where the carbon
landing gear struts will pass.
Avoid glue in the area where the
elevator and rudder servos install.
With the main part of the assembly nice
and at on your work surface, press the
lower horizontal into all it’s tabbed
areas, don’t forget to put glue on the
motor mount tab and slot as well.
While the previous step is drying,
attach the canopy to the upper vertical
fuselage section. Tack up Method can
be used for this step.
Once happy with the squareness and t
of the glue joint... weight everything
down to ensure it will dry nice and at.
Once it is all pressed together, wipe
away any extra glue and check for
squareness along the length of the
fuselage. With the thickness of the foam
it should be pretty square on it’s own.

Rev: 2015.11.30.v01a page 18
Once the glue has tacked up, bring the
two piece togehter.
Locate all the items pictured above.
Deburr the break out tabs and roughen
up the bases of the horns and tail skid.
Enlarge the second in servo horn hole
to .060” diameter and match drill a
.080” dia hole in the berglass servo
extension arm. Repeat this for all four
arms. Get 4 screws from the servo bags.
Make sure you servo is electronically
centered, and attach the horns as need
for each servo. Right aileron servo is
shown above, and will be the subject of
the next couple pictures / steps.
Other side of the nished horns.
Put a little dab of Welders on the under
side of the stock arms and then fasten
the extensions with the screws aquired
from the servo bags. Snip off the extra
length with some ush cutters

Rev: 2015.11.30.v01a page 19
All the servo cut outs need to have slits
added for the servo tangs. Position the
servo directly over the hole and make a
slit in the foam where the tang needs to
insert. Do this for both tangs.
Press the servo in, making sure it goes
all the way ush. It may be necessary
to make a little relief in the foam for the
servo cable. No Glue yet. It will need to
be remove in a couple steps.
Locate the two shortest 1.8mm dia
carbon rods (they may be a little
longer), 2 brass ferrules and 4 ball
links. Thin CA will be used for
assembly.
From the CENTER of the hole of the
bass ball in the ball link, measure off
73mm and cut the rod. Use a rolling
action with a hobby knife to score the
rod, then snap apart at that position.
Thread the ball link onto the ferrule
until there is approx 6.5mm between
the shoulder of the ferrule and the open
end of the ball link.
Slide a ferrule onto one end of the
carbon rod make sure it is fully
engaged, then apply a drop of CA to the
open end and let it wick in. Set with
Kicker

Rev: 2015.11.30.v01a page 20
Install on of the other ball links onto
the free end of the rod. The rod may
need to be sanded a little. 78mm from
hole to hole is the goal. Attach with CA
and Kick.
Attach the control rod to the servo and
aileron control horn as shown above.
Use a little thread locker on the
threads. Make sure and install from the
sides shown above.
Press the servo back into is pocket, and
with a straight edge, align the base of
the control horn with the angle of the
servo.
Once you are happy with everything,
install the servo with a medium dab of
low temp hot glue at the bottom of the
pocket, and the horn with Welders into
the slit that was cut.
With everything in position, the
assembly should look like the picture
above. Note that the servo horn is 90
degrees to the servo and not the rod.
Make a slit for the horn. It should be
deep enough so the corn at the back of
the horn is ush with the foam and the
front of the horn matches the prole of
the hinged area.
