BEFORE YOU BUILD
WARNING!!
This kit is not a toy.
This model is intended for the competent builder and RC pilot aged 14
years and older. It is the responsibility of the modeler to ensure the
model is airworthy before attempting to fly it.
Always ensure that any glue, paint or solvents used to build this kit are compatible with the
materials contained in this kit. Some glues and paint can melt Styrofoam and plastic that is
contained in this kit.
Before gluing any parts together, we strongly suggest trial fitting the parts without glue first;
to ensure that all the parts align and fit properly. This will ensure the airplane is built straight
and square.
ABOUT THE TOUGHJETS T-14 EDF
The ToughJets T-14 EDF was designed by life-long RC modeler Wayne Roberts to be the
highest performing fun scale RC propjet on the market. You’ll find the T-14 has an enormous
flight envelope. It’s capable of 65+mph, it’s highly aerobatic, yet it lands at near zero ground
speed in the slightest of headwinds.

LET’S BEGIN BUILDING
It is strongly suggested you review the drawings, photos and captions to familiarize yourself
with the design and construction of the model.
Before beginning construction, you will want to decide whether to paint or cover the foam
parts with heat shrink film such as EconoKote, or packaging tape. You may also choose to
leave these parts uncovered. If you choose EconoKote, or packaging tape, spray the surfaces
to be covered with 3M Type 77 spray adhesive prior to covering. Allow the adhesive to set for
5 minutes prior to applying the covering, this will improve the overall adhesion of the covering
to the foam. When covering the nacelles, do not apply covering material or paint to the
surfaces to be epoxied to the wing.
It is highly recommended to apply the covering material or paintprior to assembling the
model. Do NOT apply covering to the top edge and slant of the nacelle (see insert)

WING / NACELLE / FUSELAGE ASSEMBLY
Lay wing on a flat surface, bottom side up.
This is the side with the hinge slots and
crease.
Clean the bottom of the wing with rubbing
alcohol before gluing
Apply 5 minute epoxy to top of nacelle on
flat section only. Do not apply epoxy
to slanted section at this time. Do not let
epoxy clog vertical stab dowel holes see
insert photo
Carefully align nacelle with leading edge and
crease on the bottom of the wing.

©2011 ToughJets, LLC Kittery, ME Page 7 of 22
Ensure the nacelle is parallel and 90 degrees
to flutes in wing. You have some time to
make slight adjustments before epoxy cures
but move quickly.
Be sure that the nacelle is properly aligned
with crease
Hold the nacelle in place until the five-
minute epoxy cures, check that nacelle is
aligned with leading edge, crease and
centered on Vertical stabilizer dowel holes on
wing.
Repeat the steps to attach the second
nacelle to the wing. Nacelles should be
straight and parallel

©2011 ToughJets, LLC Kittery, ME Page 8 of 22
Now apply 5-minute epoxy to the slanted
sections on both nacelles.
Press both nacelles to leading edge of the
wing applying pressure on a smooth flat
surface for 5 minutes until the e
p
ox
y
cures
Turn the wing over, measure and mark on
the top the center of the wing
Apply 5 minute epoxy to both side of
fuselage wing slot. Slide the fuselage onto
the wing. Be sure that the fuselage is
centered straight and square to wing.

Epoxy 2 dowels into the flutes of each
vertical stabilizers. Position the dowels 1½”
and 4 ½” from the trailing edge. Leave
about 1 ½” of dowel exposed
Peirce foam with sharp dowel by pushing it
down into Vertical stabilizer dowel holes to
clear out foam to for dowels
Repeat steps for other side. It’s starting to
look like a plane now.
Insert stabilizer dowels it should be a
tight fit not needing glue, remaining
removable for transporting.

Apply a little 5 minute epoxy to the 3mm
carbon fiber shaft, then insert it in the
second wing flute from the hinge
(see photo)

INSTALLING MOTOR
Bolt motor to mount with 3mm x 14mm bolts
included.
Set your EDF unit in wing with ESC wires
facing down DO NOT omit intake ring
Line up motor straight and square. Mark
location and drill holes.

Bolt mount through wing and Coroplast®
stiffener don’t over tighten bolts. Place washer and nut on bolt do not over
tighten. (BOTTOM VIEW

CANOPY / BATTERY BOX ASSEMBLY
Carefully trim the canopy to fit the fusela
g
e. Cut the small piece of Coroplast® to fit the
rear part of the canopy.
Fit the Coroplast® to the canopy. Epoxy the Coroplast® piece and CA glue
canopy hinge into place to the inside of the
canopy, after painting the outside of the
canopy.

Cut a slit ½ “ in front of the battery box for
the canopy hinge.
T
est fit the hin
g
e. Then
g
lue into place.
The hinged canopy will cover the battery
box.
Drill a small hole and glue magnet to the
Coroplast at the rear of the canopy.

RADIO SYSTEM INSTALLATION
It may be necessary to trim the servo-
mounting hole to accommodate the servos.
Install the outboard servo into the
mounting
hole and glue in place, stacked on top of
inboard servo. We recommend
9 gram sub micro or similar type servo.
T
he canopy is now complete.
Drill a hole the same size as the magnet near
the battery box, position it such that it will
align with the magnet on the canopy. Ensure
the polarity of the magnet is such that they
are attracted when the canopy is closed.
Epoxy the magnet in place

Attach the control horn to the right elevon,
don’t over tighten.
Measure and cut the push rod to fit between
the servo arm and control horn.
Connect the push rod to the servo arm 2nd
hole from end and control horn middle hole.
Repeat steps for left side.
NOTE: WHEN SERVO IS IN NEUTRAL
POSITION, THERE SHOULD BE APPROX.
5/8” OF UP DEFLECTON ON THE
OUTBOARD FLIGHT CONTROLS TO
MAINTAIN LEVEL FLIGHT.
Bend the cut end to accommodate the push
rod keeper.

Two more servos are placed on the inboard
side of the nacelles opposite and above
outboard servos as seen on page 15 and 16.
The servos are connected with Y cords to
outboard elevon servos.

Cut slot in right nacelle for servo wire and
extension, single knife cut is sufficient here.
Embed servo wire and extension. Repeat
steps for left side.
Cut slot for electronic speed control wires, it
may be necessary to extend you electronic
speed control battery wires in order to reach
battery connector exit. Single knife cut is
sufficient here, then use flat tip screw driver
to open slot.
Servo wire exits on inside of nacelle.

Embed electronic speed control battery wires
in slot. Use double sided tape to hold speed
control and receiver in place.
you can mount your receiver under
or next to your electronic speed
control as shown in photo
Use servo Y leads to route wires as shown in photo. Once wires
are neatly placed they can be taped in place in the slots and to bottom of
wing with clear packaging tape or vinyl tape to match the color of the
wing. Care must be taken that the wires and receiver antenna are do
become entangle or severed by the fan.

Now you have a complete airplane that can be customized with decals tape or
paint to your liking. You may want to cover the exposed flute holes in the leading
edge of the wing and tail surfaces with tape. This does not affect the plane’s
performance.
NOTE: WHEN ELEVATOR STICK IS IN THE NEUTRAL POSITION THERE
SHOULD BE APPROX. 5/8” OF UP DEFLECTON (OR REFLEX) ON BOTH
OUTBOARD FLIGHT CONTROL SURFACES BOTH INBOARD SURFACES
SHOULD BE 3/16" UP TO MAINTAIN LEVEL FLIGHT.
