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 TOUGH JETS T-15 EDF
The Tough Jets T-15 EDF was designed by life-long RC modeler Wayne Roberts to be the
highest performing fun scale Electric Ducted Fan on the market. You’ll find the T-15 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 or painting the nacelles, do not apply covering material to the
surfaces to be epoxied to the wing.
It is recommended to apply the covering material or paint prior 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.
Carefully align nacelle with leading edge and
crease on the bottom of the wing.

©2013 ToughJets, LLC Kittery, ME Page 7 of 22
Ensure the nacelle is parallel and 90 degrees
to prop slot 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

©2013 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
Twist a 1/8-inch drill bit in Vertical stabilizer
dowel holes to clear out foam to for dowels
Place Vertical stabilizer in wing at this time
you can chose to glue in place permanently
or leave loose so you can remove
for transporting model.
Repeat steps for other side. It’s starting to
look like a plane now.

Apply a little 5 minute epoxy to the 30 inch
carbon fiber shaft, then insert it in a wing
flute approximately 2, 7/8th inches behind
the EDF (see photo)
Apply a little 5 minute epoxy to the
25 inch carbon fiber shaft then insert it
in a wing flite approximately 8, 7/8th
inches behind the EDF (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.

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 glue
canopy hinge into place to the inside of the
canopy, after painting the outside of the
canopy.

Cut a slit 1/4 “ 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
Bend the cut end to accommodate the push
rod keeper.
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
Measure and cut the push rod to fit
between the servo arm and control horn.

©2013 ToughJets, LLC Kittery, ME Page 16 of 22
Attach the control horn to the right elevon,
don’t over tighten.
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.
1/2” OF UP DEFLECTON ON THE
FLIGHT CONTROLS TO MAINTAIN
LEVEL FLIGHT.
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.
It may be necessary to trim the servo-
mounting hole to accommodate the servos.

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

Servo wire exits on inside of nacelle. 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.

Embed electronic speed control battery wires
in slot. Use double sided tape to hold speed
control in place.
Mount your receiver in slot cut in fueslage
under the electronic speed control
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 do not
become entangle or severed by the fan blades

Now you have a complete airplane that can be customized with decals tape or
paint to your liking.
NOTE: WHEN ELEVATOR STICK IS IN THE NEUTRAL POSITION THERE
SHOULD BE APPROX. 1/2” OF UP DEFLECTON (OR REFLEX) ON BOTH
OUTBOARD FLIGHT CONTROL SURFACES TO MAINTAIN LEVEL FLIGHT.
