Designed as a trainer and light combat aircraft for use
by the British Royal Air Force, the British Aerospace
(BAe) Hawk was mainly used to teach air combat,
air-to-air firing, air-to-ground firing, low-altitude
flying techniques and operation procedures. There are
currently over 900 Hawks in operation and nearly 2
million flying hours have been logged on the Hawk.
E-flite’s BAe Hawk 15 DF ARF is a sport scale version
of the British trainer. Constructed of fiberglass and
balsa, the fuselage is prefinished with scale details. The
Hawk boasts the rare and very visible Central Flying
School airshow trim scheme from 1987 in red, white
and blue.
This performance model was designed around E-flite’s
Delta V 15 (69mm) fan unit and matched 15 DF
brushless motor. Pilots can use a 3-cell battery pack
or utilize a 4-cell battery pack for increased vertical
performance. The built-in fan mounts make installing
the fan easy—just drop in the fan unit and tighten four
screws. The removable front hatch also allows easy
access to the radio equipment and battery. The entire
trim scheme is prepainted, pre-trimmed, the wings are
covered in UltraCote® and all the decals have already
been applied.

Lithium Polymer batteries are significantly
more volatile than alkaline or Ni-Cd/
Ni-MH batteries used in RC applications.
All manufacturer’s instructions and warnings
must be followed closely. Mishandling of
Li-Po batteries can result in fire. Always
follow the manufacturer’s instructions when
disposing of Lithium Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause
serious bodily harm and damage to property. Fly
only in open areas, preferably at AMA (Academy of
Model Aeronautics) approved flying sites, following all
instructions included with your radio.
Keep loose items that can get entangled in the
propeller away from the prop, including loose clothing,
or other objects such as pencils and screwdrivers.
Especially keep your hands away from the propeller.
During the course of building your BAe Hawk we
suggest that you use a soft base for the building
surface. Such things as a foam stand, large piece of
bedding foam or a thick bath towel will work well and
help protect the model from damage during assembly.

Fan Installation
Trim for motor wires
Required Parts
Fuselage Fan assembly
Thrust tube
2mm x 8mm sheet metal screw (4)
Required Tools and Adhesives
Felt-tip pen Hobby scissors
Drill Drill bit: 1/16-inch (1.5mm)
Thin CA Phillips screwdriver: #1
1. Remove the cover from the fuselage to allow
access for the fan assembly installation. Set the
cover aside in a safe place.
3. Position the thrust tube on the fan assembly
so it is rotated as shown. This will leave the gap
necessary to fit the tube onto the fan assembly,
allowing for clearance between the thrust tube and
the fan mount to the fuselage.
4. Use a felt-tip pen to mark the position of the
motor wires onto the thrust tube.
5. Use hobby scissors to trim the thrust tube for the
motor wires. Set the thrust tube aside at this time as
it will not be installed until later in the manual.
6. Move the elevator pushrod tube upwards to
allow for the installation of the fan assembly.
2. Slide the thrust tube onto the fan assembly and
over the motor wires.
7. Guide the motor wires into the hole in the
fuselage former. The wires will be on the side of the
center line former that is away from the opening as
shown.
4 E-flite BAe Hawk ARF Assembly Manual
8. Install the fan by inserting it tail-end first into the
fuselage as shown. The technique is very similar to
parallel parking by backing the assembly in then
moving it forward inside the fuselage.
9. Slide the fan assembly as far forward in the
fuselage as possible without damaging the fan
assembly or fuselage. The front edge of the fan
assembly will fit snugly into the fan intake inside
the fuselage.
10. Use a drill and 1/16-inch (1.5mm) drill bit
to drill four 1/16-inch (1.5mm) holes into the
fan mount in the fuselage that correspond to
the notches in the mounting flanges of the fan
assembly. Position the holes as close to the center
of the assembly to prevent the fan from shifting in
the fuselage.
11. Apply 2–3 drops of thin CA into each of the
four holes to harden the surrounding wood. This
is done to provide a harder surface for the screws
to bite into and will help in preventing them from
vibrating loose.
5E-flite BAe Hawk ARF Assembly Manual
12. Use a #1 Phillips screwdriver and four 2mm x
8mm sheet metal screws to secure the fan assembly
inside the fuselage.
Aileron Servo Installation
Required Parts
Left wing panel Right wing panel
2.5 x 10mm sheet metal screw (4)
Aileron servo mount (2)
Servo mounting strap (2)
Required Tools and Adhesives
Servo (2) Medium grit sandpaper
6-minute epoxy Phillips screwdriver: #1
1. Relocate the string from the aileron opening so it
is near one of the corners. This will give full access
to the opening and prevent accidentally gluing the
string into the wing.
2. Measure and mark the opening for the aileron
servo 3/4-inch (19mm) from the edge that is
closest to the wing tip as shown. The edge of the
aileron servo mount will align with these marks
when it is installed. Center the mount fore/aft in the
opening for the aileron servo.
3. Lightly sand the aileron servo mount using
medium grit sandpaper. This will allow the glue to
penetrate into the mount and provide a better bond
between the mount and wing.
DO NOT remove the string from the wing. The
string will be used to pull the aileron servo
lead through the wing later in this section.
6 E-flite BAe Hawk ARF Assembly Manual
4. Mix a small amount of 6-minute epoxy and
brush it onto the side of the aileron servo mount
that was sanded in the previous step. Position the
mount in the wing as shown in Step 2 and allow
the epoxy to fully cure before proceeding.
6. Position the aileron servo in the servo mount as
shown in the image.
8. Tie the string around the end of the servo
lead as shown.
While waiting for the epoxy to dry on one wing panel,
you can step through the previous steps to glue the
remaining servo mount into the opposite wing panel.
5. Plug the aileron servos into the receiver and use
the transmitter to center the servos. Also check that
they are operating correctly at this time. Remove
the standard servo horn and install the single-sided
servo arm that was supplied with the servo.
7. Use a #1 Phillips screwdriver and two 2.5mm
x 10 sheet metal screws to secure the servo in the
servo using the servo mounting strap. Install one
screw and only turn it one or two turns, then install
the second screw. Make sure the strap has even
pressure at both the front and back of the servo.
Use care when installing the servo mounting strap.
Over-tightening the strap could stress the wing sheeting
and even push the servo through the top of the wing.
9. Carefully pull the aileron servo lead through the
wing using the string tied to it in the previous step.
10. Repeat Steps 1 through 9 to install the
remaining aileron servo.

Aileron Linkage Installation
Required Parts
Aileron pushrod keeper (2)
Aileron pushrod wire, 5 15/16-inch (151mm) (2)
Servo cover (2)
Aileron control horn (2) Clear tape
Required Tools and Adhesives
Side cutters Medium CA
Pin drill Drill bit: 5/64-inch (2mm)
Felt-tip pen Hobby knife w/#11 blade
Needle-nose pliers Hobby scissors
Medium grit sandpaper
1. Using a felt tip pen mark the aileron for the
aileron control horn. The horn is positioned 13/32inch (10mm) back from the hinge line of the
aileron. Also mark a center line that corresponds
with the aileron servo horn.
2. Position the control horn so it is aligned with the
marks made in the previous step. Lightly press the
control horn down to leave the indentations of the
prongs in the aileron. The control horn should be
aligned 90 degrees to the aileron hinge line in line
with the servo arm.
3. Use side cutters to remove 3/32-inch (2mm)
from the prongs of the servo horn so they do not
extend through the top of the aileron when the
control horn is installed.
4. Use a pin drill and 5/64-inch (2mm) drill bit
to drill the two holes for the control horn prongs.
Use care not to drill into the aileron too far and
accidentally drill through the top of the aileron.
Use low-tack tape to tape the aileron in position so it
doesn’t move during the linkage installation. This will
make the procedure go easier and will help in keeping
things aligned during the linkage installation process.
8 E-flite BAe Hawk ARF Assembly Manual
5. Position the control horn on the aileron and
trace the outline of the horn onto the wing using a
felt-tip pen.
7. Use medium CA to glue the aileron control
horn to the aileron. Allow the CA to fully cure
before proceeding.
9. Slide the pushrod keeper onto the aileron
pushrod wire as shown in the photo.
6. Use a hobby knife and a new #11 blade to
remove the covering 1/16-inch (1.5mm) from the
inside of the lines drawn in the previous step. Use
care not to cut into the underlying wood of the
aileron.
Use a paper towel and rubbing alcohol
to remove the lines from the aileron once
the covering has been removed.
8. Insert the Z-bend of the aileron pushrod into the
hole of the servo arm that is farthest from the center
of the arm.
There are two pairs of pushrod keepers included
with your aircraft. The correct ones for the aileron
pushrods will have larger holes than the elevator
pushrod keepers. If the keepers are difficult to
slide on the wire, try a different keeper, as they
should slide easily on the pushrod wire. Make
sure that these pushrod keepers are slid on to the
pushrods before making the bend in Step 11.
10. Make sure the aileron servo has been centered
using the radio system. Mark the pushrod using a
felt-tip pen where it crosses the hole in the aileron
control horn that is one up from the bottom of the
horn as shown.
9E-flite BAe Hawk ARF Assembly Manual
11. Use needle-nose pliers to bend the pushrod
wire 90 degrees at the mark made in the previous
step. After making the 90-degree bend, cut the
excess wire off of the pushrod leaving 1/4-inch
(6mm) from the bend in the pushrod.
12. Insert the bend into the hole in the aileron
control horn that is one up from the bottom of the
horn as shown.
13. Use needle-nose pliers to open the pushrod
connector wire enough that it can be fit onto the
pushrod wire.
14. Make sure the hole in the keeper fits onto
the pushrod wire. The keeper should fit close
to the control horn and not be bent when
installed correctly.
15. Use hobby scissors to trim the aileron control
horn servo cover on the lines that are molded into
it. Use medium grit sandpaper to clean up and
rough edges and to round the corners slightly on
the cover.
10 E-flite BAe Hawk ARF Assembly Manual
16. Cut four pieces of clear tape from the supplied
tape using scissors and use them to attach the servo
cover to the wing. Make sure the servo can operate
without binding on the servo cover.
You can also glue the cover to the wing using canopy
glue or epoxy. The only drawback is that if you ever
have a problem with the servo you may damage the
cover and wing covering removing the servo cover.

1. Secure a 9-inch (228mm) servo extension to
the aileron servo lead. Use thread or dental floss
to secure the two together so they do not become
unplugged inside the fuselage.
2. Slide the short and long wing rods into one
of the wing panels. The longer wing rod will be
inserted near the trailing edge of the wing, and the
shorter rod toward the leading edge of the wing.
3. Slide the wing tubes into the fuselage.
Make sure to guide the aileron servo extension
into the fuselage so the wing can fit tight against
the fuselage.
17. Repeat Steps 1 through 16 to install the
remaining aileron servo linkage.
You can also use large heat shrink to secure the
extension to the servo lead. Be careful not to get
the heat shrink too hot as it could distort the plug.
