This instruction manual is designed to guide you through the entire final assembly process of your new Wattage
Hawk EP ARF in the least amount of time possible. Along the way you'll learn how to properly assemble your new
airplane and also learn many tips that will help you in the future. We have listed some of our recommendations
below. Please read through them before going any further.
The Hawk EP is constructed of blow-molded plastic and foam. It is very important that you use
no solvents, Cyanoacrylate (C/A) glue, or paint that can damage foam. If any of these
chemicals come in contact with the foam parts, the parts will be destroyed and will not be
covered under warranty. Use only epoxy where glue is required. If you decide to paint the
Hawk EP, use a paint that will not attack foam and always test on a scrap piece first.
Please read through each step before starting as-
sembly. You should find the layout very complete and
simple. Our goal is to guide you through assembly
without any of the headaches and hassles you might
expect.
There are check boxes next to each step. After you
complete a step, check off the box. This will help you
keep from losing your place.
Cover your work table with brown paper or a soft
cloth, both to protect the table and to protect the indi-
vidual parts.
Keep a couple of small bowls or jars handy to put
the small parts in after you open the accessory bags.
We have included a glossary of terms beginning
on page # 14. Check it out if you come across a term
that is unfamiliar to you.
We're all excited to get a new airplane in the air,
but take your time. This will ensure you build a straight,
strong and great flying airplane.
If you come across this symbol
, it means that
this is an important point or an assembly hint.

The following section describes our recommendations to help you in deciding which types of accessories to purchase for
your new Wattage Hawk EP ARF. We have tested all of these items with the airplane and found that these products will
offer the best in performance, reliability and economy.
OUR RECOMMENDATIONS
The Hawk EP will require a minimum 3 channel radio control system with two micro servos. The radio system we
recommend is the Hitec Focus 3 AM radio with 2 HS-81 Micro servos. This radio system includes two micro servos, a
three channel mini receiver, servo mounting hardware and a setup guide.
If you want to purchase a radio system that will be more upgradeable in the future, a four or more channel radio with
two micro servos and a mini or micro receiver will work well. If you decide to go this way, our recommendation would
be to use the Hitec Flash 4X Glider FM Computer radio with 2 HS-81 Micro servos. This is a very good radio system
that offers the capability to grow as your experience grows.
If you already have a standard radio system, you will need to purchase an after-market mini or micro receiver and two
micro servos. If you need to purchase these items we recommend the Hitec Micro 555 receiver (part # 759118) and two
Cirrus CS-21 Micro servos (part # 444227).
RADIO SYSTEM
Our Recommendations Cont.

To operate the motor, we suggest using a proportional electronic speed control (ESC) that features battery eliminator
circuitry (BEC) and auto-cutoff. BEC allows you to eliminate the receiver battery and uses the flight battery to control
both the motor and the radio system. Eliminating the receiver battery provides a great weight savings which effectively
increases performance. The auto-cutoff feature turns off the motor when the voltage in the battery drops too low to
operate the radio system safely. This guarantees safe operation throughout the entire flight. To obtain these features, we
suggest using the Wattage IC-380 ESC. You can also upgrade to the Wattage IC-14 ESC (part # 128484). This ESC is
smaller and lighter, and includes special tabs that hook directly to most speed 380 motors. This means there isn't any
soldering required and you won't experience current loss because of poor connectors. If you decide not to use a propor-
tional electronic speed control, an electronic switch like the Hitec Motor Controller SP-1003 (part # 759850) is an
economical way to turn the motor on and off. This switch does not offer any proportional speed, only off or full power.
The battery you choose should be a 6 cell (7.2Volt) to 8 cell (9.6Volt) 650Mah Nickel Cadmium (NiCd) battery pack or a
6 cell to 8 cell 650Mah Nickel Metal Hydride (NiMh) battery pack. The 8 cell battery pack will provide more power,
resulting in higher speeds and better climb-out, but weigh more than the 6 cell battery pack. The Nickel Metal Hydride
battery pack will give you about 25% longer run-time, but not quite as much power.
ELECTRONIC SPEED CONTROL
FLIGHT BATTERY
Because the flight battery is small and it powers both the motor and the radio system, we suggest using an Automatic Delta
Peak Charger such as the Promax Activator Digital Peak Charger (part # 885650) to charge the flight battery. It is vital to
the Hawk EP's flying performance that the battery pack be fully charged every flight, so using a peak charger is very
important.

The heavy duty Scotch tape can be purchased in any drug store or supermarket. You don't have to
use Scotch brand; however, because it helps strengthen the wing, it's important that the tape have
a high tensile strength. The 3M/Scotch part number is 105.

Before beginning assembly, we recommend that you
first break in the motor. Taking the time to do this now
will do a couple of things. First, it will improve the per-
formance and life of the motor and, second, it will give
you a chance to test your radio system, ESC and flight
battery before installing them into the airplane.
1) Lay the motor, flight battery, charger, radio sys-
tem and electronic speed control onto your work table.
2) Charge the flight battery using your peak charger,
following the instructions that were provided with the
charger. Install 8 AA batteries into the Focus 3 transmitter.
3) Plug the two servo leads and the ESC lead into
their proper slots in the receiver. Carefully solder the ESC
motor leads to the back of the motor. The mounting tab
with the red dot next to it is the positive tab.
MOTOR BREAK-IN
TOOLS AND SUPPLIES REQUIRED
Needle Nose Pliers
Trinity Break-In Drops
Performance Plus Motor Spray
Paper Towels
BREAKING IN THE MOTOR
You will still be able to install the motor into the air-
plane even with the ESC soldered in place. If you are
using the Wattage IC-14 ESC, soldering is not required.
4) Set the motor between the handles of a pair of
needle nose pliers and secure the motor to the handles
using a couple of small rubber bands. This will keep the
motor secure enough for the break-in procedure. See
photo # 1 below.
Photo # 1
Don't use the rubber bands included with the kit. They
are used to hold the wing in place and you don't want
them to be damaged by any solvents used for break-in.
5) Turn on the transmitter and plug the flight bat-
tery into the speed control. Make sure the throttle is at
idle and the motor is turned off.
6
8) Using a couple of paper towels, wipe off the ex-
cess motor spray and oil.
9) Slowly turn on the motor. Position the throttle
lever to about 1/3 throttle and let the motor run. While
the motor is running, apply a light spray of motor spray
inside the motor openings once every minute, followed
by a small drop of Break-In Drops on each of the bush-
ings. Do this until the battery is fully discharged.
If you have chosen to use an on-off only motor con-
troller, complete the same process but only run the motor
in two-minute intervals, letting the motor cool between
each interval.
10) After the battery has discharged and the motor
has stopped, spray motor spray through the motor open-
ings until the fluid runs clear. Apply a couple of drops of
Break-In Drops to the bushings and wipe away all of the
excess using paper towels.
1) Test fit the wing panels together. They should
fit together with few or no gaps between the two, and the
leading edges and trailing edges should line up evenly.
If the wing panels don't fit together properly, care-
fully sand the ends of the wing panels straight using 220
grit sandpaper with a sanding block. Be careful not to
change the dihedral angle.
2) Mix a generous amount of Kwik Bond 5 Minute
Epoxy. Apply a thin layer to the ends of both wing pan-
els, making sure that you cover all of the gluing surfaces.
3) Fit the wing panels back together and realign
them. Remove any excess epoxy using a paper towel and
rubbing alcohol. Hold the wing panels together firmly
until the epoxy cures.
APPLYING THE WING REINFORCEMENT
4) After the epoxy has fully cured, apply a strip of
heavy duty Scotch tape to the bottom of the wing, over
the center section joint, from the leading edge to the trail-
ing edge. See photo # 3 below.
5) Apply one long strip of heavy duty Scotch tape
to the bottom of the wing. Apply the tape down the middle
of the wing, parallel with the trailing edge, from wing tip
to wing tip.
6) Fold the wing trailing edge reinforcement board
in half lengthwise. Remove it from its protective back-
ing and carefully stick the reinforcement board over the
trailing edge of the wing at the center section. See photo
# 4 below.
6) With the motor turned off, test the operation of
the two servos. Both servos should move when you move
the control stick.
7) Carefully spray a couple of light sprays of Per-
formance Plus Motor Spray inside the motor openings and
apply a small drop of Trinity Break-In Drops onto each of
the two motor bushings. See photo # 2 below.

INSTALLING THE WING TUBES
ITEMS REQUIRED
{1} Molded Plastic Fuselage
{1} 4mm x 60mm Aluminum Tube
{1} 4mm x 70mm Aluminum Tube
{4} Nylon Sleeves
{4} Rubber Bands
7) Remove the wing center section reinforcement
board from its protective backing. Carefully stick the re-
inforcement board to the top of the wing, making sure
that it's centered over the wing's center section. The back
edge should be just ahead of the trailing edge reinforce-
ment board. See photo # 5 below.
1) Using a modeling knife, carefully cut out the parts
of the fuselage from over the cockpit area and the wing
saddle. Use the molded scribe lines as a guide.
2) Using a modeling knife, remove the plastic from
over the four molded wing mounting tube holes in the
fuselage sides.
3) Using 220 grit sandpaper, carefully roughen the
surface of the fuselage (on the inside) around the four
holes. Roughen both aluminum tubes and the outer sur-
face of all four nylon sleeves. This will make the epoxy
adhere better to the parts when you glue them into place.
Photo # 5
Because the two strips of tape and the two pieces of
reinforcement board add a lot of strength to the wing, it is
important that they all be pressed firmly to the surface of
the wing.
4) Push one nylon sleeve into each of the four holes.
Slide the 4mm x 70mm aluminum tube through the two
front holes and slide the 4mm x 60mm aluminum tube
through the two rear holes. See photo # 6 below.
Photo # 6
5) Mix a small amount of Kwik Bond 5 Minute
Epoxy. Center both of the aluminum tubes and glue them
into place by applying a small dab of epoxy to the tube
and sleeve where they meet the fuselage sides. Apply the
epoxy from inside the fuselage. Allow the epoxy to fully
cure before proceeding.
MOUNTING THE WING
6) Place the wing into the wing saddle, aligning the
centerline of the wing with the centerline of the fuselage.
Hold the wing securely in place using four rubber bands -
two per side.

{12}1mm x 4mm Wood Screws
ALIGNING THE
HORIZONTAL STABILIZER
Do not epoxy the stabilizers into place. Because of
the plastic that the fuselage is molded from, even rough-
ening the surface will not allow the epoxy to adhere strong
enough to hold the stabilizers securely.

2) Remove the two pieces of horizontal stabilizer
reinforcement board (tapered shape) and stick them to the
top and bottom of the horizontal stabilizer mounting area.
The back edge of each reinforcement board should be flush
with the back edge of the mounting area.
Notice how the shape of the reinforcement board
matches the shape of the stabilizer mounting area. See
photo # 8 below.
3) Using a drill with a 1/16" drill bit, carefully drill
eight holes through the stabilizer mounting flanges on the
fuselage. Drill two holes through each flange, equally
spaced apart, on the top of the fuselage and two holes
through each flange on the bottom of the fuselage. See
photo # 9 below.
4) Using a modeling knife, carefully trim away the
extra plastic left over from drilling the holes.
5) Slide the horizontal stabilizer into place in the
fuselage. Push the stabilizer as far forward as possible,
aligning the outer edges of the reinforcement board with
the outer edges of the mounting flanges.
6) With the wing mounted to the fuselage and the
stabilizer in place, look carefully from the front of the
fuselage at both the wing and the stabilizer. When aligned
properly, the stabilizer should be level with the wing. If it
is not level, use a modeling knife and/or 220 grit sandpa-
per and adjust the mounting flanges until the correct
alignment is achieved. See figure # 1 below.
Figure # 1
7) Now check to make sure that the tips of the sta-
bilizer are equal distances from the tips of the wing. Use
a ruler and measure from one wing tip to the stabilizer tip
on the same side. Do this for both sides. When the stabi-
lizer is aligned properly, both of these measurements
should be the same. See figure # 2 below.
Figure # 2
8) When satisfied with the alignment, use a couple
of pieces of masking tape to hold the stabilizer in place.
9) Install and lightly tighten the eight 1mm x 4mm
wood screws to hold the stabilizer firmly in place. Make
sure that each wood screw threads into the reinforcement
board.
To help start the screws, gently poke a pilot hole into
the reinforcement board with the tip of a modeling knife.
1) Using a modeling knife, carefully cut out each
side of the horizontal stabilizer mounting slot in the back
of the fuselage. See photo # 7 below.
Photo # 7
Photo # 8
Photo # 9
Drill the eight holes at the inside edges of the flanges,
up against the fuselage sides. This will ensure that the
wood screws won't miss the reinforcement board when
you install them later.

10) Using a modeling knife, carefully cut out the
vertical stabilizer mounting slot in the top of the fuselage.
11) Remove the two pieces of vertical stabilizer re-
inforcement board and stick them to the right and left sides
of the vertical stabilizer mounting area.
Notice how the shape of the reinforcement board
matches the shape of the stabilizer mounting area. See
photo # 10 below.
12) Slide the vertical stabilizer into place. Push the
stabilizer forward until its leading edge is even with the
molded leading edge in the fuselage.
13) Using a modeling knife, remove the 1/4" long
portion of the vertical stabilizer that hangs past the back
edge of the fuselage.
14) While holding the vertical stabilizer in place,
use a builder's triangle to check and ensure that it is aligned
90º to the horizontal stabilizer. If it does not line up, use
a modeling knife and/or 220 grit sandpaper and retrim the
mounting flanges until the correct alignment is achieved.
See figure # 3 below.
Figure # 3
15) Remove the vertical stabilizer. Using a drill with
a 1/16" drill bit, carefully drill four holes through the
mounting flanges, equally spaced apart, two on each side.
16) Using a modeling knife, carefully trim away the
extra plastic left over from drilling the holes.

5) Install the servo tray into the fuselage. To align
the servo tray properly, the back edges of the servo tray
mounting sides should be pushed up against the front of
the aluminum wing mounting tube, and the tops of the
servo tray mounting sides should be pushed up against
the bottom of the wing saddle. See photo # 17 below.
6) When satisfied with the alignment, press the
servo tray sides firmly into place to secure the tray into
the fuselage.
INSTALLING THE SERVOS
7) Install the rubber grommets and brass collets onto
each of the servo mounting lugs.
8) Test fit your two micro servos into the servo tray.
If necessary, use a modeling knife to enlarge the hole in
the servo tray to accommodate the two servos. The ser-
vos should fit tightly in the servo tray.
Both of the servos' output shafts should face toward
the front of the fuselage.
9) Mount the servos to the servo tray using the servo
mounting screws provided with your servos. Use the tip

PUSHROD INSTALLATION
TOOLS AND SUPPLIES REQUIRED
ITEMS REQUIRED
{2} Threaded Pushrod Wires
{2} Nylon Control Horns w/Backplates
{2} Nylon Clevises
# 0 Phillips Head Screwdriver
Modeling Knife
Wire Cutters
Magnum Z-Bend Pliers
Electric or Hand Drill
1/16" Drill Bit
Straight Edge Ruler
Pen or Pencil
INSTALLING THE CONTROL HORNS
1) Using a modeling knife, cut one thin slot through
the middle of each molded recess in both the elevator and
the rudder. Cut the slot large enough for the ends of the
control horns to pass through.
2) Push one control horn through each slot. The
end of the elevator control horn should be on the bottom
of the elevator and the end of the rudder control horn
should be on the left side of the rudder.
3) Making sure the flat portion of the backplates
face away from the control surfaces, push the backplates
over the ends of the control horns until you hear them
"click" into place. See photo # 19 below.

INSTALLING THE PUSHRODS
4) Using a modeling knife, carefully cut out the rud-
der pushrod exit hole (the back of the molded fairing) in
the top of the fuselage. Make the cutout large enough for
the pushrod wire to pass through easily.
5) Plug in your receiver, ESC, flight battery and
elevator and rudder servos. Turn on the radio system
and center both of the servos using the trim levers on the
transmitter.
6) Thread one nylon clevis onto each of the two
threaded pushrod wires. Thread the clevises on far enough
to leave room for adjustments later.
Don't push the backplates too far down over the con-
trol horns or you might crush the foam.
12
8) Place a "single arm" servo horn onto the eleva-
tor servo, making sure that the servo horn is centered and
points toward the fuselage side. The arm should have at
least three holes in it.
9) With both the servo horn and the elevator cen-
tered, use a pen and draw a mark on the pushrod wire
where it crosses the third hole out from the center of the
servo horn.
10) Unsnap the clevis and remove the pushrod wire
from the fuselage. Using Magnum Z-Bend Pliers, make a
Z-Bend in the pushrod wire at the mark you drew.
11) Slide the pushrod wire back into place and snap
the clevis into the control horn. Attach the servo horn to
the Z-Bend, then attach the servo horn to the servo, mak-
ing sure it's centered. Install and tighten the servo horn
retaining screw, provided with your servo, to secure the
servo arm into place. See photo # 21 below.
FINAL ASSEMBLY
TOOLS AND SUPPLIES REQUIRED
# 0 Phillips Head Screwdriver
Modeling Knife
Electric or Hand Drill
1/16" Drill Bit
5/64" Drill Bit
Pen or Pencil
Scissors
ITEMS REQUIRED
{1} Molded Clear Canopy
{1} Velcro Strip
{1} Decal Sheet
{2} 2mm x 5mm Wood Screws
INSTALLING THE RECEIVER, FLIGHT
BATTERY AND ESC
1) Using a modeling knife, cut out the on-off switch
and arming switch holes in the left side of the fuselage.
2) Install the on-off switch and arming switch us-
ing the hardware provided with your ESC.
If your ESC does not come with mounting screws,
use # 2 sheet metal screws and # 2 flat washers to install
the switch.
3) Using a pair of scissors, cut the piece of Velcro
in half. Using one piece of Velcro, mount the receiver to
the fuselage floor in front of the servo tray. Uncoil the
antenna and feed it out the elevator pushrod exit hole in
the back of the fuselage. Use a piece of Scotch tape to
hold it in place.
4) If you haven't already done so, connect the mo-
tor leads from your ESC to the tabs on the motor.
5) Mount the battery onto the fuselage floor, in front
of the receiver, using the second piece of Velcro. See
figure # 4 below.
7) Slide one of the pushrod wires up through the
back of the fuselage, making sure that the wire enters the
servo compartment above the servos. Snap the clevis into
the elevator control horn. See photo # 20 below.

Photo # 21
You will have to enlarge the hole in the servo arm
using a 1/16" drill bit, so that the pushrod wire will fit
through; and, depending on the length of the servo horn,
you may have to cut it shorter so that it doesn't hit the side
of the fuselage.
12) Install the rudder pushrod wire using the same
technique as with the elevator pushrod wire. The Z-Bend
should be installed into the third hole out from the center
of the servo horn as well.

The location of the battery shown above is approxi-
mate. You may have to move it fore or aft to balance the
airplane in the next section.

MOUNTING THE CANOPY
1) Using a pair of scissors, carefully cut out the clear
canopy along the molded scribe line.
2) Set the canopy into the molded recess in the fu-
selage. Use a couple of pieces of masking tape to hold
the canopy in place.
3) Using a drill with a 1/16" drill bit, drill two pilot
holes through the canopy sides (one on each side) and
into the fuselage. Remove the canopy and enlarge only
the holes in the canopy using a 5/64" drill bit.
4) Set the canopy back into place and realign it.
Install and tighten the two 2.5mm x 5mm wood screws to
hold the canopy securely in place. See photo # 22 below.
APPLYING THE DECALS
1) Working with one decal at time, use a pair of
scissors and carefully cut out the decal along its outer
edges.
Notice that next to each "feather" decal is printed its
proper location on the airplane. This will help you place
them in the proper position on the airplane.
2) Remove the protective backing from the decal
and stick the decal to the airplane. Lightly rub the decal
with your finger to remove any trapped air from beneath
it. See photo # 23 below.

If any air bubbles form in the decal you can "prick"
the bubble with a straight pin to release the air.
BALANCING
TOOLS AND SUPPLIES REQUIRED
Straight Edge Ruler
Masking Tape
BALANCING THE HAWK EP
1) It is critical that your airplane be balanced cor-
rectly. Improper balance will cause your airplane to lose
control and crash.
CONTROL THROWS
1) We recommend setting up the Hawk EP using
the control throws listed above. These control throws are
suggested for initial test flying.
This location is recommended for initial test flying. The
C.G. can be moved aft up to 1/4", but it is not recom-
mended that the C.G. be located any farther back than
1-7/8" behind the leading edge of the wing.
The Hawk EP should be balanced with the flight bat-
tery mounted in the fuselage.
2) Install the wing onto the fuselage and place two
short pieces of masking tape on the bottom of the wing,
1-5/8" back from the leading edge, at the fuselage sides.
3) Place your fingers on the masking tape and care-
fully lift the airplane. If the nose of the airplane falls,
the airplane is nose heavy. To correct this, move the
flight battery back just far enough to bring the airplane
into balance. If the tail of the airplane falls, the airplane
is tail heavy. To correct this, move the flight battery
forward only enough to bring the airplane into balance.
When balanced correctly, the airplane should sit level or
slightly nose down when you lift it up with your fingers.
Once you have flown and become familiar with the
flight characteristics of the Hawk EP, the balance point
(C.G.) can be moved aft up to 1/4" to change the flight
performance. Moving the balance point back will cause
the airplane to be more responsive, but less stable. Do
not fly the Hawk EP beyond the recommended bal-
ance range or an uncontrollable crash could result!
The Center of Gravity is located 1-5/8" back
from the leading edge of the wing, at the
fuselage sides.
TEST FLYING
Elevator: 3/8 up 3/8 down
Rudder: 3/8 right 3/8 left
14
3) You can increase or decrease the control throws
by moving the pushrod wires in or out from the center of
the servo arm. Moving the pushrod wires out will in-
crease the control throws. Moving the pushrod wires in
will decrease the control throws.
LAUNCHING THE HAWK EP
The Hawk EP is a gentle flyer; however, because of
its speed, it is not recommended for the beginning flier.
To hand-launch the hawk EP, gently grasp the fuse-
lage between your thumb and forefingers at the C.G.
location. Hold the airplane above shoulder level and turn
on the motor to full power. With the motor running at full
power, gently toss the Hawk EP straight ahead. Do not
throw it up at an angle. Let the airplane fly straight and
level to pick up airspeed, then climb up to your desired
altitude. Be careful not to climb too steeply after hand-
launching or you could stall the airplane.
2) After you have become familiar with the flying
characteristics of the Hawk EP, you may want to increase
the control throws to the settings listed below.

GLOSSARY OF TERMS
Center of Gravity: Most commonly referred to as the
C.G. or balance point, it is the point at which the airplane
is in complete balance in all three axes.
Clevis: Part of the control system, either made out of
nylon or metal. It connects the pushrod wire to the con-
trol horn mounted on the control surface.
Control Horn: Part of the control system, the control
horn is mounted to the control surface. It allows the push-
rod to be connected to the control surface. Almost all
control horns are adjustable to allow for more or less con-
trol surface movement.
Cycling: The act of fully charging and discharging the
flight battery. Cycling the battery increases performance
and duration.
Dihedral: The upward angle of each wing half. Dihe-
dral creates more stability which makes learning to fly
much easier.
Elevator: The elevator is the control surface on the back
of the airplane that moves up and down. This surface
controls pitch.
Epoxy: A two-part glue containing a resin and a hard-
ener. Epoxy is available in several drying times and is
stronger than C/A glue. Epoxy is used in high stress ar-
eas such as where wing halves are joined.
ESC: An acronym for Electronic Speed Control. See
Motor Controller below.
Horizontal Stabilizer: Mounted in the rear of the air-
plane, the stabilizer works with the elevator to control
pitch.
Motor Controller: Usually called an electronic speed
control (ESC), the motor controller controls the speed of
the motor. Motor controllers can also be simple on and
off switches.
Peak Charger: A type of battery charger that uses a mi-
croprocessor to sense when the flight battery is fully
charged. Once peak charged, the charger shuts off so the
battery does not overcharge.
Pushrods: They connect between the control surface and
the servo, transferring the movement of the servo directly
to the control surface.
Receiver: The part of the radio system that receives the
signals from the transmitter.
Rudder: The rudder is the control surface on the back of
the airplane that moves right and left. This causes the
nose of the airplane to yaw right and left.
Servo: The part of the radio system that produces the
movement necessary to move the control surfaces. The
servo includes a small motor, gears and a circuit board.
Transmitter: The part of the radio system that you con-
trol. It transmits the control inputs to the receiver, which
transfers that information to the servos.
Vertical Stabilizer: Mounted on the rear of the airplane,
it works with the rudder to turn the airplane. It also gives
the airplane vertical stability.
Wing Hold Down Dowel: A length of hardwood dowel
or aluminum inserted through the fuselage at the front and
back of the wing saddle. It is an anchor for the rubber
bands that hold the wing onto the fuselage.
Wing Saddle: The portion of the fuselage where the wing
mounts on to.
Z-Bend: This is a special bend made in the pushrod wire.
While it cannot improve your ability to make adjustments,
the Z-Bend is the most secure way to attach the pushrod
wire to the servo horn.
