19

Section 6: Centering the Control Surfaces

Required Parts

• Assembled airframe

Required Tools and Adhesives

• Ruler

Checking the Elevator

Center the elevator stick and trim. If necessary, detach the
clevis from the control horn and thread the clevis in or out
on the elevator pushrod until the elevator is aligned with
the stabilizer as shown. Remember to attach the clevis
back in the center hole as described earlier in the manual.

Checking the Rudder

Center the rudder stick and trim. If necessary, detach the
clevis from the control horn and thread the clevis in or out
on the rudder pushrod until the rudder is aligned with the
fin as shown. Remember to attach the clevis back in the
center hole as described earlier in the manual.

Checking the Ailerons

Center the aileron stick and trim. If necessary, detach the
clevis from the control horn and thread the clevis in or out
on each aileron pushrod until the ailerons are aligned with

the wing as shown. Don't forget to align both ailerons at

this time. Remember to attach the clevis back as described
earlier in the manual.

20

Section 7: Wing Installation

Required Parts

• Wing assembly • Fuselage assembly

• Rubber band (10)

 Step 1

Locate the aileron extension that is inside the fuselage.
Align the colors from the aileron servo lead with the
extension so they match, then plug them together.

 Step 3

Install a second set of rubber bands on the wing
as shown.

 Step 4

Continue installing a total of six or more of the rubber
bands, alternating the direction of each set until they have
all been installed.

 Step 2

Start securing the wing to the fuselage by installing two of
the rubber bands.

Hint: Always start with the cross rubber
bands. This will keep the wing from
twisting on the fuselage when installing
the remaining rubber bands.

Hint: Always end the rubber band installation
by installing the cross rubber bands last.
They will help in keeping all the other rubber
bands in position on the wing dowels.

Hint: After flying, store your rubber bands in
a bag with a small amount of baby powder.
This will soak up the fuel that is on the
rubber bands, making them last longer.

Section 13: Binding

Binding is the process of teaching the receiver the specific
code of the transmitter so it will connect to that specific
transmitter which it is bound to. The transmitter and
receiver for your Alpha 40 RTF has already been bound,
but this section has been included as reference. The
AR500 receiver must be bound to the transmitter before it
will operate. Once bound, the receiver will only connect to
that transmitter.

 Step 1

Remove the receiver cover in the fuselage to access
the receiver.

 Step 2

Temporarily remove the power plug from the battery/bind
port in the receiver and plug it into the aileron extension.
Plug the bind plug into the battery/bind port in the
receiver where the power lead was.

24

Section 13: Binding

 Step 3

Turn on the receiver switch. The LED on the receiver
should be flashing, indicating that the receiver is ready
to bind.

 Step 4

Establish the desired failsafe stick positions: normally low
throttle and flight controls neutral.

 Step 5

Pull and hold the trainer switch on the top of the
transmitter while turning on the power switch. Turning
on the switch will place the transmitter into bind mode.
Within a few seconds the system should connect and the
LEDs on the front of the transmitter will flash. The LED
on the receiver should go solid indicating the system has
connected. Once the system has connected release the
trainer switch.

Note: Do not hold the trainer switch and turn
on the power during normal operation or the
receiver will become unbound and the entire
binding process will have to be done again.

25

Section 13: Binding

 Step 6

After the system is bound, turn off the power on the
transmitter and receiver. Then remove the bind plug from
the receiver and store it in a convenient place.

 Step 7

Unplug the power lead from the aileron extension and
plug it back into the power/bind port of the receiver. Turn
on the transmitter and receiver to confirm that it is bound
and working properly. Then replace the receiver cover in
the fuselage.

Check the movement of the rudder using the transmitter.
When the left stick is moved left, the rudder should also
move left. This will cause the aircraft to turn left while on
the ground and to yaw left while in flight.

Check the movement of the rudder using the transmitter.
When the rudder/throttle stick (left side of the transmitter)
is moved right, the rudder should also move right. This
will cause the aircraft to turn right while on the ground
and to yaw right while in flight.

Section 14: Checking the Control Surface Movement

Reversing Direction of Flight Controls

If you find any of the control surfaces moving in the
opposite direction (example shown below), you will
need to use the Servo Reversing feature of your
radio system. Follow the instructions included with
your radio to change the servo reversing of the offending
control surface.

Section 15: Hi/Lo Rate

The DX5e offers a high/low rate function on aileron, elevator and rudder. When the HI/LO rate switch is in the upper

position or “HI” position, 100% travel is achieved on the aileron, elevator and rudder channels. When the switch is in the
lower position, a reduced travel of 50% is achieved on the aileron, elevator and rudder channels. This is useful allowing

the aircraft to have a high control rate (switch in the “HI” position) for aggressive maneuvers and a low control rate
(switch in “LO” position) for smooth, precise maneuvers.

• High 100% rate on aileron, elevator and rudder

• Low 50% rate on aileron, elevator and rudder

Section 16: Setting the Control Throws

Required Parts

• Transmitter • Assembled airframe

Required Tools and Adhesives

• Ruler

The control throws from the factory are
preset in the transmitter. This section
has been provided in case any servos or
control surfaces are replaced so the control
throws can be checked at a later date.

Rudder Throw

Use a ruler to check the amount of throw for the rudder.
Move the rudder stick fully and check the measurements.
Adjust the radio as necessary following the instructions
provided with the radio to achieve the following
measurement. The throw will measure:

Low Rate: 1/2-inch (13mm) (11 degrees)

High Rate: 7/8-inch (22mm) (20 degrees)

The throw is measured in both the right and left directions
as shown below.

Aileron Throw

Use a ruler to check the amount of throw for the aileron.
Move the aileron stick fully and check the measurements.
Adjust the radio as necessary following the instructions
provided with the radio to achieve the following
measurement. The throw will measure:

Low Rate: 1/4-inch (6mm) (8 degrees)

High Rate: 3/8-inch (10mm) (14 degrees)

The throw is measured in both the up and down directions
as shown below.

Note: The rudder throw is measured
at the bottom of the rudder.

32

Elevator Throw

Use a ruler to check the amount of throw for the elevator.
Move the elevator stick fully and check the measurements.
Adjust the radio as necessary following the instructions
provided with the radio to achieve the following
measurement. The throw will measure:

Low Rate: 5/16-inch (8mm) (10 degrees)

High Rate: 1/2-inch (13mm) (16 degrees)

The throw is measured in both the up and down directions
as shown below.

Section 17: Checking the Throttle Operation

Required Parts

• Fuselage assembly • Transmitter

Throttle Closed

Move the throttle stick and trim down to the fully closed
position as shown. The carburetor should close without
binding the throttle servo. If the servo binds, you will need
to adjust the clevis at the carburetor by threading it in or
out to eliminate any binding.

Throttle Open

Move the throttle stick and trim up, or the fully open,
position as shown. The carburetor should open without
binding the throttle servo. If the servo binds, you will need
to adjust the clevis at the carburetor by threading it in or
out to eliminate any binding.

33

Section 17: Checking the Throttle Operation

Throttle Set to Idle

Move the throttle stick down to the fully closed position.
Move the trim lever upward to open the carburetor roughly

1/16-inch (1.5mm). This will be the idle position for
your engine. The idle will be fine-tuned at the field so the

engine will idle reliably without stalling for slow flight and
landing procedures.

34

Section 18: Balancing Your Alpha RTF

In order for your Alpha 40 RTF to fly correctly, you will
need to check the balance of the plane with the fuel tank
empty. This is done by supporting the aircraft either using
your fingers or by using a balancing stand. Not checking
the balance can result in an aircraft that is difficult to fly,
which can lead to the possibility of crashing your model.

 Marking the Balance Point

The first step in balancing your Alpha 40 RTF is to mark
the location for the balance point. The ideal balance point
for the Alpha RTF is 2
the leading edge against the fuselage. If your plane is only
slightly out of balance, try placing the balancing stand

towards the nose or tail by 1/8-inch (3mm) and recheck

the balance. If it looks good and sits level, then you’re
good to go.

Balanced Correctly

Nose Heavy – Add Weight to Tail

 Lifting the Model and Observations

Make sure the Alpha RTF is balanced using either your
fingers or a balancing stand. Place or lift the airplane so
it is supported at the marks made in the previous step.
The plane will rest level when balanced correctly. If not,
weights must be added to correct any balancing problems.

Tail Heavy – Add Weight to Nose

35

Section 18: Balancing Your Alpha RTF

Adding Weights to Correct the Balance

Due to manufacturing differences, it is possible that the
Alpha 40 RTF may not be balanced properly. Weights can
be added to either the tail or the nose of your Alpha RTF

if it does not balance properly. Stick-on weights available

at your local hobby store are the easiest to use, and come
in sizes that are easily placed on your plane. Add just
enough weight as necessary to balance your plane. Once
the weight has been added, make sure it is secure and will
not fall off in flight.

Section 19: Flight Preparations

Flight preparations must be checked each time you travel
to the flying field. Because the Alpha RTF will encounter
a variety of situations, it is best to keep an eye on the
various components of your model to keep it in the best
flying condition.

 Checking the Frequency

When using a Spektrum radio system, follow the
guidelines for use of DSM radio systems at your
particular field.

 Checking the Controls

Before starting your engine, check to make sure the
controls are operating in the correct directions and the
linkages and surfaces are not binding anywhere. Also look
at the clevises and clevis retainers to make sure they are
secure and will not come loose or fail in flight.

 Fueling the Alpha RTF

Fill the fuel tank with the proper fuel. Fill the tank by
connecting the fuel pump to the line going to the needle
valve. Disconnect the fuel line attached to the pressure
fitting of the muffler; your tank is full when fuel begins to
run out of the pressure line. Reconnect the fuel lines to the
needle valve assembly and muffler.

Note: It is very important to reconnect
the lines to the correct place. If they
are reconnected incorrectly, the
engine will not run properly.

Section 20: How to Range Test the DX5e

Before each flying session, and especially with a new model, it is important to perform a range check. The DX5e
incorporates a range testing system which, when placed in the RANGE CHECK mode with the trainer switch activated and
held, reduces the output power, allowing a range check.

RANGE TESTING THE DX5E

 Step 1

With the model resting on the ground, stand 30 paces (approx. 90 feet) away from the model.

 Step 2

Face the model with the transmitter in your normal flying position. Pull and hold the trainer switch while toggling the
HI/LO Rate Switch four times. The LEDs will flash and the alarm will sound indicating the system is in range check mode.

 Step 3

You should have total control of the model with the trainer switch pulled at 30 paces (90 feet).

 Step 4

If control issues exist, call the Horizon Support Team at 1 [phone] or go to horizonhobby.com to find a local
Spektrum distributor in your country for service.

Section 21: Starting and Adjusting the Evolution Engine

FUEL

The Evolution Engine comes adjusted from the factory.
We recommend using high quality Cool Power Omega,
Hangar 9® AeroBlend™ or Power Master fuels containing

10 to 15% Nitro. The Evolution Engine has been test

run using these fuels. If another brand of fuel is used, it
may be necessary to slightly adjust the needle valves to
compensate for the differences in fuel.

GLOW PLUG

The Evolution Engine comes with a specially designed
“Super Plug” that prevents idle and transition flameouts.
The plug’s unique shape directs incoming fuel/air mixture
away from the plug element. When replacing the plug,
be sure to replace it with another Evolution Super Plug

(EVOGP1).

STARTING THE ENGINE

 Step 1

Fill the tank with the above-mentioned 10 or 15% fuel.

 Step 2

Reattach the fuel lines, making sure the vent and clunk
line are attached to the fuel nipple and the muffler
pressure nipple.

 Step 5

Attach the glow driver.

 Step 6

Turn the engine over using an electric starter.
The engine should fire within seconds of applying the

starter.

 Step 7

Allow the engine to idle for 30 seconds. Adjust the throttle
trim if necessary to achieve a constant slow idle.

 Step 8

With the glow driver still attached and a helper securely
holding the airplane, advance the throttle smoothly to full
throttle. The engine will transition to full rpm.

 Step 9

Reduce the throttle to idle and remove the
glow driver.

NEEDLE LIMITERS

In some conditions: Due to high altitudes, extreme
temperatures, etc., it may be necessary to slightly adjust

the idle and high-speed needle valves. The high- and low­speed needles have limiters that prevent over-adjustment.

Caution: Do not attach the glow driver yet.

 Step 3

With the throttle fully open, place your thumb over the

carburetor and rotate the prop clock-wise through 6

complete revolutions, thus priming the engine.

 Step 4

Close the throttle to the idle position and have a helper
hold your airplane.

38

Section 21: Starting and Adjusting the Evolution Engine

Low-Speed Needle AdjustmentHigh-Speed Needle Adjustment

If your engine starts from the above procedure, but won’t
reliably continue to run with the glow driver removed,
follow the steps above right.

The needle valves come preset from the factory. Extreme
conditions may require some minor adjustments. Note
that the needle adjustment range is limited, preventing
adjustment beyond the practical range.

STEP 2: LOW-SPEED NEEDLE ADJUSTMENT

The low-speed or idle needle valve, included with the

SetRight™ assembly, is preadjusted at the factory for best

performance. It may be necessary to fine-tune the low-

speed adjustment using the following procedure:

 Step 1

Start the engine and let it warm up, prior to attempting any

adjustments. Make sure that the high-speed adjustment
process is complete before attempting to adjust the low-

speed needle valve.

 Step 2

Close the throttle slowly. You will adjust the low-speed

needle setting by rotating the SetRight adjustment bar
clockwise to lean the engine and counterclockwise to
richen the engine.

Caution: Do not attempt to adjust the low-

speed needle valve while the engine is running.

STEP 1: HIGH-SPEED NEEDLE ADJUSTMENT

With the engine running, advance the throttle to full
throttle while a helper securely holds your airplane.
Carefully pinch and release the fuel line to temporarily
restrict the fuel flow.

Caution: Do not reach over the propeller
while the engine is running.

Correct: If the high-speed needle adjustment is correct,

the engine will increase rpm slightly (about 300 rpm) and
then die.

Too Rich: If the engine increases a lot (1,000 rpm or

greater), the high-speed needle is too rich and must be

leaned or turned clockwise.
Too Lean: If the engine doesn’t increase rpm and simply

dies, the high-speed needle is lean and must be richened

or turned counterclockwise.

 Step 3

The fuel mixture should be adjusted as follows: The fuel
mixture is too rich if, when opening the throttle rapidly,

the engine emits smoke and "stutters" or "stumbles."

Correct this by rotating the SetRight adjustment bar
clockwise in small increments. Continue this process until
the engine transitions smoothly from low rpm idle to high
rpm without hesitation upon opening the throttle rapidly.

 Step 4

The fuel mixture may be too lean if the engine stops at the
lowest idle position or it stops when the throttle is rapidly
opened from the idle position. Correct this by rotating
the SetRight adjustment bar counterclockwise in small
increments until the engine transitions smoothly without
hesitation upon opening the throttle rapidly from idle.

Engine Runs Inconsistently

ENGINE MAINTENANCE

After each flying session:

 Step 1

Fully drain the fuel from the tank.

 Step 2

Start the engine and run it until the fuel is
completely run out of the engine.

 Step 3

Try starting the engine three more times or until
it will no longer fire. This gets all the fuel out of
the engine.
At the end of each flying session, place several drops

(about 10) of after run oil (Evolution Engine's Blue Block
Rust Inhibitor, EVOX1000) should be applied into the

carburetor and the engine should be turned over for a
few seconds with the starter. This will prevent rust and
corrosion.

• Hole in fuel line

- Replace fuel line

• Bad or old fuel

- Replace with fresh fuel

40

Section 22: Maintaining Your Alpha 40 RTF

The following is a check list that you should follow
every time you have completed a flying session with
your Alpha 40 RTF. Doing so will keep your aircraft in
the best flying condition.

 Clean Up

After any flying session with your Alpha 40 RTF, you will
want to clean it up before loading it into your vehicle to
head home. Use glass cleaner and a paper towel to wipe
down the exterior of your plane, removing the fuel residue.
Remember a clean plane will last longer since the fuel
won’t be allowed to soak into any exposed wood.

 Checking the Propeller

Check to make sure the propeller is tightly secured to the
engine. If not, remove the spinner and use an adjustable

wrench to tighten it back down. If you have had any not­so-great landings, you will want to inspect the propeller

for any damage. Small nicks and scratches can quickly
become fractures, causing the propeller to be unsafe for
flight. Always carry a few spare propellers so a damaged
propeller can be replaced at the field, increasing your
flying time per trip to the field.

 Checking the Control Horns

Inspect the control horns to make sure they have not
crushed the wood of the control surface. If so, remove the

control horn screws to remove the control horn. Place 2–3

drops of thin CA into each of the screw holes. In addition,

use a T-pin to poke small holes in the covering in the area

where the control horn mounts, then saturate the area with
thin CA. This will harden the wood and give the control
horns a solid surface to be mounted to.

 Checking the Wheel Collars

Check the setscrews on the main and nose wheel collars,
as well as the wheel collars on the elevator linkage,
to make sure they are not loose. Use a hex wrench or
Phillips screwdriver as necessary to tighten the setscrews.
It is suggested if they loosen frequently to remove them,
apply threadlock to the setscrews, then secure the wheel
collars back into position.

 Check the Muffler Bolts

Use a 2.5mm hex wrench to make sure the bolts holding
the muffler onto the engine are tight and have not vibrated
loose during flight.

 Checking the Clevises

Inspect the aileron, elevator and rudder clevises to make
sure they are connected and in good working order. If
you find a clevis that is showing signs of wear or is
broken, replace it with a new clevis. Also check the nylon
connectors at the servo for any wear or damage. If they
look worn or in bad shape, replace them as well.

41

Section 22: Maintaining Your Alpha 40 RTF

 Check the Engine Mount Bolts

Remove the spinner and propeller from the engine.
Remove the exhaust stacks from the fuselage, and
then remove the cowling from the fuselage. Remove
the muffler from the engine, and then use a Phillips
screwdriver to make sure the four bolts securing the
engine to the mount are tight.

 Adjusting the Steering Trim

When adjusting the steering trim, do not use the trim on
the transmitter. The rudder trim on the transmitter is used
to trim the rudder while the aircraft is in flight. If you find
your model does not track straight during taxi, loosen
the screw and adjust the position of the nose wheel.
Remember to tighten the screw as soon as you have
changed the position of the nose wheel.

42

Safety Do’s and Don’ts for Pilots

• Ensure that your batteries have been properly

charged prior to your initial flight.

• Keep track of the time the system is turned on so

you will know how long you can safely operate
your system.

• Perform a ground range check prior to the initial

flight of the day. See the “Daily Flight Checks
Section” for information.

• Check all control surfaces prior to each takeoff.

• Do not fly your model near spectators, parking

areas or any other area that could result in injury
to people or damage of property.

Daily Flight Checks

 Step 1

• Do not fly during adverse weather conditions.

Poor visibility can cause disorientation and loss of
control of your aircraft. Strong winds can cause
similar problems.

• Do not point the transmitter antenna directly

toward the model. The radiation pattern from the
tip of the antenna is inherently low.

• Do not take chances. If at any time during flight

you observe any erratic or abnormal operation,
land immediately and do not resume flight until
the cause of the problem has been ascertained
and corrected. Safety can never be taken lightly.

 Step 5

Check the battery voltage on both the transmitter and

the receiver battery packs. Do not fly below 4.3V on the
transmitter or below 4.7V on the receiver. To do so can

crash your aircraft.

Note: When you check these batteries,
ensure that you have the polarities correct
on your expanded scale voltmeter.

 Step 2

Check all hardware (linkages, screws, nuts, and bolts)
prior to each day’s flight. Be sure that binding does not
occur and that all parts are properly secured.

 Step 3

Ensure that all surfaces are moving in the proper manner.

 Step 4

Perform a ground range check before each day’s flying
session.

Prior to starting your aircraft, turn off your transmitter, then
turn it back on. Do this each time you start your aircraft.
If any critical switches are on without your knowledge, the
transmitter alarm will warn you at this time.

 Step 7

Check that all trim levers are in the proper location.

 Step 7

All servo pigtails and switch harness plugs should be
secured in the receiver. Make sure that the switch harness
moves freely in both directions.

43

Glossary of Terms

Ailerons: Each side of this airplane has a hinged control
surface (aileron), located on the trailing edge of the
wing. Move the aileron stick on the transmitter left, the
left aileron moves up and the right aileron moves down.
Moving the left aileron up causes more drag and less lift,
causing the left wing to drop down. When the right aileron
moves down, more lift is created, causing the right wing
to rise. This interaction causes the airplane to turn or roll
to the left. Perform the opposite actions, and the airplane
will roll to the right.

Clevis: The clevis connects the wire end of the pushrod
to the control horn of the control surface. Being a small
clip, the clevis has fine threads so that you can adjust the
length of the pushrod.

Control Horn: This arm connects the control surface to
the clevis and pushrod.

Dihedral: The degree of angle (V-shaped bend) at which

the wings intersect the fuselage is called dihedral. More
dihedral gives an airplane more aerodynamic stability.
Some sailplanes and trainer planes with large dihedral
dispense with ailerons and use only the rudder to control
the roll and yaw.

Elevator: The hinged control surface on the back of the
stabilizer that moves to control the airplane’s pitch axis.
Pulling the transmitter’s control stick toward the bottom
of the transmitter moves the elevator upward, and the
airplane begins to climb. Push the control stick forward,
and the airplane begins to dive.

Fuselage: The main body of an airplane.
Hinge: Flexible pieces used to connect the control

surface to the flying surface. All hinges must be glued
properly and securely to prevent the airplane from
crashing. (This has already been done for you on the
Alpha Advanced trainer.)

Horizontal Stabilizer: The horizontal flying surface of
the tail gives the airplane stability while in flight.

Leading Edge: The front of a flying surface.
Main Landing Gear: The wheel and gear assembly

the airplane uses to land. It is attached to the bottom of
the fuselage.

Nose Gear: The part of the landing gear that is attached
to the nose of the fuselage. The nose gear is usually
connected to the rudder servo to help you steer the
airplane on the ground.

Pitch Axis: The horizontal plane on which the airplane’s
nose is raised or lowered. By moving the elevator, you can
raise the airplane’s nose above the pitch axis (climb) or
lower it below the pitch axis (dive).

Pushrod: The rigid mechanism that transfers movement
from the servo to the control surface.

Roll Axis: The horizontal plane on which the airplane’s
wings are raised or lowered. By adjusting the ailerons,
you can drop a wing tip below the roll axis and cause the
airplane to bank or roll.

Rudder: The hinged control surface on the vertical
stabilizer that controls the airplane’s yaw. Moving the
rudder to the left causes the airplane to yaw left; moving
the rudder to the right causes it to yaw right.

Servo: The servo transforms your ground commands into
physical adjustments of the airplane while it’s in the air.

Servo Output Arm: A removable arm or wheel
connecting the servo to the pushrod (also called
servo horn).

Spinner: Term describing the nose cone that covers the
propeller hub.

Threadlock: A liquid that solidifies; used to prevent
screws from loosening due to vibration.

Torque Rods: Inserted into the ailerons, these rigid
wire rods run along the wing’s trailing edge, then bend
downward and connect to the pushrod.

Vertical Stabilizer: The vertical flying surface of the tail
gives the airplane stability while in flight.

Wheel Collar: The round, metal retaining piece that
anchors wheels in place on the wheel axle.

Wing: The lifting surface of an airplane.
Yaw Axis: The vertical plane through which the airplane’s

nose rotates as it yaws to the left or to the right. The
rudder controls the yaw axis.
