Step 1

Charging the Aircraft Battery

Your T-28D comes with a DC balancing charger and 3S
Li-Po battery. You must charge the included Li-Po battery
pack with a Li-Po specific charger only (such as the
included charger). Never leave the battery and charger
unattended during the charge process. Failure to follow
the instructions properly could result in a fire. When
charging, make certain the battery is on a heat-resistant
surface. It is recommended to charge the battery pack
while you are assembling the aircraft. The flight battery
will be required to confirm proper aircraft operation in
future steps.

DC Li-Po Balancing Charger Features

• Charges 2- to 3-cell lithium polymer battery packs

• Variable charge rates from 300mAh–2A

• Automatically detects incorrect cell count selection

• Simple single push-button operation

• LED charge status indicator

• LED cell balance indicator

• Audible beeper indicates power and charge status

• 12V accessory outlet input cord

Specifications

• Input power: 12V DC, 3A

• Charges 2- to 3-cell Li-Po packs with minimum

capacity of 300mAh

• Variable charge rates from 300mAh to 2 amps

3S 11.1V 1800mAh Li-Po Battery Pack

The ParkZone 3S Li-Po battery pack features a
balancing lead that allows you to safely charge your
battery pack when used with the included ParkZone Li-Po
balancing charger.

To Complete the Charging Process

1. Attach the input cord of the charger to the

appropriate power supply (12V accessory outlet),

or use the HBZ6513 (Alligator Clip input adapter for
12V) and attach to 12V DC power supply. Once
your charger has been correctly powered up, there
will be an approximate 3-second delay and then you
will hear an audible “beep” and the green (ready) LED
will flash.

2. Refer to the char t below to select the appropriate
charge rates:

300—400mAh 300mAh
500—1000mAh 500mAh

1000—1500mAh 1A
1500—2000mAh 1.5A
2000mAh + 2.0A

BATTERY CAPACITY

MAX. CHARGE RATE

Warning: Selecting a charge rate higher than 1x
battery capacity may cause a fire.

3. Select the proper number of cells that you will be
charging, either 2 or 3 cells.

4. Locate the safety charge lead on the battery pack.
The charge lead of a 3-cell Li-Po battery will plug
into the larger 4-pin port on the bottom right of the
charger. A 2-cell pack will need to plug into the 3-pin

port on the bottom left of the charger. Once the

battery is properly plugged into the correct port,
it will beep 3 times if it is a 3-cell, and twice if it is

a 2-cell pack. Once this is done, you are ready to

proceed to charge the battery pack.

5. Push the start button to begin the charging process.

Once this is done, the charger will make an audible

beep that matches the cell count, and then the red
(charge) LED will begin to flash. Do not adjust the
current once the charger has begun to charge.

Note: At times, the green LED may also flash during
the charging process, indicating that the charger is
balancing one or more of the cells at the same time it
is charging the battery pack. When this is occurring,
the red and green LEDs will both be flashing. It will not
always be necessary for the cells to be balanced.

6. When the battery pack is fully charged, you will hear
an audible beep for about 3 seconds, and the green
LED will be solid. Always unplug the battery from the
charger immediately upon completion. Failure to do
so could cause a fire.

Warning: Failure to use the proper charger for a
Li-Po battery can result in serious damage, and if left
charging long enough, will cause a fire. ALWAYS use
caution when charging Li-Po batteries.

Transmitter and Receiver Binding

Binding is the process of programming the receiver of
the control unit to recognize the GUID (Globally Unique
Identifier) code of a single specific transmitter. It will be
necessary for you to ‘bind’ your chosen Spektrum DSM2
technology equipped transmitter to the receiver for
proper operation.

The transmitter you select must be a DSM2 full
range (high power) Tx. The following is a list of

some of the Spektrum DSM2 equipped full range
transmitters and modules that will bind to the receiver of
the T-28D Trojan:

Spektrum DX5e JR X9303 2.4

Spektrum DX6i JR 12X 2.4

Spektrum DX7/DX7SE EFLH1056

All SPM Module systems

The following steps outline the binding process:

• Confirm the process of entering the bind mode for

your chosen transmitter by reviewing the instruction
manual included with the transmitter.

• Make sure the flight battery is disconnected from the

receiver unit and the transmitter is turned off.

• Plug the bind plug into the Batt/Bind port on the

AR500 receiver.

• Plug the flight battery into the battery lead of the

ESC. The LED on the receiver unit will begin flashing.

Note: NEVER plug the balance lead of the battery
directly into the receiver. This will cause damage to the
receiver and battery.

• After verifying the LED is flashing on the receiver,

follow the steps that allow your chosen transmitter to
enter bind mode.

• If you entered bind mode correctly, you will see a
solid LED approximately 5–10 seconds later on the

receiver. You should now be bound to the transmitter,
and have full control and function.

• Remove and store bind plug in a safe place.

If you encounter any problems, repeat the binding
process again, see the troubleshooting guide or call the
Horizon Support Team at 1-877-504-0233.

Transmitter Control Identification

Note: Each time before you fly you should ALWAYS turn

the transmitter on before connecting the flight battery
to the receiver unit. After each flight, be sure that you
always disconnect the flight battery from the receiver
unit before powering the transmitter of f.

Additional Binding Information

Prior to each flight, you should ensure that you power on
your transmitter and wait about five seconds before you
plug the flight battery into the receiver. Doing this allows
time for the transmitter to scan and secure two open
frequencies. If the flight battery is plugged in too quickly
and the link is missed, it may not allow the receiver to
connect to the transmitter. If this occurs, simply leave
the transmitter on and then disconnect and reconnect the
flight battery.

Note: If using a Futaba transmitter with a module, it
may be necessary to reverse the throttle channel.

Step 3 Step 4

Attaching the Wing

In order to attach the wing of your T-28D, please follow
these simple instructions:

1. Locate the included wing-securing screw.

2. Turn over the fuselage so you are looking at the
bottom. Do the same with the wing.

3. Connect the aileron leads to the pre-installed
Y-harness, noting proper orientation. Route the
Y-harness lead through the access hole in the bottom
of the fuselage.

4. Carefully align the two locator pins on the front of
the wing into the two small holes in the front of the
fuselage.

5. Slide the aileron leads inside the fuselage so that
they will not become pinched in between the wing
and the fuselage when securing the wing.

6. Slide the bottom of the leading edge of the wing into
the fuselage as shown, making certain it is perfectly
centered. This must be done correctly in order to

allow the screw to thread into the fuselage. Once you

are certain the wing is centered, tighten the screw to
secure the wing.

7. The wing is correctly installed when no gap exists
between the wing and fillet.

8. Gently pull up on the rear of the canopy hatch to
remove and set aside.

9. Plug the Y-harness lead into one of the AIL ports of
the Spektrum AR500 receiver.

Installing the Landing Gear

1. Install the main landing gear by inserting it into the
locator hole in the wing. Swivel the landing gear
toward the retaining clips and gently snap into place.

2. Insert the nose gear into the steering assembly
on the underside of the cowl with the flat spot
facing forward.

3. Align the retaining screw with the flat spot on the
cowl. The retaining screw should be visible through
the front of the cowl.

4. Using a Phillips screwdriver, tighten the retaining
screw. The retaining screw should be accessible
through the front of the cowl, however, you may
choose to remove the cowl for easier access.

5. Reposition the T-28D so that it is resting on the
landing gear.
