Installing the Flight Battery ABC - RC

Installing the Flight Battery
Locate the battery compartment on the bottom
of the aircraft.
1. Turn the latch (A) and remove battery
door (B).
2. Install the flight battery (C) in the forwardmost portion of the battery compartment
using hook and loop strips.
– Do Not connect the wires at this time –
3. After connecting the battery, replace the
door on the battery comparment and turn
the latch.
Lower throttle and throttle trim (Mode 2 shown)
To achieve the lowest throttle
trim setting, hold down the
throttle trim button until the
tones stop.
Once arming of the ESC is
complete, return the throttle
trim to neutral by holding
down the top button until
the neutral (3 beep tone)
Connect the Flight battery to the aircraft
Immobilize for 5 seconds
Arming the Electronic Speed
Control (ESC)
Arming the ESC is required every time you
perform a motor test or are ready to fly. To Arm
the ESC, follow the steps below:
1. Lower the throttle stick and throttle trim to
their lowest settings and power on your
2. Connect the flight battery to the aircraft
3. Once the battery is connected, the aircraft
must be immobile for 5 seconds.
CAUTION: Always keep hands away
from the propeller. When armed, the motor
will turn the propeller in response to any
throttle movement.
CAUTION: Always disconnect the LiPo flight battery from the aircraft receiver
when not flying to avoid over-discharging
the battery. Batteries discharged to a voltage lower than the lowest approved voltage
may become damaged, resulting in loss of
performance and potential fire when batteries are charged.
LVC (Low Voltage Cutoff)
LVC is a mechanism built into your ESC to
protect the battery from over-discharge. When
the battery charge is too low, LVC limits power
supplied to the motor. The aircraft will begin to
slow and you will hear the motors pulse.
Battery Precautions for Flight
• Keep the aircraft close until you get familiar
with flight time.
• Do not fly to LVC (motors pulsing) repeatedly.
This may result in battery damage.
• Always disconnect and remove the flight
battery from the receiver when finished

Tail Control Surface
Control Surface Test
The purpose of performing the tail control test is
to confirm that all of the control surfaces move
correctly according to your stick movements.
Mode 2
Mode 1
1. Power on the transmitter.
2. Install a fully charged flight battery and allow
the aircraft’s ESC to initialize.
Every time the aircraft is turned on,
immobilize the aircraft for 5 seconds.
Test the Elevator
• Test your Elevator control by moving your
elevator stick down and up. Make sure that
the elevator responds according to
the illustrations.
Test the Rudder
• Test your rudder control by moving your
rudder stick left and right. Make sure that the
rudder responds according to the
When testing the Rudder, Virtual Instructor
will cause the Elevator to move as well.
Control Surface Centering
Before the first flights, or in the event of an
accident, make sure the control surfaces
(Rudder and Elevator) are centered (aligned)
with the rest of the surface. If the control
surfaces are not centered, centering can be
achieved by following the steps below:
Centered Rudder
Centered Elevator
1. Ensure all trims are neutral. Push the throttle
stick all the way up to neutralize the elevator
to throttle mix.
2. Large centering adjustments can be made by
lengthening or shortening the clevis on the
control rod (see “Attaching the Clevis to the
Control Horn” step 2).
3. Small centering adjustments can be made by
pushing the transmitter’s trim buttons.
Tip! Use of transmitter trim may not correctly
center the aircraft control surfaces due to
the mechanical limits of linear servos.

Reminder! When you fully lower the throttle, the elevator will move up.
Reminder! Before making adjustments, make sure that your trims are neutral.
Installing the Wing
1. Insert the carbon tube (A) into the hole in the
left wing, then slide the right wing onto the
carbon tube. Tabs on the left and right wings
should align once the wings are properly
2. Secure the wing assembly by installing the
Top Wing Plate (B) with the included brackets
and screws on the top and bottom side of the
wing assembly.
3. Install the wing fins (C) on the right and left
wing tips by opening the back side of the
wing fin and sliding it into the slot on the
top of the wing. Secure the fins using the
included 8 pieces of tape (D).
Wing skids (E) help prevent damage to
propellers and wings while learning to fly.
4. Connect the motor wire connectors from the
wing to the correct ESC connectors in the
fuselage of the aircraft.
5. Attach the wing assembly by aligning the
front tab with the fuselage, then aligning the
rear magnets.
Make sure all the wires are inside the
fuselage. Stray wires could prevent the
wing from seating properly.
6. Insert the pin (F) flat side up, onto the wing
plate. Lock the pin into place with 2 screws.
Switch on your transmitter and
attach the flight battery. Arm the
ESC as described in the Arming the ESC
section above, then test the throttle to
confirm that the motors have been correctly
connected to the ESC.
CAUTION: Always keep hands away
from the propeller. When armed, the motor
will turn the propeller in response to any
throttle movement.
Customize your aircraft by appling selfadhesive number decals on top of the right
wing and on both sides of the vertical fin.
Instruction Manual
Choose a Flying Field
In order to have the most success and to protect
your property and aircraft, it is very important
to select a place to fly that is very open. Consult
local laws and ordinances before choosing a
location to fly your aircraft.
Fly in this area
(upwind of pilot)
The site should:
• Have a minimum of 600 feet (183m) of clear
space in all directions.
• Stay clear of pedestrians.
• Stay free of trees, buildings, cars, power lines
or anything that could entangle your aircraft or
interfere with your line of sight.

Stand here
Remember, your aircraft can reach speeds
of up to 25–30 mph (40–48 km/h), so it can
cover ground quickly.
Plan on flying in an area that gives you more
space than you think you need, especially with
first flights.
Range Test
Before you start flying, we suggest you make
sure the aircraft responds to your transmitter.
You will need two people to do the range test—
one to hold the transmitter and one to hold the
1. Power on the transmitter for 5 seconds
or more.
2. With the throttle stick and trim low, plug in
the aircraft battery and keep the aircraft immobile for 5 seconds.
3. One person holds the aircraft while in a
crouched position from the tail of the aircraft
while the other person walks 100 paces
away with the transmitter on.
4. Move the transmitter tail controls and throttle
to ensure they operate smoothly at
100 paces.
CAUTION: While holding the aircraft during the
Range Test, always keep body parts and loose
items away from the propeller. Failure to do so
could cause personal injury.
If your aircraft does not range test correctly, do
not attempt to fly it. Refer to the contact table
at the end of the this manual to contact Horizon
product support.
In good visibility conditions, we recommend
flying your aircraft no more than 400 meters
(approximately 1310 feet) from you. This will
help to prevent loss of orientation as well keep
your aircraft in control range of your radio
