Revolutionary SAFE®(Sensor Assisted Flight Envelope) technology uses an innovative combination of multi-axis sensors
and software that allows model aircraft to know its position relative to the horizon. This spatial awareness is utilized to
create a controlled flight envelope the aircraft can use to maintain a safe region of bank and pitch angles so you can fly
more safely. Far beyond stability, this level of protection offers multiple modes so the pilot can choose to develop his or
her skills with a greater degree of security and flight control that always feels crisp and responsive.
SAFE®technology delivers:
•Flight envelope protection you can enable at the flip of a switch.
•Multiple modes let you adapt SAFE®technology to your skill level instantly.
Best of all, sophisticated SAFE®technology doesn’t require any work to enjoy. Every aircraft with SAFE®installed is ready
to use and optimized to offer the best possible flight experience.

•In stability low angle mode, the controls provide a minimum bank angle.
•In stability high angle mode, the controls provide for a maximum bank angle.
•In agility mode, the system does not self level. Use rates and expo to tune the performance according to your flying style.

To bind or re-bind your quadcopter to your chosen transmitter, please follow the directions below.
CAUTION: When using a Futaba®transmitter with a Spektrum™ DSM2®module, you must reverse the throttle
channel and re-bind. Refer to your Spektrum module manual for binding and failsafe instructions.
Refer to your Futaba transmitter manual for instructions on reversing the throttle channel.
If you encounter problems, obey binding instructions and refer to the troubleshooting guide for other instructions.
If needed, contact the appropriate Horizon Product Support office. For a list of compatible DSM®transmitters,
please visit www.bindnfly.com.
Transmitter and Receiver Binding
Installing the Flight Battery
CAUTION: Always disconnect the Li-Po battery from the quadcopter 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.
CAUTION: Connecting the battery to the ESC with reversed polarity will cause damage to the ESC, the battery
or both. Damage caused by incorrectly connecting the battery is not covered under warranty.
1. Lower the throttle.
2. Power on the transmitter.
3. Center the throttle trim.
4. Attach hook material to the quadcopter frame and loop
material to the battery.
5. Install the flight battery on the quadcopter’s bottom frame.
Secure the flight battery using the battery o-ring. Connect the
battery cable to the ESC, noting correct polarity.
6. Do not move the quadcopter until the receiver initializes.
7. The quadcopter motor will emit initialization tones, indicating
the ESC is armed.
General Binding Procedure
1. Program your transmitter using the Transmitter Setup found in this manual.
2. Insert the bind plug in the BIND port on the receiver (BND/PRG).
3. Connect the flight battery to the ESC. The A3174 receiver will flash, indicating it is in bind mode.
4. Move the throttle stick to the desired failsafe position (low throttle position in normal mode).
5. Power on transmitter while holding the BIND button. The system will connect within a few seconds.
6. Binding is complete when the orange LED on the receiver glows solid.
7. Remove the bind plug from the receiver before you unplug the battery and power off the transmitter. (Store the bind
plug in a convenient location).

Preparing the Mach 25TM Quadcopter for Flight
1. Before each flight, ALWAYS power on the transmitter before connecting the flight battery to the control unit. After each
flight, disconnect the flight battery from the control unit before powering off the transmitter.
NOTICE: Connecting the flight battery before powering on the transmitter can start the binding process. Please see
the Transmitter and Receiver Binding section of this manual for more information.
2. When the ESC beeps, the control unit is initialized and ready for flight.
The control unit will not arm the motors until the throttle stick is in the lowest possible position and the throttle trim is at
the middle or a lower than middle position.
Consult local laws and ordinances before operating FPV equipment. In some areas,
FPV operation may be limited or prohibited. You are responsible for operating this
product in a legal and responsible manner.
1. Power on your radio transmitter, then power on the aircraft. Wait for the initializaion
tones.The 25mW Micro Camera will automatically power on when the battery is
connected to the Mach 25.
2. Power on the headset to make sure the channel is clear.
3. Perform a range test before flying.
NOTICE: You can only enter Channel Changing Mode prior to starting the motors.
4. Use the right and left sticks to select a channel according to Mode 1 or Mode 2.
Normal operation resumes when the throttle is lowered.
NOTICE: If your radio/transmitter uses right stick throttle, use Mode 1 illustration.
If your radio/transmitter uses left stick throttle, use Mode 2 illustration.
NOTICE: The 25mW Micro Camera range on your Quadcopter is less than your
transmitter range. Ensure you have adequate camera range for filming.
Tip: If you are prone to motion sickness, sit in a chair. If you start to suffer from motion
sickness while flying, lower your chin against your chest.
Fly in open areas, away from people, trees, cars, and buildings. The range of the
system can be impacted by any obstructions blocking your signal. It is normal to see
break up in the video going behind trees and other obstacles.
Tip: Adjust the camera angle as you see fit, using the included double-sided foam tape.

Takeo
When you are prepared to fly, start the motors by moving both sticks to the bottom inside corners, then back to center.
Increase the throttle until the model is approximately 2 ft. (600mm) off the ground and check the trim so the model flies
as desired. Once the trim is adjusted, begin flying the model.
Typical flight times for the included battery range from 5–7 minutes.
Low Voltage Cuto (LVC)
LVC decreases the power to the motors when the battery voltage gets low. When the motor power decreases and the
LEDs blink, land the aircraft immediately and recharge the flight battery.
LVC does not prevent the battery from over-discharge during storage.
NOTICE: Repeated flying to LVC will damage the battery.
Landing
To land, slowly decrease the throttle while in a low-level hover. After landing, activate the throttle cut feature to shut off
the motors; disconnect and remove the battery from the aircraft after use to prevent over discharge. During storage,
make sure the battery charge does not fall below 3V per cell.
Flying the Mach 25TM Quadcopter
Installing the Propellers
Caring for the Video Transmitter Antenna
If your video transmitter antenna gets bent or flattened as a consequence
of a hard landing, bend the antenna so the lobes are at a 45° angle to the
bottom plane of the antenna, as shown at the right.
NOTICE: A bent or broken antenna will adversely affect
camera use.

Post-Flight Inspection and Maintenance Checklist
√
Cleaning Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush
or a dry, lint-free cloth.
Motors Replace the motor when the model will not fly steady or veers off when doing a climb out.
Wiring Make sure the wiring does not block moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over-tighten metal
screws in plastic parts. Tighten screws so the parts are mated together, then turn the screw only
1/8th of a turn more. Do not use threadlock on or near plastic parts.
Propellers Make sure there is no damage to the propellers or other parts that move at high speed. Damage to
these parts includes cracks, burrs, chips or scratches. Replace damaged parts before flying.
