information. Some customers find it easier to lay the helicopter on
its side while connecting the flight battery, then leaving it on its side
during the initialization process.
• The throttle stick MUST be set in the lowest possible position, and the
throttle trim must be set to the middle or a lower than middle position (the
middle position is indicated by a longer than usual beep/tone), in order
for the 5-in-1 unit to arm.
• The rudder stick MUST be left NEUTRAL (CENTER STICK), and the rudder
trim must be set to the middle position (the middle position is indicated
by a longer than usual beep/tone), in order for the 5-in-1 unit to arm
properly
If this is the first test flight, or a test flight following repairs, you should also center
the rudder, aileron and elevator trims.

• After confirming that the transmitter has been turned on and that the LED is
glowing solid red, it is now safe to connect the flight battery to the 5-in-1 unit.
• With battery power applied to the 5-in-1 unit, the status indicator LED
should glow solid blue, then blink, then become solid blue again.
Note: It is extremely important that you do not move, sway, or pretend to
fly the helicopter once the flight battery is connected because the
initialization process and calibration of the gyro has begun. If you
do move the helicopter before the LED is solid BLUE, disconnect
the flight battery from the 5-in-1 unit and repeat the initialization
process.
• When the status LED becomes solid blue, the 5-in-1 unit is initialized and ready
for flight. Also, as long as you had the throttle stick and trim set to the correct
positions during the initialization process, the ESC/motors will now be armed.
Use caution as both main rotor and tail rotor blades will now spin with throttle
stick input.
Note: If the status LED does not become solid blue, please review the
following.
• If after the status LED becomes solid BLUE, but you have no control of the motors,
you have a positive Radio Frequency (RF) link between the transmitter and receiver,
but the throttle stick and throttle trim may not be set to the correct positions.
Check to be sure that the throttle stick is in the lowest possible position, and that
the throttle trim is set to the middle or a lower than the middle position. If you now
have control of the motors, proceed to the next step of the checklist.
• If the status LED turns off completely, you do not have a positive RF link between
the transmitter and receiver. Check to be sure that the transmitter has been
powered on and that the LED indicator on the transmitter is glowing solid red.
If the transmitter is powered on and functioning properly, disconnect the flight
battery from the 5-in-1 unit, move the transmitter at least 2 feet away from the
aircraft, then reconnect the flight battery. Now the 5-in-1 unit should initialize and
arm properly.
If your 5-in-1 unit will not initialize and arm after following the guidelines as listed
above, call the Horizon Support Team at 1-877-504-0233.
• Once you have placed the helicopter in a safe area, free of obstructions,
and are clear of the rotor blades, you can safely begin to power up the
model to check for proper operation of the motors.
Note: Attempting to fly the helicopter without completely reading the
manual may cause injury to yourself and people in the vicinity, as
well as damage to the helicopter.
Once you have placed the helicopter in a safe area, free of obstructions, and are
clear of the main and tail rotor blades, you can safely begin to power up the model
to check for proper operation of the motors.
• Advance the throttle stick upward slowly, just until both main and tail rotor blades
begin to spin. DO NOT attempt the fly the helicopter at this time. Note the
direction that the main and tail rotor spins. When viewed from the top, the main
rotor blades should spin clockwise. When viewed from the right-hand side of the
helicopter, the tail rotor should spin counter clockwise. If either one of the rotors is
operating in the wrong direction, disconnect the battery and reverse the polarity of
the corresponding motor’s input power leads.
• After confirming that the direction of rotation for both main and tail rotors is
correct, it is best to confirm that the tail rotor respond properly to rudder
control inputs.
