Flying The Mqx; First Flight - Horizon Hobby BLADE MQX Mode D'emploi

4-in-1 Control Unit Function
The unique Control Unit installed in your mQX is a lightweight combination of main motor electronic speed controls
(ESCs), mixers, gyros and a DSM2 receiver. The 4-in-1 unit is also equipped with a blue status indicator LED.
• Before each flight, ALWAYS power on the transmitter before connecting the flight battery to the 4-in-1 unit.
After each flight, disconnect the flight battery from the 4-in-1 unit before powering off the transmitter.
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.
• The 4-in-1 unit will arm the motors when the throttle stick is in the lowest possible position and the throttle
trim is at the middle or a lower than middle position (the middle position is indicated by a longer than usual
beep/tone). If this is the first test flight, or a test flight following repairs, also center the rudder, aileron and
elevator trims.
• With the transmitter turned on and the transmitter LED glowing solid RED, it is safe to connect the flight bat-
tery to the 4-in-1 unit.
• Connect the flight battery to the 4-in-1 unit.
• After the flight battery is connected, the 4-in-1 unit status LED should glow solid BLUE within a few seconds.
DO NOT move, sway or pretend to fly the Quad-Copter after connecting the flight battery. This movement can
stop unit initialization and gyroscope calibration. If the Quad-Copter is moved before the 4-in-1 unit status
LED glows solid BLUE, disconnect then connect the flight battery to the 4-in-1 unit.
• When the 4-in-1 unit status LED glows solid BLUE, the control unit is initialized and ready for flight.
• As long as you set the throttle stick and trim to the correct positions during the initialization process, the ESC
or motors will be armed. Use caution because after arming, propellers will turn at throttle stick input.

Flying the mQX

• After confirming the rotor blades rotate in the correct direction, test the motor response controls.
• Adjust the throttle to a low level of power where the quad-copter begins to get "light" on its landing skids.
• Now move the rudder stick a small amount to the right. The nose of the quad-copter should start to rotate to
the right (clockwise).
• Move the rudder stick a small amount to the left. The nose of the quad-copter should start to rotate to the left
(counter-clockwise). If the nose moves to the right, please refer to the Troubleshooting Guide.
• Move the elevator control stick forward. The two REAR landing skids should lift from the floor
• Move the elevator control stick backward. The two FRONT landing skids should lift from the floor.
• Move the aileron stick right. The two LEFT landing skids should lift from the floor.
• Move the aileron stick left. The two RIGHT landing skids should lift from the floor.
• When rotors turn correctly and respond correctly to controls, your mQX is ready for its first flight!

First Flight

• Increase the throttle until the model is approximately 2 ft. (600mm) off the ground in a low-level hover and
concentrate on balancing the throttle stick's position so that the mQX holds a steady hover altitude. In some
cases, you may need to make a few short "hops" to an altitude of just a few inches until you become familiar
with the control inputs and trim settings required to maintain a steady hover and altitude.
The mQX requires minor throttle adjustments to maintain its altitude in hover. Remember to keep these throttle
adjustments as minimal as possible as large adjustments could result in a loss of control and/or a possible crash.
• While attempting to establish a low-level hover, you can also check to see if any trim adjustments are
required to help keep the mQX from constantly drifting in various directions. If you find that it constantly drifts
without any directional control input, land the model before making any adjustments to the trim settings. Ad-
ditional details regarding the location and function of the trim buttons are in the "Understanding the Primary
Flight Controls" section of this manual.
- If the nose of the mQX rotates to the left or right, adjust the rudder trim.
- If the mQX continually drifts forward or backward, adjust the elevator trim.
- If the mQX continually drifts to the left or right, adjust the aileron trim.
