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 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 red, then blink, then become solid red again.
Note: It is extremely important that you do not move or sway the
helicopter once the LED begins to blink confirming that the
initialization process and calibration of the gyro has begun. If
you do move the helicopter while the LED is blinking, disconnect
the flight battery from the 5-in-1 unit and repeat the initialization
process.
• When the status LED becomes solid red, the 5-in-1 unit is initialized and ready for
flight. Also, as long as the throttle stick and trim are set to the correct positions
during the initialization process, the ESCs/motors will now be armed. Use caution
as both rotor blades will now spin with throttle stick input.
Note: If the status LED does not become solid red, please review the
following.
• If after blinking red the status LED becomes solid red, 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-middle position. If you
now have control of the motors, proceed to the next step of the checklist.
• If after blinking red 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, then reconnect it. 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,
Horizon Hobby UK at +44 (0) 1279 641 097 or Horizon Technischer Service,
Germany at +49 4121 46199 66.
• 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.
• Advance the throttle stick upward slowly, just until both sets of rotor blades begin
to spin.
DO NOT attempt to fly the helicopter at this time.
Note the direction
that each of the rotor blades spins. When viewed from the top, the upper main
rotor blades should spin counterclockwise and the lower main rotor blades should
spin clockwise. If either set of rotor blades 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 rotor blades is correct, it is
best to confirm that both rotor blades respond properly to rudder control inputs.
With the rotor blades spinning at a low level of power, move the rudder (left-hand)
stick all the way to the right. This should cause the speed of the upper main rotor
blade to increase, and the speed of the lower main rotor blade to decrease.
Next, move the rudder stick all the way to the left. This should cause the speed of
the lower main rotor blade to increase and the speed of the upper main rotor blade
to decrease. If both rotor blades are not responding properly to rudder input, simply
reverse the locations of their motor plugs on the 5-in-1 unit.
After confirming that both rotor blades are rotating in the correct directions, and
are responding properly to rudder inputs, your Blade mCX Tandem Rescue is ready
for flight. However, please be sure to review the following sections of the manual
BEFORE proceeding with the first flight.
Note:
Attempting to fly the helicopter without completely reading the manual may
cause injury to yourself and people in the vicinity, as well as damaging the
helicopter.
