•  Once you have the Blade mCX S300 properly trimmed and maintaining a stable 

low-level hover, practice using the rudder, elevator and aileron controls to get a 

feel for how the helicopter responds to control inputs. Remember to keep the 

control inputs as minimal as possible to prevent over-controlling the helicopter, 

especially when in hover.

After becoming comfortable with hovering the Blade mCX S300 at low-levels of 

altitude just a few inches off the ground, you can transition to hovering and flying 

the helicopter at higher altitudes of approximately three to four feet. At these higher 

altitudes you will be able to get a feel for the flight characteristics of the Blade mCX 

S300 when it is flying out of “ground effect.”

•  If at any time during flight you feel like the helicopter is drifting out of control, 

simply release all of the controls except for throttle. You will need to use the 

throttle to maintain altitude, but due to the inherent stability of the coaxial, counter-

rotating blade design, the Blade mCX S300 will simply return to a stable hover on 

its own if space allows.

•  Don’t be afraid to set the helicopter down on the ground quickly by lowering the 

throttle when approaching walls or other obstacles to help prevent main rotor 

blade strikes.

•  IN THE UNFORTUNATE EVENT OF A CRASH OR ROTOR BLADE STRIKE, 

NO MATTER HOW MINOR OR MAJOR, YOU MUST LOWER THE THROTTLE 

STICK TO THE LOWEST POSSIBLE POSITION AS QUICKLY AS POSSIBLE TO 

PREVENT DAMAGE TO THE ESCS OF THE 5-IN-1 UNIT. YOU MUST ALSO 

BE SURE THAT THE THROTTLE TRIM IS SET TO THE MIDDLE POSITION OR 

TO A POSITION THAT IS LOWER THAN THE MIDDLE.

Failure to lower the throttle stick to the lowest possible position in the event 

of a crash could result in damage to the ESCs in the 5-in-1 unit, which may 

require replacement of the 5-in-1 unit.

    Note: Crash damage is not covered under the warranty.

•  Once you have gained experience and confidence in hovering the Blade mCX 

S300, you can attempt more advanced maneuvers including:

 

Forward Flight   

 

Skidding Takeoffs

 

Backward Flight   

 

Skidding Landings

 

Pirouettes 

 

 

Spot Landings

Transmitter and Receiver Binding

Binding is the process of programming the receiver to recognize the GUID (Globally 

Unique Identifier) code of a single specific transmitter. If you ever find it is necessary 

to replace the transmitter or the receiver/5-in-1 unit for your model, it will be 

necessary for you to ‘bind’ the new transmitter or receiver/5-in-1 to your existing 

transmitter or receiver/5-in-1 for proper operation.

The following steps outline the binding process:

• Make sure the flight battery is disconnected from the 5-in-1 unit and the transmitter 

is turned off.

• Plug the flight battery into the 5-in-1 unit. After 5 seconds the LED on the 5-in1 unit 

will begin flashing.

• PUSH directly down on the left-hand stick while switching the transmitter on (you 

will feel a ‘click’ when you push in on the end of the stick).

• If you entered bind mode correctly, you will hear a series of beeps from the 

transmitter and see the LED on the transmitter blink.

• You will see a solid LED approximately 5-10 seconds later on the receiver/5-in-1. 

You should now be bound to the transmitter, and have full control and function.

If you encounter any problems, repeat the binding process again or call the Horizon 

Support Team at 1-877-504-0233.
