Flying the Blade™ CX
Having followed the proper 4-in-1 control unit arming procedure, confirmed proper control of the
servos and motors, and found a suitable flying area, your Blade CX is ready for flight.
In addition to reviewing the flight maneuvers outlined below, we recommend that you watch the included
Instructional Video CD to see many of these maneuvers and adjustments performed by the Blade CX and pilot.
• Slowly raise the throttle stick, increasing the speed of the main rotor blades until the model begins to lift off.
Do not raise the throttle stick too quickly as the model could climb too fast causing you to lose control or make
contact with objects above.
• Lift the model off the ground just a few inches and concentrate on balancing the throttle stick position so that
the model holds a steady hover altitude. In some cases it may be best 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. As you will find, the Blade™ CX 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 Blade CX from constantly drifting in various directions. If you find the helicopter constantly
drifts without any directional control input, it will be best to land the model before making any adjustments
to the trim levers. Additional details regarding the location and function of the trim levers can be found in the
“Before the First Flight” section of this manual (page 21-23).
If the nose of the helicopter is drifting to the left or right, you will need to adjust the rudder trim. You can also
adjust the Main Motor Proportional Mix if you experience any difficulties in trimming nose drift with the rudder
trim lever only. Please see the “Main Motor Proportional Trimmer Pot Description and Adjustment” section of this
manual for more details (page 26).
If the helicopter is drifting forward or backward, you will need to adjust the elevator trim.
If the helicopter is drifting to the left or right, you will need to adjust the aileron trim.
Continue to make trim adjustments until the helicopter can hover at a low altitude with very little drifting and
directional control input. If the Blade CX is your first helicopter model, it may be best to have the help of an
experienced helicopter pilot to trim the model for you before making your first flight.
• Once you have the Blade CX 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. Additional details regarding the control functions can be found in the “Before the First Flight” section of
this manual (page 21-23).
• After becoming comfortable with hovering the Blade CX 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 CX 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 blades, the Blade CX will simply return to a stable hover on its own if space allows.
