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
mCX 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 mCX 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 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 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 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
Flying the Blade mCX
Having followed the proper 5-in-1 control unit initialization and arming
procedures, confirmed proper control of the servos and motors, and found
a suitable flying area, your Blade mCX is ready for flight.
Note: In addition to reviewing the flight maneuvers outlined below,
we recommend that you watch the Instructional Video located on the
product page for the Blade mCX on www.e-fliterc.com to see many
of these maneuvers and adjustments performed by the helicopter
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 mCX 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 mCX
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 settings. Additional
details regarding the location and function of the trim buttons can be
found in the “Understanding the Primary Flight Controls” section of this
manual.
If the nose of the helicopter is drifting to the left or right, you will need to
adjust the rudder trim.
