• 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 CP Pro 2 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 locations and functions of the trim lever 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. You can also
adjust the tail rotor proportional mix if you experience any difficulties in trimming nose drift with the rudder
trim lever only . See the “Tail Rotor Proportional Mix Trimmer Pot Adjustment” section of this manual for more
information .
• 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 CP Pro 2 is your first single-rotor and/or collective pitch helicopter model,
it may be best to have an experienced helicopter pilot trim the model for you before making your first flight .
Note:
The throttle trim can be used to adjust the throttle and collective pitch values for a given throttle stick
position . For example, raising the throttle trim will allow the model to hover at a lower throttle stick position .
Also, if you find that your model “jumps” either upward or downward when in a hover, with little to no control
input, you may need to adjust the overall pitch curve so that it is better matched to the throttle curve for
smoother response . By decreasing the length of both adjustable pitch control links by approximately one-half to
one full turn, it will lower the pitch of the rotor blades for a given throttle/collective stick position . This will allow
the model to hover at a higher head speed (main rotor blade rpm), offering a smoother, more stable feel and a
pitch curve that is better matched to the throttle curve .
• Once you have the Blade CP Pro 2 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 CP Pro 2 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 helicopter when it
is flying out of “ground effect .”
• Don’t be afraid to set the helicopter down on the ground quickly by lowering the throttle when approaching
obstacles to help prevent main rotor blade strikes . Also, the optional training gear set will help to further
prevent damage to the helicopter in the event that you must make an abrupt landing to avoid walls or other
obstacles when it is installed .
If at any time during the flight you feel like the helicopter is drifting out of control, it is best to return all controls
to neutral and to lower the throttle stick completely or activate Throttle Hold . This will help reduce the amount of
damage that may be caused in the event of a crash .
• If at any time during flight you feel like the helicopter is drifting out of control, it is best to return all controls to
neutral and to lower the throttle stick and trim completely or to activate Throttle Hold . This will help to reduce
the amount of damage that may be caused in the event of a crash .
•
IN THE UNFORTUNATE EVENT OF A CRASH OR ROTOR BLADE STRIKE,
NO MATTER HOW MINOR OR MAJOR, YOU MUST LOWER BOTH THE
THROTTLE (LEFT-HAND) STICK AND THROTTLE TRIM TO THEIR LOWEST
POSSIBLE POSITIONS (WHEN IN THE NORMAL FLIGHT MODE) AS
QUICKLY AS POSSIBLE TO PREVENT DAMAGE TO THE ESCS OF THE
2-IN-1 UNIT. YOU CAN ALSO ACTIVATE THROTTLE HOLD IN ANY FLIGHT
MODE, REGARDLESS OF THROTTLE STICK POSITION.
Failure to lower both the throttle stick and throttle trim to their lowest possible positions (in the normal Flight
Mode only) or to activate Throttle Hold (in any Flight Mode) in the event of a crash could result in damage to the
ESCs in the 2-in-1 unit, which may require replacement of the 2-in-1 unit .
While the 2-in-1 control unit main motor and tail motor ESCs are readily capable of handling all in-flight power
loads, and even brief momentary bursts beyond these typical loads, they can be damaged if excessive amounts
of current are pulled through them for an extended period of time . This period of time may vary depending
on many conditions, so it is best to keep any momentary overloads as short as possible in order to prevent
damage to the 2-in-1 ESCs .
Note: Crash damage is not covered under warranty .
• It is extremely important when hovering and flying the Blade CP Pro 2 to be aware of the power level of the LiPo
battery pack . If at any time the helicopter begins to require more throttle than typical to maintain hover or flight,
or has lost the ability to maintain hover or flight due to significant loss of power, you must land the helicopter
and power the motors down IMMEDIATELY to prevent over-discharge of the LiPo battery pack.
If you continue to run the motors after noticing a loss in power it is possible to discharge the LiPo battery pack
too far, causing permanent damage to the pack . Over-discharge of the LiPo battery pack can result in shortened
flight times, loss of power output or failure of the pack entirely
