Flying the Blade CP+
Having followed the proper 3-in-1 control unit arming procedure, confirmed proper control of the
servos and motors, and found a suitable flying area, your Blade CP+ is ready for flight.
• 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 left-hand (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 CP+ requires minor throttle/collective pitch adjustments to maintain its
altitude in hover. Remember to keep these adjustments as minimal as possible as large adjustments
could result in a loss of control and/or a possible crash.
Note : If you find your model will not lift off the ground with the throttle stick in the highest position,
increasing the throttle trim will add collective pitch. You can also increase the pitch of the blades by
adjusting the Pitch Control Links. See the “Pitch Curve Adjustments” section on page 39 of this manual
for more information.
• 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+ 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 on pages 29–32.
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. Please see page 35 for more information regarding Tail Rotor
Proportional Mix Trimmer Pot adjustment.
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+ is your first single-rotor and/or collective pitch
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.
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.
Note: 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 headspeed (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+ 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.
