It will now be necessary to establish the maximum pitch value
required for your application prior to adjustment. For example, if you are
a beginning pilot, then your maximum negative pitch will be -5, and your
maximum positive pitch will be +15. The maximum pitch range that you
will require will be +15.
The maximum pitch range mentioned above must be established
through the use of the pitch travel value in the CCPM function. As
mentioned previously, do not try to establish the maximum pitch curve
values through adjustment of the travel adjustment function, as this will
alter the pitch-to-aileron and pitch-to-elevator travel values established in
Steps 5-5 and 5-6. Please refer to the CCPM activation section
(pages 35–37) for information on how to access the CCPM function.
Once the CCPM function has been activated, set the maximum
positive pitch settings as mentioned above. Since the CCPM function
does not allow for independent travel settings for positive and negative
pitch, it will be necessary to establish the maximum positive pitch, since
this is generally the largest degree of pitch in the pitch range. Once the
maximum positive pitch range is set, the maximum negative pitch range
can be reduced as needed through the pitch curve function.
Set the main rotor pitch gauge to the desired maximum pitch setting,
then increase or decrease the CCPM pitch travel (labeled Pitch or Ch6) as
needed until this pitch setting is achieved.
Once this procedure has been completed, the positive and negative
pitch settings for each flight mode can be adjusted through the radio’s
pitch curve function. Please refer to your radio’s instruction manual for
more information.
B. THROTTLE CURVE SETTINGS
Below are several examples of possible throttle curves during vari-
ous flight conditions. Since throttle curves can vary, it will be neces-
sary to fine tune and adjust these values during test flights to achieve
a constant main rotor rpm.
