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 +10. The maximum pitch range that you
will require will be 15°. If you are a 3D pilot flying the Venture, then your
maximum negative pitch will be -10, and your maximum positive pitch
will be +10 (+13 for autorotations). The maximum pitch range that you
will require will be 23°.
The maximum pitch range mentioned above must be established
through the use of the pitch travel value in the CCPM function. 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 3-7 and 3-8. Please
refer to the CCPM activation section, pages 20-22, 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 various
flight conditions. Since throttle curves can vary greatly due to engine
and muffler combinations, it will be necessary to fine tune and adjust
these values during test flights to achieve a constant main rotor rpm.
It will also be necessary to set the correct idle speed of the engine when
the Throttle Hold function is activated. This idle value is located within the
Throttle Hold function. This will allow the engine to remain at idle when
practicing autorotations.
