H. Activate a circuit (idle-up
(2)
) for 3-D settings and move the collective/throttle stick to exactly half stick.
Adjust the #120-25 pushrod (from the swashplate to the bellmixer) so that the blade reads exactly zero
degrees pitch. Repeat for the remaining blade. Move the stick to full and low positions, reading the pitch at
each. If previous steps were followed accurately, the range above and below zero should be the same. Any
fine tuning can be done in the “swash type” (SWH
) or AFR menus (do not readjust ATV for this). Novice
and intermediate pilots can turn this idle-up function off and set their desired pitch settings within the normal
or idle-up
(1)
pitch curve circuits.
I. Cyclic pitch can now be set. With the fly bar lock and pitch gauge in place, position the rotor head so that one
blade is directly over the tail boom. Move the collective/throttle stick until exactly zero degrees pitch is
shown on the blade. Do not move the stick again. Apply full right and full left Aaileron,@ reading the pitch at
each. The result should be "7 to 7.5 degrees. Adjust SR3
mode (CCPM Swashplate mode) or AFR as needed.
Rotate the rotor head so that the flybar is directly over the tail boom and repeat the process for Aelevator.@
J. Dual rates for aileron, elevator, and/or rudder can be set at 60% if desired. These can be fine tuned at
anytime.
K. Set the throttle settings to approximate those shown in the chart or to the governor settings.
XVI. FINAL INSPECTION
Recheck overall for loose fasteners, interfering components, or incorrect radio installation. Operate all radio
controls making certain that none are reversed and that the throttle can properly close the carburetor.
Be certain the gyro functions in the correct direction.
