After the three control linkages have been attached to the swashplate, it will be necessary to check the swashplate to ensure that it is level.
To do this, turn on the radio system and place the collective stick in the center position as before. Next, check to make sure that all trim
levers and knobs are also in their center position.
Check to insure that the servo arms are parallel to the servos as adjusted in the previous step. If the servos are not parallel, please refer
to the Sub-Trim section on page 26 and re-adjust as necessary. Once it’s determined that the servo arms are parallel to the servos as
required, it will now be necessary to check the swashplate to insure that it is also level or neutral in this position.
It is suggested that the swashplate first be checked from the rear of the model to insure that it’s level from left to right. If the swashplate
is not level as compared to the frame of the model, adjust either the left or right servo control rod as needed. To determine which rod needs
adjustment, it may be helpful to view the swashplate from the left and right side view of the model to determine which side is high or low.
Once this left-to-right adjustment is completed, it will now be necessary to check the fore/aft position of the swashplate to insure that it is
also level on this axis. If the swashplate is not level in the fore/aft axis, it is suggested that the adjustment be made to the front servo control
linkage as needed. If you are unsure as to which linkage needs adjustment or are having difficulty obtaining the correct adjustment, please
check the length of each control rod to insure that it is adjusted to the correct length as outlined in Step 3-5.
Note: If care was taken in the linkage attachment in Step 3-5, little or no adjustment should be required in this step. Only minor
adjustments should be made to the lengths of the control linkages at this time. Any major adjustments indicates either incorrect
linkage lengths or incorrect servo arm positioning. If the control linkage lengths are altered from the recommended lengths more
that one or two turns, this will have a great effect on the range and settings of the collective pitch in later steps.
