Three servos are mounted on the front and rear servo brackets. They work together to tilt the swashplate producing the
collective pitch, roll cyclic pitch (aileron control) and the fore-aft cyclic pitch (elevator control). The servo horns pro-
vided in the radio will not be long enough to achieve the full collective range, the control ball is required to be mounted
at a distance of 25-26mm from the center of the servo. It is recommended to use Century’s optional metal servo arms
as follows:
(CN2189 - Futaba, CN2185 - JR/Airt, CN2181 - Hitec) for all standard plastic output shaft servos.
(CN2279FM - Futaba, CN2279JM - JR, CN2279HM - Hitec) for all metal gear output shaft servos.
Attach one steel ball with one 2mm nut to the top-side of the rear servo horn and to the top-side of the two horns for
the front servos using threadlock. With the radio turned on and the trims centered, attach the rear servo horn parallel to
the body of the servo and the CCPM Rear (E) Pushrod. Similarly, attach the front servo horns mounted 90 degrees to
the servo with the CCPM Front (D) Pushrods.
Move the collective stick to its maximum position and watch for any roll (aileron) or pitch (elevator) inputs. If an input is
found, the problem will be one of the following in the table. The table describes the symptom and the steps to correct
them.
Step 37 CCPM Swashplate Linkage
metal control ball distance
move ball location to match other servos, or carefully use ATV
angle of horn & servo not 90
0
use subtrims to set exactly at 90 degrees
angle of horn & linkage not 90
0
use subtrims to set exacly at 90 degrees, noticeable at extremes
swashplate not level
adjust pushrod length to level
