CCPM Servo Guidelines

8. Installing and Adjusting Control Components

The goal in the end after all the servos are mounted is to have the swashplate sit level or at 90 degrees to the main shaft and

have the swashplate move equally fore, aft and side to side. The swashplate will also travel up and down as the three servos

work together. This will result if the previous instructions have been followed and the ATV function for the three CCPM servos

has been set very, very accurately to eliminate pitch change when moving the aileron or elevator sticks.

After installing the three cyclic pushrods, the swashplate should sit

level.

Move the collective stick to its maximum position and watch for any

roll (aileron) or pitch (elevator) inputs. If an input is found, the prob-

lem will be one of the following in the table. The table describes the

symptom and the steps to correct them.

Symptom Corrective Solution

metal control ball distance move ball location to match other

servos, or carefully use ATV

angle of horn & servo not 90

use subtrims to set exactly at 90

angle of horn & linage not 90

The Rudder Servo Pushrod changes the pitch of the tail ro-

tor blades to increase or decrease the torque compensation to

rotate the nose of the helicopter about the main shaft.

Use a servo horn in the shape of a cross and trim the 3 of the 4

arms off. The Rudder Servo Pushrod has a preset length from

the factory. Use the 4 Servo screws and 2 servo mounting tabs

to mount the servo with the servo output facing the forward right

side of the helicopter (pictured to the right). At this point, turn

on your radio equipment to center the rudder servo. Attach the

servo horn at 90 degrees aligned with the servo.

Use a servo ball on the outside of the servo arm. Attach the front

end of the rudder control rod to the servo ball.
