It is very possible that the travel of each servo varies slightly, which can cause the swashplate to be tilted to
the left or right when the collective is moved to the extreme high and low pitch positions. This condition is
generally more common when standard type servos are used. If JR
®
digital servos are used, the adjustment
required is generally very small, if any. These variations in travel can be corrected by altering the travel value
of each servo slightly through the travel adjustment function.
To check the pitch-to-aileron mixing, it will first be necessary to position the collective stick in the center
position as in the previous steps. Next, move the collective stick from the center position to the high pitch
position while viewing the swashplate from the rear of the model as shown in the diagram below. While
moving the swashplate, look for any tendency for the swashplate to roll to the left or right as it reaches the high
pitch position. Repeat this procedure several times to be sure that your observations are correct. If no rolling
tendency is found, it will now be necessary to repeat this procedure from the center collective stick position to
full low pitch. If no rolling tendency is found, proceed to Step 7-9.
In our example, we have shown that the swashplate has been tilted to the right as the collective has been
increased to full pitch. This would indicate that the left servo’s maximum travel is greater than the right servo’s
maximum travel.
In this condition, we suggest that the travel value for the left servo be reduced slightly (5–10%). Repeat
the procedure above if the same condition occurs, but to a lesser degree. The travel value of the right servo
should be increased slightly and retested. In most cases, it will require only the adjustment of the left or right
servo to correct this situation.
View is shown from the rear of the model. Notice how the
swashplate has tilted to the right as the collective has moved
from center to full high pitch position.

Once this condition has been
corrected, repeat this procedure for
the center to low collective pitch
position and adjust as needed.
