PITCH-TO-AILERON MIXING ADJUSTMENT WITH TRAVEL ADJUST
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 7-6.
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 would 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, then the travel value of the right servo should be increased slightly and
retest. In most cases, it will require only the adjustment of the left or right servo to correct this situation.
For information on the travel adjustment function, please refer to page 49 or your radio instruction manual for details. Once this
condition has been corrected, repeat this procedure for the center to low collective pitch position and adjust as needed.
View is shown from the rear of the
model. Notice how in this example the
swashplate has tilted to the right as the
collective has moved from center to full
high pitch position.
