ADVANCED SETUP: PITCH-TO-AILERON MIXING ADJUSTMENT
WITH TRAVEL ADJUST (OPTIONAL)
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 3-8.
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, 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 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.
Beginners can proceed to step 3-9.
