A-38
The 12X features a Balance function that allows the servo
outputs of dual channels to be adjusted throughout the range.
This is useful when two servos are used to drive a single
surface (e.g., two aileron servos used to drive one aileron) and
the linkage geometry of each servo is slightly different (typical
with a tapered aileron). If both servos are mixed in a linear
fashion, binding will occur throughout the control range due
to linkage geometry inaccuracies. The Balance function allows
the servo output of the master servo to be adjusted at 7 points
throughout the range, compensating for any linkage geometry
inaccuracies. Think of Balance as a curve mix that allows the
master channels to be independently adjusted at seven different
points, allowing a perfect bind-free setup throughout the control
stroke.
Note
: Balance is available in the FUNC.LIST only if
Flaperon, Delta or 4-Aileron is selected in the Wing Type
or if any of the dual functions (e.g., dual elevator, dual
rudder, etc.) is activated in Wing Type.
33: Balance
1. Highlight and select Balance in the FUNC.LIST to obtain the
Balance display.
2. Note that the Balance screen will display the functions
that are programmed in the Wing Type. If Flaperon only is
programmed, only one aileron column will appear in the
balance screen. If 4-Ailerons is selected, then two columns
will appear in the balance screen. This also applies to the
dual elevator and rudder functions.
To Program the Balance Function
3. Using the roller, highlight the desired position and press
the roller to access the value. Rotate the roller to change
the output position that is selected. The range is +100 to
-100. Repeat this for all positions until no binding occurs
throughout control travel. Point P-N adjusts that channel’s
neutral point, points P-1 and P-2 adjust that channel’s 50%
travel adjust point, points P-R, P-L, P-U and P-D adjust
that channel’s 100% travel adjust point, and points P<R,
P>L, P<U and P>L adjust that channel’s 150% travel adjust
point.
