Spektrum SPMAR7200BX - Manual (Page 26)

ImpoRTANT: If the tail pirouettes and stops unevenly in both directions, set
the tail gyro to Normal-Rate mode. Test whether the tail will drift in a particular
direction during hover. If it does, adjust the tail link rod length so the tail rotor
blades have the required compensation for pitch. If you adjust the tail link rod
length, you must reset the tail rotor limits (Setup menu point (E)). If you chose
“Transmitter” in the Control Behavior (Parameter menu point (B)), make sure you
are not entering the free spinning range, which can cause inconsistent rotation.
The option “User Defined” allows you to define your own settings using the
optional PC Software.
Press the setup button once to move to Parameter menu point (E).
E. Stick Deadband
Stick deadband is the range around the very center of the stick where the
AR7200BX will not react. Depending on the calibration of the transmitter, the sticks
may not be in the exact same center position each time they return to center. This
can cause unwanted rotation on the axis of stick movement.

Setting
Stick Deadband
Set Too Low
It is difficult to find a stick position where no input is
sent to the AR7200BX. A setting too low can lead to
a helicopter tipping on takeoff or a helicopter that is
difficult to control.
Stick Deadband
Set Too High
You will feel a large range of stick movement where you
have no control. A setting too high can lead to difficult
precision hovering.
