Installing Servos
Connect the servo leads to the appropriate ports in the Spektrum Cockpit and
prepare to bind the system to your transmitter.
The Spektrum Cockpit has 4 dual-matched channels available to operate 2 separate
ailerons, rudders, aux 1, flap or any other available channel servos. Use the built-in
servo matching feature to adjust each of the 4 dual-channel servo ports to match
each other. These ports can be matched at the servo center points as well as each
endpoint.
NOTICE: Failure to match ganged servos throughout the range of motion on a
control surface will result in high amperage drawn by the servos, which can lead
to servo failure. Use an inline current meter (such as the HAN172) to adjust for
decreased current draw in the system.
NOTICE: Only use standard, non-amplified Y-harnesses and servo extensions with
Spektrum equipment. Use of amplified Y-harnesses or servo extensions will cause
the servos to operate erratically or not function with Spektrum equipment. Amplified
Y-harnesses were developed to boost the signal for some older PCM systems and
should not be used with Spektrum equipment. When converting existing models
to use Spektrum equipment, make sure all amplified Y-harnesses and/or servo
extensions are replaced with conventional, non-amplified versions.
The JR® PCM Y-Harness with Amplifier (JRPA133) is not compatible with the
AR12200 and should not be used.
Binding
Always connect three or more remote receivers to the Spektrum Cockpit for correct
linking and binding to a transmitter. Connecting fewer than three remote receivers
will cause the Cockpit to operate incorrectly.
Bind the Cockpit to your transmitter, so:
The Cockpit recognizes your transmitter, ignoring signals from other sources
Transmitter control and servo failsafe positions are set and saved in the Cockpit
during binding.
After charging the batteries
Reset the Cockpit so reliable values for energy consumption and operating times are
displayed.
To reset the Cockpit battery:
With the system powered on, press and hold buttons I and II on the SensorSwitch
together until the following screen appears:
After this screen appears, release buttons I and II and the capacity available is reset
to the value you have stored for the battery capacity.
