Plugging in the Servos
Plug the servo leads into the appropriate ports in the PowerSafe Evolution.
You are now ready to bind the system.
The PowerSafe Evolution has dual aileron, rudder, and aux 1 channels
available to operate 2 separate ailerons, rudders, or aux 1 or flap servos.
The dual channels use a linear mix to be used when 2 servos are not
ganged on a single control surface such as 2 servos per aileron. Using
dual servos on a single control surface requires the use of either a
matchbox, program mixing with an open channel/s, or mechanical throw
matching. Failure to match ganged servos throughout the range of motion
on a control surface will result in high amperage drawn by the servos, and
will lead to servo failure. Using an inline current meter such as HAN172 is
recommended to minimize the current draw of the system.
Important - Y-Harnesses and Servo Extensions
When using Y-harnesses or servo extensions, it’s important to use
standard non-amplified Y-harnesses and servo extensions as this
can/will cause the servos to operate erratically or not function at
all. Amplified Y-harnesses were developed several years ago to
boost the signal for some older PCM systems and should not be
used with Spektrum equipment. Note that when converting other
models to Spektrum be certain that 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 AR9200 and should not be used.
