2. Mount the switch on the side of your aircraft and insert the switch plug
in the port in the main unit marked SWITCH.
Note: The PowerSafe uses a specifically designed switch. Conventionally wired
switches are not compatible with the SmartSafe.

1. Using foam or thick double-sided foam tape and tie wraps, secure the
main PowerSafe unit in the position where you would normally mount
the receiver.
Installing the PowerSafe Main Unit
Installing the Batteries
Using the given guidelines select the battery system that best fits your
application and install the battery(s)/regulator(s) in your aircraft. Connect
the battery to the PowerSafe. Spektrum batteries are pre-wired with an EC3
connector and plug directly in. If using another brand of battery it will be
necessary to solder EC3 connectors (two are included with the AR12100)
to the battery leads. If using a regulator, install it per the guidelines
included with the regulator.
Mounting the Remote Receivers
Antenna Polarization
For optimum RF link performance, it’s important that the remote antennas
be mounted in an orientation that allows for the best possible signal
reception when the aircraft is at all possible attitudes and positions.
This is known as antenna polarization. This allows the greatest exposed
visual cross-section of the antennas from all aircraft orientations. If three
antennas are used, it is recommended that one antenna be mounted
vertically, one horizontally in-line with the fuselage and one horizontally
perpendicular to the fuselage (see illustrations on pages 11-12). This
covers the X,Y and Z axis offering superb cross-section visibility in
all aircraft orientations. An optional fourth antenna can be added at an
intermediate angle offering even greater RF link security and system
redundancy.
Locating the Remote Receivers
While Spektrum 2.4GHz systems are far more resistant to interference
caused from internal RF generating sources, the remote receivers should
be mounted as far away as practical (typically 4” or greater if possible)
from the following:
• Ignition systems
• Ignition batteries
• Ignition switches
• Engines
