Installing the Batteries
Using the given guidelines, select the battery system that best fi ts your application
and install the battery(s)/regulator(s) in your aircraft. Connect the battery to the
receiver. 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 AR12120) 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 attitudes and positions. This is known as antenna polariza-
tion and 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 below).This covers
the X,Y and Z axes for superb cross-section visibility in all aircraft orientations.
An optional fourth antenna can be added at an intermediate angle to offer even
greater RF link security and system redundancy.
