Mount your receiver in the
space in front of the APM as
shown in Figure 14. Connect
each channel on the radio to
each of the input channels on
the APM. Tie wrap your cable
into a neat bundle.
While the APM can be
flown with a six-channel radio, I
recommend using eight
channels. This will give you
ample control for more
functionality.
Next, you will install the
GPS unit. First, install a set of
small standoffs, then attach the
GPS to the standoffs as shown
in Figure 15. Connect the GPS
cable to the APM connector
marked GPS. For this GPS unit,
it's the GPS connector on the
side of the APM.
The last APM component to
connect is the telemetry radio.
The best way to install the radio
is to place two pieces of thick,
double-sided foam tape to the
bottom of the radio.
Stick it to the rear of the
platform as shown in Figure 16.
Use some tie wraps to help hold
the radio in place in case the
foam tape fails.
Since the antenna hangs off
the back, I added a couple of
tie wraps to help secure it, as
well. Plug the connector into
the radio as shown. The end of
the connector with the missing
pin is oriented so that it is
facing the power module.
Plug the other end of the
cable into the APM connector
marked Telem.
The top is then added to
the isolation platform and
secured in place with screws.
