fades should be relatively uniform. If a specific antenna is experiencing
a high degree of fades then that antenna should be moved to a different
location.
8.
A successful advanced test will yield the following:
H - 0 holds
F - less than 10 frame losses
A, B, R, L - Fades will typically be less than 100. It’s important to compare the
relative frame losses. If a particular receiver has a significantly higher frame
loss value (2 to 3X) then the test should be redone. If the same results occur,
move the offending receiver to a different location.
Flight Log
If you do not have a telemetry capable Spektrum transmitter, the Spektrum Flight
Log (SPM9540) is also compatible with the AR9140T, AR12310T and AR20310T
PowerSafe receivers.
The Flight Log displays overall RF link performance as well as the individual
internal and external receiver link data. Additionally it displays receiver voltage.
Using the Flight Log
After a flight and before turning off the receiver or transmitter, plug the Flight Log
into the Data port on the PowerSafe. The screen will automatically display voltage
e.g. 6v2= 6.2 volts.
When the voltage reaches 4.8 volts or less, the screen will flash
indicating low voltage.

Antenna fades
Represents the loss of a bit of information on that specific antenna. Typically it’s
normal to have as many as 50 to 100 antenna fades during a flight. If any single
antenna experiences over 500 fades in a single flight, the antenna should be
repositioned in the aircraft to optimize the RF link.
Frame loss
represents simultaneous antenna fades on all attached receivers. If the RF link is
