USING A FLIGHT LOG—OPTIONAL
The Flight Log (optional) is compatible with the AR8000 receiver. The Flight Log displays overall RF link
performance as well as the individual internal and external receiver link data. It also 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
AR8000 receiver. The screen will automatically display voltage i.e. 6v2= 6.2 volts. Note: When the
voltage reaches 4.8 volts or less, the screen will flash indicating low voltage. Press the button to display
the following information:
A - Antenna fades on internal antenna A B - Antenna fades on internal antenna B (not used on the
AR8000) L - Antenna fades on the left external antenna R - Antenna fades on the right external
antenna (not used on the AR8000) F - Frame loss H - Holds
Antenna fades—represents the loss of a bit of information on that specific antenna. 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
performing optimally, frame losses per flight should be less than 20. A Hold- occurs when 45 continuous
frame losses occur. This takes about one second. If a hold occurs during a flight, it's important to re-
evaluate the system, moving the antennas to different locations and/or checking to be sure the transmitter
and receivers are all working correctly.
Note: Use a servo extension to allow the Flight Log to be plugged in without having to remove the
aircraft's hatch or canopy. On some models, the Flight Log can be plugged in, attached and left on the
model using double-sided tape. It is common with helicopters to mount the Flight Log to the side
frame.
