Flight Log (SPM9540 Optional)
The Flight Log is compatible with the AR6115(e). 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 AR6115(e). The screen will automatically display voltage e.g. 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 the internal antenna
B - Not used
L - Not used
R - Not used
F - Frame loss
H - Holds
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 performing optimally, frame losses per flight should be less than 20. A hold occurs when 45
consecutive frame losses occur. This takes about one second. If a hold occurs during a flight, it' s
important to evaluate the system, moving the antennas to different locations and/or checking to
be sure the transmitter and receivers are all working correctly.
Note: A servo extension can be used to allow the Flight Log to be plugged in more conveniently.
On some models, the Flight Log can be plugged in, attached and left on the model using double-
sided tape. Mounting the Flight Log conveniently to the side frame is common with helicopters.
Tips on Using Spektrum 2.4GHz
ModelMatch
™
Some Spektrum and JR transmitters offer a patent pending feature called ModelMatch.
ModelMatch prevents the possibility of operating a model using the wrong model memory,
potentially preventing a crash. With ModelMatch each model memory has its own unique code
(GUID) and during the binding process the code is programmed into the receiver. Later, when the
system is turned on, the receiver will only connect to the transmitter if the corresponding model
memory is programmed on screen.
Note: If at any time you turn on the system and it fails to connect, check to be sure the correct
model memory is selected in the transmitter. Please note that the DX5e and Aircraft Modules
do not have ModelMatch.
While your DSM equipped 2.4GHz system is intuitive to operate, functioning nearly identically to
72MHz systems, following are a few common questions from customers.
1. Q: Which do I turn on first, the transmitter or the receiver?
A: If the receiver is turned on first —all servos except for the throttle will be driven to their preset
failsafe positions set during binding. At this time the throttle channel doesn't output a pulse
position preventing the arming of electronic speed controllers, or in the case of an engine
powered aircraft, the throttle servo remains in its current position. When the transmitter is
then turned on the transmitter scans the 2.4GHz band and acquires two open channels. Then
the receiver that was previously bound to the transmitter scans the band and finds the GUID
(Globally Unique Identifier code) stored during binding. The system then connects and
operates normally.
If the transmitter is turned on first—the transmitter scans the 2.4GHz band and acquires two
open channels. (When the receiver is then turned on, for a short period (the time it takes to
connect) all servos except for the throttle are driven to their preset failsafe positions while the
throttle has no output pulse.) The receiver scans the 2.4GHz band looking for the previously
stored GUID and when it locates the specific GUID code and confirms uncorrupted repeatable
