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.
ModelMatch
™
Some Spektrum and JR transmitters offer a feature called ModelMatch that 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 onscreen.
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 Spektrum Aircraft Modules do not have ModelMatch.
Tips On Using 2.4GHz
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 channels have no output pulses. 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 channels have no output pulses. The
