Channel Limitations
The AR637T+ can use up to seven extra channels for AS3X+ and SAFE
functions; one for Flight Mode selection, one for Panic Mode, and up to five for
Gain. You may use any channel up to 20 that is not a control surface or throttle
for these functions, and you do not need to use channels 5 and 6, keeping those
channels and ports on the receiver open for normal servo operation. However, you
may run into channel limitations depending on the number of channels on your
transmitter and the number of channels you are using on the receiver.
TIP: If you are experiencing limitations because of channel count, here are
a few options;
• You can operate the AR637T+ without a channel assigned to Flight Mode,
but you will only have access to AS3X+ options, not SAFE.
• You can set up one self-leveling mode to serve as Panic Mode so you don't
need to dedicate a separate channel for Panic Mode.
• You can operate the AR637T+ without a gain channel assigned, and just use
fixed gain values throughout the configuration. To do this, first assign flight
mode to a channel, then change all gain values to fixed for flight mode 1,
then you can unassign the flight mode channel and it will remain in fixed.
Flight Log
Flight Log data can help you optimize the control link for your aircraft. Flight
Log data is displayed on telemetry capable Spektrum transmitters.
Using the Flight Log
A - Fades on main receiver
L - Not available on AR637T+
F - Frame losses
Fades
Represents the loss of one bit of information on one receiver. Fades are used to
evaluate the performance of each individual receiver. If a fade value is showing
higher than the others, inspect or reposition the antenna to optimize the RF link.
Frame Loss
A frame loss occurs when one complete data packet is missed. A single frame
loss does not represent a loss of control, but frame losses should be monitored.
In the air it's normal to experience as many as 100 frame losses per minute
of flight. On the ground the number of frame losses will be higher because the
signal is hampered by the dirt and moisture.
