Channel Limitations - Spektrum SPMAR637T Manual

Differences between Self Leveling/Angle Demand and AS3X modes
This section is generally accurate but does not take into account flight speed,
battery charge status, and other limiting factors.

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.
