controller or receiver manuals.
DSM2/DSMX are typically used by Spektrum controllers
SBUS is typically used by Futaba controllers
Pitch/Roll/Yaw/Throttle
The Pitch, Roll, Yaw and Throttle controls are the basic flight controls and are mapped to the
two radio controller sticks.
Mode
The required Mode Switch selects between the three different flight modes: Manual,
Altitude, and Position. A three-position switch is recommended to select the three different
modes. However, a two-position switch may be used, but will only allow for selecting
between Manual Mode and (depending on radio controller mixes) either Altitude Mode or
Positon Mode . Other modes are available, but should be only used by experienced operators.
Return to Home Switch
The optional Return to Home Switch selects between the different Return-to-Land (RTH)
functions. At minimum a two-position switch is required for the Home Switch functions to
select between RTL Off, and initiate RTL functions.
Typical Channel Mappings
The following radio channel mapping configurations are recommendations only and can be
set in ALTA QGroundControl. Depending on exact radio models, these may help as an initial
configuration. However, it is up to the pilot setting up ALTA X for flight to determine if these
settings are appropriate.
