### Description
|
||||
The rc_update module handles RC channel mapping: read the raw input channels (`input_rc`),
|
||||
then apply the calibration, map the RC channels to the configured channels & mode switches,
|
||||
low-pass filter, and then publish as `rc_channels` and `manual_control_setpoint`.
|
||||
|
||||
### Implementation
|

To reduce control latency, the module is scheduled on input_rc publications.
