Per the linked post:

e.g. if you set an output’s servo channel function to `Actuator 1 (184)` then you should be able to use the `servo_1_*` button functions in QGC to control it. In updated software you should be able to use the `actuator_1_*` button functions instead - they’re the same functions, they just use a new name.
