So I can supose that you can see how the trottle and roll moves in that sceen, isnt it?
Yes, it moves as I play with remote.
In the flight data window you can change to Manual mode, please try it.
I did. Also I have downloaded the params and loaded them into APM Planner. It told me '56 params were changed'.
However, the rover still reacts only on steering control, not on the throttle.
I can see the 'TH' led on the RC transmitter is red, while 'ST' is green.
Also I can see such a picture in the APM Planner:
When I turn the steering control wheel, I can see both 'Radio IN' and 'Servo/Motor OUT' change simultaneously for 'Radio 1'. However, for the 'Radio 3' only the 'Radio IN' bar moves.
