My rc joystick channel 1 to 4 works in stabilize mode. But when in alt hold and pos hold it just always remain in center position.
Strangely the night when I use indoor without gps, it works with the althold?
What have I done wrong?
I guess I found the reasons. In case anyone wants to know.
I realised when I turn on my companion computer running scripts with mavlink connected to the flight controller. The RC transmitter will react weirdly.
I just turn it off and everything works fine.
