Greetings. There is such a question. I connect the TX16 remote control as a joystick to a computer with QGS. The quadcopter is connected via USB to the computer. In QGC, it is possible to configure channels starting from ch9 ch10 only as buttons. That is, the channels ch5 ch6 ch7 ch8 for which the toggle switches are assigned in the joystick mode do not work.
In MissionPlaner, I have TX 16 and arm disarm works fine on RC5. Change of flight modes on channel CH6. Can the joystick in QGS also work in three-position burning channels.
