Configuration > Output > Output Configuration
I was wondering if it was possible to Assign the "Update Rate" of each channel separately. I just hate that and wonder why channels are Grouped like that? This way if I want to use Ch 3-6 for quadcopter and use 1,2 for say Alarm, Servo Gimbal etc it is simply not possible to set update rate of 50Hz on Ch 1 and 2 and 490Hz for rest.
In the Configuration > Vehicle > Custom
it is possible to set any channel to Roll Servo or Accessories but if you cant change Update rate to 50Hz individually its kind of useless.
