I have charenged of CUAVv5 using QGroundControl. QGC is simple and useful GUI.
Setting up the sensor wasn't too difficult, but I had a hard time setting up the wireless, because I didn't read the manual properly. I purchased a SBUS communication product - RadioLink T8S - for RC control. It involve R8EF tranceiver.
I showed result of basic setting for Rover.
And I learned USB-setting by MissionPlanner. I could connect to MissionPlanner.
