Hello,
I didn’t used the quadcopter for long time, now updating the ground station application I found that the OPT list BOX for RC 7,8,9,10 are empty.
In the past a simular topic has been open “Copter Extended Tuning screen Ch7_OPT/Ch8 Opt update for Copter-3.7 #2070”
I consider solved the topic due to this : I installed Mission Planner on another PC all is working, may be the installation on the first PC isn’t good. I’ll try to uninstall, clean and re install.
