I haven't got my drone out in about 3 years due to health issues. So today after reading for about a week about open solo and side pilot on IOS 14. I put open solo 4.0.0 then did all my pre-flight stuff took off and the right stick done nothing all I had was throttle up and down/height on the left stick and had to do a crash landing. Tried it again the same thing. I didn't get ten feet off the ground no wind perfect flying conditions. Have I lost all the flying skills I had or did one the update not take correctly? I did the Factory reset partition and clean install (not at the same time) of the open solo on copter and controller.
