Hi everyone, Ive got a F550 converted to 680 with DYS 65oKV motors and APM 2.6.
Had 3.1.5 installed initially but upgraded to 3.2. Since then I get about a max 1-2 mins flight time on 4S 8500mah battery and no motors spinning on arming. This is completely weird behaviour and since 3.2 cannot even look at the logs properly and no terminal to do reset....
What is wrong with this and how can I either erase the amp and reinstall 3.1.5 or at least fix the issues I am having.
Any advice please grateful accepted.
