Did a great job of tuning, was working on alt hold and loiter and throttle p. Made a dumb newbie mistake. Decided to calibrate radio. Don't know why. Now APM will arm, but I get no throttle response. The motors will not spin. Tried the motors individually in the receiver throttle channel and they work, but not through APM 2.5. Help appreciated thank You.

    My suggestion would be to save your parameter file and reset everything and reload from scratch. Sometimes you just got to format C.
  • What happens if you trim your throttle channel a few clicks down? What is your reported minimum for throttle in MP?
