    sounds like you are in altitude hold or loiter modes, not in stabilise or acro mode...

    Redo ESC calibration too.

      I tried to test it today it had a good stability but the throttle was jerky even when it was at zero percent
      Motors RPM get high for a sec or more randomly and it slow down again to its normal rate while throttle is on fixed rate,this affects on its stability

      I'll make sure the flight mode (stabilize)
      I'll try new RC battery with new calibration

      I'll try to video it for more details


      hope this works

      thank you for reply
