Need Help on Loiter and Altitude Hold mode setting

Posted by Rajat on February 26, 2015 at 1:50am

Hi All ,

I need some help to set the loiter and alt hold mode for my APM Quad , I was trying to fly the quad with any of these two flight mode.

The Issue I am facing is when I switch to any of this mode my quad start abnormal behavior and start to climb up very quickly . All though my purpose  to fly my quad in this mode is to get a stable flight so that I can hold the quad on one position and on certain height but unfortunately  the quad crashed up with the ceiling and I lost two arms and propeller  :(

Can anyone help me with this and let me know how can I achieve the stable flight with these modes .

If there is any other solution available other then this modes then please  let me know

    What version of firmware are you using.

    Are you taking off in STABILIZE mode, first? This sets THR_MID based on a calculated mid point for the throttle, then when you switch to loiter, Alt-hold, or Pos-hold based on the current weight of your multirotor. If your weight of the multirotor doesn't change, you can fix this value in Mission Planner based on a review of your log file (you still have to fly a Stabilize flight to determine this value at least once). This will fix your climbing problem when switching modes.
