Hi guys, I have an flight with my 24inch quadcopter.
When I auto takeoff via QGC, the drone climb so fast, you can see the RCOU, I don’t know why. Fortunately, it’s not crash and still have a good Loiter performance.
Pls check the logs and give me some advice. Anyway, the MOT_THST_HOVER should be set at maximum takeoff weight hover, or minimum TOW(No load) ?
Thanks!

I’ve found it to be less than ideal using the QGC “Take Off” slider. It operates the throttle as if you are taking off manually, to about 70%. This causes quite an altitude overshoot if your copter has a good thrust to weight ratio.
It’s much better to just take off your self in Loiter. You could try Take Off mode from the list.
There are two parameters that control the takeoff aggressiveness. I do not remember their names right now, but they are included in the ArduPilot methodic configurator software.
We use them very successfully on > 100 Kg vehicles and they work like a charm.
If your load varies, its best to just set MOT_HOVER_LEARN to 2 and forget about it.
Besides, what @amilcarlucas mentioned to let it learn by itself. I am not sure whether you are aware of aircraft designed to carry large, directly mounted payloads?
Thanks for your help, buddy!

So that’s why! I countered this by setting psc_jerk_z to a higher value as suggested by @dkemxr. And no wonder why the QGC takeoff works while the MissionPlanner TakeOff doesn’t for me, although the exact cause is unknown
