Hello Everyone,

first of all - a general warning - always make sure you disarm your copter before getting your hands into it. -->> Also make sure to test if it really has been disarmed by e.g. pulling the throttle again up before approaching. <<--. I thought i disarmed mine today after i crash-landed it during Position hold mode and hit the throttle with my belly - end of story has been a visit to the hospital.. -

But back to the problem which i have seen:

I waited until i had 3D GPS lock.

When i take off normally in stabilize, everything seems to work (as far as i can tell after maybe a total time of 30 minutes flying..). I thought then i would switch to position hold - also the APM via PC and telemetry confirms me switching to this mode, so setting PosH works.

Now i have seen two behaviours:

Try 1.) It started flying a small circle (about 270°) and then it started rolling to 45° and going approx. 50m in one direction (to the right) until i pulled the throttle low and it crash-landed.

Try 2.) (different location) Almost immediately after switching to PosH, the copter started tilting left to 45° and started to go really fast until i crash-landed again.

The first attempt circling looked really good, but then it started to go crazy.

Is there some home-location i have to set ? - Why should the copter decide to go in one direction ?

I left all sticks except throttle centered during both tests. Normally, i think they are really centered as the copter only moves to 45° when i heavily push a stick to one side.

Does anyone know why i see this behaviour ?



i have got my quad finally flying.

    Hi Florian,

    I have read your other posts so that I have a bit of background.. Is this the quad or the octocopter that you have this problem with? and what are your PID settings for loiter?
