our heavy drone has problem with wind, in the wind be very unstable.
it is stable on stabilize mode and if i fly fast and turn it to Alt hold mode or loiter mode, the copter gets unstable (almost crash)and i have to quickly switch to Land mode.
the config is like below:
1- motor - T-Motor U12 90KV Brushless
2- Esc - FLAME 60A 12S V2.0 Multi-Rotor Drone ESC 12S Controller
3- Black cube
4- centre to centre is 1400 mm
5- Prop is 32x11 T-motor
I have attached the all log files for last flight .
There are suggestions above to use AutoTune and then the very extensive Methodical tuning method but really, for new users not very familiar with ArduPilot these are both overkill.
@amilcarlucas, I really think we should not recommend that every person with a tuning issue try the methodical method. It’s very complete but too much for most users I think.
Yes @rmackay9, probably most users do not get any issues nor problems using the wiki tuning instructions.
But those users do not come to the forum posting their problems.
The ones that do, and do get problems, need something more elaborated because the method they used obviously did not work.
I do not think that is an overkill (so far no user that used got an unstable vehicle), and some that use the wiki do become unstable (because often required steps are skipped).
But I do plan to post a shorter version that stops before the autotune and relies only on the quick tune.
