Hi guys I’m testing a hex, with a wheelbase of of 1610mm, 30 inch props, pixhawk1. I am using Lightware SF11, and IRLock for loiter, u-blox GPS.
I have tested this drone with loiter mode, and the first time it was flyable, without any issues. That was using [3.5.3], default PIDs. Heres the video link:
and the params
I want to show the other result here and please see the flight logs. In the (unstable) log [3.5.4] there is a sudden diverge between the desired roll and actual roll. Auto analysis shows GOOD for most items.
Did anyone experience this? And also what is the best way to tune a large wheelbase hexa? I have read other posts saying ATC_RAT_PIT_FILT and ATC_RAT_RLL_FILT should be set to 10. I have not tried that yet. But in the good flight they were at 20 Hz and that has me puzzled. Please advise, thanks guys!
