I am not sure if this is hardware or software or a param. I thought it must be hardware,but I replaced/swapped around motors and esc on number 1 and 2 arm. I think it just started, if not then I didn’t notice it before but it is hard to believe. I made some videos of whar ir is doing. there are 3 videos, sorry for the quality. I am running ver 3.2-rc5 but it started while using rc4.
here are the videos (the beeping is a bad battery cell but this happens with good battery too)
I also attached the log for these flights in the videos
thanks for any help, this one is really driving me crazy
