3DR pixhawk & tarot650 build
Can I ask if someone here could help with reading a couple of short flight logs
Reason being, I've over the last doz or so flights tweaked my advanced settings and felt I had my tarot650 flying well, today I tried out the autotune (as u do!) and the settings changed quite significantly. I followed the methodology of saving the settings and checked them via APM and was quite surprised at the differences, I then decided to take it for a short flight (and it was) to test before perhaps changing them back.
PIDS as below v3.1
Rate Roll Rate Pitch
Before: After: Before: After:
P: 0.1750 0.1000 0.1750 0.2500
I: 0.1650 0.1000 0.1650 0.2500
D: 0.0080 0.0020 0.0080 0.0150
IMAX 500.0 same same same
now looking at the Autotune settings they should have set off alarm bells I'm thinking? however I did a short flight after doing the autotune and whilst it felt a little less responsive didn't show anything that I thought was extreme.
Decided to test fly on the new settings again before perhaps changing back and result was get airborne change to althold, and within a short time things got interesting a roll wobble developed and continued to worsen until I powered off and experienced an uncontrolled decent which ended as these things do.
I guess as I have little experience with this I would like to discover whether the settings were the cause of the loss of control of whether something else happened coincidentally
I do have the logs downloaded via APM but not sure on how to load them up.
thanks
