I have now calibrated the aux mag as per the video shown earlier. It worked really well. I was then able to calibrate the aux mag with the onboard mag.
just did a flight test. very windy day... but, it seemed to work well, when I put it into altitude hold it slowly rolls one way or the other and keeps going. It won't stop unless I stop it.
I noticed in the video explaining how to calibrate the aux mag that he used a setting of ins13 indoor. it was in french I believe so I didn't really get why?
now that I have the mags calibrated I'm thinking it's a matter of getting things tuned properly.
Any suggestions?
thanks!
