Just got a IRIS+ and after a few days of flying decided to update the firmware to 3.3.2 from 3.3.1.
After loading the iris+ parameter settings back from the default iris+ file, and adjusting battery settings to get things back to normal i noticed a major change in flight behavior. In loiter mode, my old configuration really had a stiff loiter response when going dead stick, after this upgrade, the loiter mode is ‘sloppy’, it seems to be working but it drifts are quite a bit more and doesn’t stop the iris+ quickly when the inputs are released.
I read about vibration causing poor loiter performance, but pulled the logs and looked in the ‘vibe’ group and the values seem to be in spec. (<10). the only thing is, i don’t have any of this data from the old firmware, because it did not exist in those logs.
- can someone help me figure out why this is happening? what should i check?
- i’d like to get a screenshot of the old settings and compare to my new parameter settings, should i just load the old firmware back in and compare the values?
