STB_PIT_P and STB_RLL_P

Posted by Bob Kirkpatrick on April 19, 2014 at 12:43pm

My Iris has STB_PIT_P value of over 7 and STB_RLL_P of over 10 and Droneshare flagged them as bad entries. The APMCopter manual says values of 3.0 to 6.0 are the acceptable range. I wondered if Pixhawk had a different value range and if these values were factory set for a reason. Can someone give me some education on whether I should change these values and what I should see by raising or lowering the values?

Thanks!

    Ah.  I've updated the max to be 12 in the parameter descriptions.  I think this is what DroneShare uses when flagging params as having a bad value.  Txs for the report!

    For as long as it flies well then I shouldn't be worrying much on that. I don't care if it's 7 or below that number. I think what matter's most is the performance.

    This is the params they load at the factory https://github.com/diydrones/ardupilot/blob/master/Tools/Frame_para...

    7.0 and 10.0 are correct.

    PS: the only parameter there that makes it easier to learn, but should be increased is Angle Max. It should be 4500 (45Deg) to be able to handle windier conditions.

      Thank you. I'll leave them be and make the Angle Max change you suggested.
