Thank you for your help, I will upload the picture latter, however, i wish to recheck the work of parameters, so i use matlab to plot both raw data and calibrated data. From the picture above, I think there must be something wrong in my calibration or data, could you help check my data, or do a calibration for my data."
I have not done a calibration with an AQ board with a DIMU but I will start doing one today. After I get a good result I could then be of some help to you.
The AQ boards with a DIMU fly very well without doing a calibration. I see there is some sensor problems when flying in very cold conditions so that's why I'll do a calibration on my boards now. My outside temperature is 0 degree Fahrenheit this morning.
Your AutoQuad Log Viewer plots look good to me but until I do a calibration I'm not sure. I would follow the instruction and do a calibration with them.
