@coreyazion I was able to switch to position flight mode and the drone flew better in position flight mode. In my previous testing I had issues with position flight mode with drifting but in my most recent attempt it flew much better and was relatively stable. I did experience after a short while some more drift towards the back-left of the drone however I am unsure if this is due calibration or configuration. I also experienced the same issue with PX4 Hold mode.
Thanks @tom much appreciated. Received the file.
Was following the instructions as mentioned here https://docs.modalai.com/calibrate-cameras/ for better understanding of calibration files.
