First time posting, i'm working and succesfully flown once a coaxcopter, with a smaller motor than the one in the picture.
Now i'm having issues with thrust power, and i'm pretty sure is because it's not propperly calibrated, because the coaxcopter weights 1kg and the motor thrust is about 1.3kg (motor: https://hobbyking.com/en_us/contra-rotating-bl-system-375w.html) .
i'm using an old APM 2.5 with a custom firmware installed version 3.2.1. Already did PID calibration.
I don't quite understand these parameters, i think these are the problem but haven't figured out yet.
Any help will be very usefull.
i attach also full param list
