Vehicle mass and Inertia, airframe setup for real drone

Hi everyone,
I am new to px4 autopilot and I have the problem that how I can setup the vehicle mass and Inertia to my real drone and also the airframe like arm length. I can not find the parameter named vehicle mass in Qground control to make the change. So could you please guide me to find the way to input these parameter? Tks!

@ducanh1699 Normally you don’t set the vehicle mass in the configs.

If you are new, please checkout the “Getting Started” section of the PX4 docs: Getting Started with PX4 Autopilot | PX4 User Guide

This document should have more or less everything that you need to know to fly with PX4!
