HI all, I’m kinda new to this platform and I made my first test flight yesterday with a Pixhawk 4 mounted on a custom frame, (2.2kg takeoff weight, 570mm base wheel). I used the Holybro s500 frame in the QGroundControl setup and used default gains. During my first flight I noticed low frequency oscillations and the drone was very unstable, it has been very hard to land it successfully. I guess I have to tune the PID controllers but I’m a noob with PX4 and I wonder if someone could take a look at the flight video and suggest a correct procedure in order to tune my quad.
Thank you in advance and any recommendation is well accepted
