I just built my first DIY quadcopter using the drone kit. Maybe I had false assumptions on self build drones, but I’m surprised at the high instability when hovering at a stationary point. It sways around like it’s drunk, sometimes more than 2 metres in every direction. When looking at videos of other drone builders, this seems to be a common problem with self built drones.
So far I heard of 2 ways to remedy that:
- Using an RTK system, e.g. Here3 + a ground station
- Using an optical flow module, e.g. a PX4Flow
Does anybody have any experience with one of these? Is it worth investing in either one or should I just live with it? Or is there another option?
