I am in the process of getting used to my new GX12 radio - and noticed some jitter on the gimbal channels - while the Boxer I have been using for a few years shows rock solid values.
Long story short - turns out I had some filtering enabled on the Boxer radio (must have been by default) and it is recommended to disable them for quads (they are good for wings).
First flights today with the new settings (flying my whoop in a very confined place) - and I could swear I am now managing to avoid hitting obstacles a lot better… Not done full A/B testing but seems the reduced latency makes a noticeable difference - so check your filters
