It’s recommended to turn ADC filter off for multirotors to reduce control latency. However it’s a useful feature for wings and planes as it smooths out servo commands and jitters.
ADC filter used to be a global option, it affects all models. But EdgeTX 2.7 fixes that problem.
In EdgeTX 2.7, ADC filter is now an option in the Model Setup page. You can now set it to “Global”, “Off” and “On”.
This is great news if you fly both quads and wings and use different model profiles for them.
