I've posted about this before, trying again - maybe I once can actually fly this thing. (video's based on current released version, a day old or so.)
It's on Ubuntu, everything else works fine with the interlink "radio"
FPV Freerider, behaves randomly at calibration, messes up inverting, range, gives asymmetric range (cursor goes much more one way than the other) - and - maybe sometime gets it right. - but still impossible to achieve perfect symmetry.
Then - it does no good, because when the app is restarted, the shitstorm starts again, it even looks like where the throttle is when starting the application, influences how badly, it will be off, requiring the awful calibration again.
Please ! - make a normal, decent calibration like any other application, I've never seen a complex mess like this, with lots of sliders, - and still are unable to get good calibration every time.
