Firstly dead zones is not enabled. Taranis TX with USB connection.
Calibration screen shows all the right responses to the various sticks but when done it shows my pitch stick being 20% lower than centre, it then wont detect any movement in pitch until stick gets away from the centre far enough to suddenly jump to 20% above. Trim on TX has same effect with no change until suddenly jumps above. Using the sliders ingame I can centre it but then it all goes out of whack as now will go out the box at the top and not reach the bottom of the box for backwards pitch. Still has an area of no response aswell so in game just flips forward and back around centre.
Other sims work fine with same model settings (50 range, 50 offset as per guide) and can actually change my ranges to make centre position elsewhere in stick movement with same results meaning its def not hardware related.
