As you go through the calibrate controller procedure, can you see if the yaw and throttle are using individual channels? (If you have a look at the small circles above the ok button you should see if you can move 4 circles individually with the sticks). Sometimes the automatic stick detection gets it wrong, in that case you can click the little circle that you see is the correct one for each channel (instead of clicking ok). I don't own a taranis myself so I'm not going to be able to see exactly what's wrong unfortunately.
That nailed it. The trick is when doing calibration - at the first screen - you center the sticks and click ok.
At first stick detection seems fine, but after that they will affiliate with the wrong circle ;-)
Then for yaw click the 4th circle, throttle the 3rd, pitch the 2nd and finally roll the 1st circle. Hopes this helps also for others. Maybe you could update the manual for the Taranis for future users. Weird problem because the only change was having new Opentx firmware.
Anyway. Now I can fly again !!!
