I would appeciate if you can help me with some tests.
I made a new build of the app along with a scibble test app.
With the scibble app you can make sure the inputs are maped correctly and if not directly see whats wrong.
You can play around with the parameters in the scribble.sh script by setting rotation, invertx and inverty from auto to different values.
if you see the rotation and direction is right but the scaling is off try to set touchscreen_flip_axes_limit=1.
Plese post your model and your results and i can make sure it works out of the box for the next release.
It is too big to attach so you can download it here.
