Thank you so much. I will try tonight.
So, first I calibrate using the game controller of Windows control panel.
Then, I recalibrate using Realflight.
But still, if I had previously trimmed any particular plane, it will go back to that trim for this plane.
So, I would have to listen to that tone of the trim buttons to make it happen.
I think I get it.

One last question and I promise not to bother more: are those planes designed by users fly like the real model?
Just l;ike those that come with the program?

Thanks,
