Thanx, M-Dynamics, this hard edges was the only thing in your model that I was not sure in. I do not try Mike' method to fillet it, but as you say it looks like impossible.
On the reference image those edges are smooth, so I decided to try if it possible to make it with loft) I tried this method when I saw joystick first time, but unfortunately I could not manege to make this form.
After that I had some experience, and tried to do it again today and I managed to make it. This loft method in this case require a bit experience, to understand how it bends surface. It's more complex than all forms I made before.

Pilou, I'm not sure what do you mean, could you tell it in another words?
