Guys I need your help on this one.

Some days ago I wrote you about a problem I am facing with the swash plate's travel. On these 2 videos you can watch the travel in both modes.
The problem is that if a set up the pitch to be 0 at middle stick and 3D on, then the heli won't leave the ground. If I add pitch, as I did, it flies ok, but it's impossible to have negative pitch

I need you to watch closely those travel distances of mine ,compare with the ones on your helis and tell me if mine are correct or less.


The first is a close up of the swash plate at Normal mode (not 3D).

The second is the same at 3D mode.

And it flies like this
