Scratch, wear and tear on the cam surface

[ozairshafiq]

So, on my gunfighter mk.3 using the default avia-s cams.

I got heavy scratches or wear and tear on the cam surface. I am not sure if this a cause for concern and if I am doing something wrong with the assembly. I had issues with the cam alignment. Upon receiving advice, I tightened the nut and the bolt so the cam seems stay put and be lined up well.

For my use, I have strengthened the dampeners on both axis. I have noticed that If I make large inputs on either axis, the stick moves smooth as butter. But If I try to make small minute corrections, then there is a lot of sticktion in the movement or bumps. Is this a natural cause of strong dampening or should the travel be smooth either way?

For reference, here is picture of the surface of the scatch on the cam in the pitch axis.

Seems like your cam was not secured by the bolt. Please do not use it anymore until you'll see this video and adjust it accordingly.
With the dampers that's normal behavior. If you want a smooth motion while the dampers are tightened up you'll have to use a bit of grease (Nyogel 767A preferably) between the metal barrel and the nylon pads that are tightening around it. This might interfere with the stick returning properly to center position, but you could overcome this by changing cams (hard cams), or installing heavier springs, or increasing the deadzone.

I tried avia-h with two #30 springs and loosened the clutches, the stick would always come back to dead center.

Currently with tightened clutches and using two #30 springs with 200m extension and avia-s cams. The stick does not come back to center, its always off. Is this expected behavior?

Definitely. For 100% guaranteed return to center start from hard cams, heavy springs (#50 and #40 on each cam), dampers completely off, no extension, deadzone 1. You could adjust from there.
If you really want a proper return to center on your current setup try adjusting the deadzones on X and Y; increase it with about 0.5 until you hit the dead spot.
