Hi andor,
You're one lucky and early owner then

Welcome to the metal gimbal world!
In Europe people are not even allowed to throw their money to pre-order the Gladiator Pro
[ EDIT: I obviously assume you own a Gladiator Pro, but Jason should be aware if there's some Pro already shipped - so I hope no one is wasting time here
]I don't think there's a detailed manual including the gimbal technical details yet, but it should be identical to the Black Mamba MkIII gimbal.
About the cams :- the 10 one gives the soft center feeling
- the 30 one gives the hard center feeling

For the
springs, unless you have a more detailed information,
there's that thread (w/ picture).(assuming you received similar springs)
For the advanced configuration, you'll have to refer to that reference thread. It's a dive into complexity, so I'd suggest you only take that road if you really want to achieve some very specific configurations

And don't hesitate to ask your questions on the forum. VKB and a bunch of enthusiasts will drop by and try to help.
