Tanks fo help,
I think I found what I need:
www.rotomotion.com 6DOF (6 degrees of freedom and servo contrller ) and the price is acceptable.
I foud something even better:
www.micropilot.com MP2028g - but the price tag is huge.
About servo controller resolution, digital servos has 1024 steps so I would like to use that possibility ( I read on this forum that you need this extra resolution for a smooth flight ).
Tanks again, Marek
