ok. Got everything working after a lot of hassle. Had a lot of problems calibrating, but finally it come along, and everything was good.
I have mounted a GoPro3 black at the top for fpv, and a Samsung NX1000 in the gimbal. Big problems with the gimbal.. It trembles (shivering) a lot. The servos has got some issues. Anyway.. ordered a brushless gimbal,- so will not make any effort in fixing this issue. (the seller takes it back in change of a new one).
Uses 4s lipo, and have mounted 2 of them. Also flying with one battery, but then it is mounted on top.
