It seems that the longer this thread runs, the more of the "... don't
forget you also need..." posts.

does anyone have a beginneers guide on how to select and connect
servo's and such ?

I have a few DC motors from old printers with encoders, and a few tiny
pressed can steppers with what I think is an encoder. (more likely a
revolution counter)
