same here, but Sophies back tonight so i better clean up the room a little..
i thought the 3001 was a ballraced 3003, umm the 3004 sounds interesting. my Capiche is currently on 4.8V, but only because i cant find a 1850Mah cell to match my pack, guess i'll have to bite the bullet and get a decent 6v pack sometime. it's the easiest way to get the 591's up to 3003 speed for the time being.
strange how the 3003 is meant to be the 148's replacement ( all robot built rather than some done by hand on the 148 as i understood it ) but the 148 is still considered the better servo. guess that have such a good reputation, i've got prehistoric ones that are still up for the task.
