It is supposed to be a simple hinged lifter. The plan was to over-volt it, but I was warned against it on my last stint in these forums.

To the original question; Can anyone give me the speeds of any linear actuator they use, or any that they know is in use, so I can get an idea for the typical speed. Or, I suppose to put the direct question at you, is 2.8 cm/s too slow, because it seems it to me.
