Joe It is going to depend on where you position the anchor point in relation to the pivot of the board. The closer to the pivot point the faster it will open and close, however you will need a lot of torque to do that but a shorter actuator. The further away will take longer, less force and a longer actuator.

Is that fast enough?

They also have 4" and 12". I think from what I've read 6" should be ok. Any advise? http://www.everestpartssupplies.com/products/new-heavy-duty-linear-actuator-6-inch-stroke-225-pound-max-lift-dc-12v-12-volt Paul Visk Belleville Il. 618-406-4705
