RE: B.A.S.E Jumping
From the time the servo is activated until open canopy is only about 2 to 3 seconds. We do not use slider to slow down the opening of the canopy. We dropped a diver from a burning plane earlier this year and he was only about 50 feet, maybe 75 at the most, and his chute was deployed and under control before he touched down. I don't recommend doing this from 50 feet all the time, but in time of need it worked for us. I will add this was without a drouge chute attached, the chute mite even deploy faster with the use of one of our druoge chutes. Plus, depending on how you use the drouge chute you can slow your descent down before the chute opens.
