<<A 6-7 second dive? You've timed it? That's a LOOOOOOOONG time, you must be nearly a dot when you start the dive. I suspect your dives are a lot shorter than that. >>

Enough time for a fellow standing behind me to say to another "Watch this." And for the other fellow to say "Yeah, Charlie is always worth watching, snicker, snicker."

40 mile/hr * 1hr/60min * 1min/60sec * 5,280ft/mile = 58 ft/sec

58ft/sec * 7 sec = 406 ft , so if it was a fairly steep angle of -60º (sin60º=0.866) and 406 ft is the hypotenuse, then that allows for 400 ft of altitude with a 355 ft vertical decent and still 45 ft to pull out. 400 ft isn't all that high. I plugged the 40 mph, but I start slow and build up as it desends, so it probably is close. I fly thick winged 4-strokes that don't tear up the sky. Seven seconds in a Quickie 500 would put you four seconds underground.


Who says I wasn't paying attention in trig class?
