Tim is also suggesting the Velocity at Deployment is best under 50 mph which seems to be a much higher than the 20 mph that most rocketeers use as a standard.
Also Tim stated that the Velocity at Launch Rod Departure should be at least 30 mph to make the fins effective for stability.

The deployment velocity that Craig and I have been shooting for is 20 *feet per second.* Guys, what does 50 mph translate into f.p.s.? (I'm nowhere near RockSim right now.)
