Makes sense.

Not trying to make it a point of contention, but the number I remember seeming to be general consensus for safe departure speed is

15 m/sec
=49.2 ft/sec
=33.6 mph

I try to set up my sims to run 17 m/sec or faster off the rod.

32.8 ft/sec = 10 m/sec

Guess I'll be sticking to composites for my Estes tube 2-inch builds. And almost certainly making them shorter, lighter and a little less overstable to resist weathercocking.
