Hey Jack does this mean I have to buy a 24mm Cesaroni case? Not a problem,
just curious because these sound pretty "interesting".

I put sealed balsa fins, clipped delta style, 3/16" thick, on a bashed
Estes SkyWriter and it didn't survive the transition through mach on an AT
single use, 24mm F. Jack G. still delights in busting my chops over that
flight. It was an impressive shred though; biggest piece left was the nose
cone.

I realize the planform makes a big difference because of flutter. Just
curious because I been simulating some of my paper and balsa 24mm MMT
rockets using the newly cert'd CTI 24mm loads. The F240VM gets into the
800ft/sec range! (For comparison an D15 is 230 and an E28 is about 450 ft/sec)
