[RocketsNW] Fins on a Minimum Diameter

[Jeff Moore]

The rocket did 10,750 ft on a K550 on it's maiden voyage.  The motor section 
separated from the tether between the two sections and came in on a flat 
spin and landed about 25 ft away from the rest of the rocket w/o a scratch 
on it.  The airframe is carbon fiber aerosleeve over phenolic tubing.  The 
rocket is over 7 ft long as it was designed for  hybrid motors as well as 
solids.  The motor section is approx. 50 inchs long by itself.  It's pretty 
stout.

p.s. The rocket is actually not finished yet, it still needs a final coat of 
epoxy to fill the weave of the carbon fiber and fiberglass sections.  This 
is the lowest level of performance I expect from it.

Thanks for all your help!

Also, to Jeff Moore, how did the flight go on your minimum 54"? The
wire/kevlar thread idea around the fin can sounds robust, and you didn't
have any problems with cracking around the holes you drilled?
