+Little John at Tripoli Colorado Spring Fling 2015. We used a
+[Slim Gem](http://www.quickburst.net/slim_gem_igniter.htm)
+igniter from [Quickburst](http://www.quickburst.net/). Great
+flight! The motor seemed to come up to pressure quickly, and burned
+brilliantly.
+
+The airframe weighed 1200 grams ready to launch, and 982 grams post-flight,
+of which 1g or so was BP in the ejection charge, and a few grams were in
+the Aerotech delay grain.
+
+Post-flight measurement of the phenolic nozzle showed approximately an
+0.330" throat, which clearly indicates some erosion from the 0.291" starting
+point.
