This was my first glider flight, so I didn't really know what to expect.  I loaded a 1/2A6-2 and let 'er rip.  The Sparrow boosted in a wide corkscrew to maybe a couple of hundred feet, and ejected right in the sun so I couldn't see a thing.  After loosing sight of it, I sighted the rocket actually gliding to a stop a hundred yards down wind.
