Last flight of a great day.  37 flights total, 19 different rockets, 12 maiden flights.  Fifteenth flight of the day for the BS.  First time I've ever been brave enough to stick a D-10 in a Black Shadow.  Used my new Pratt Hobbies Go-Box.  Tried to use a Quest Q2G2 to light the motor but no dice.  Used an Aerotech igniter with no problems.  Off the rod like it was shot out of a gun!  Dead straight and way up there.  Had no problems tracking it.  Arcing over at the top of the climb, looked to be just past horizontal and pointed down at ejection.  Good chute, long time coming down.  Lakebed landing, cracked one fin from the trailing edge corner along the grain.  Should be an easy fix.
