Last flight o' a great day.  37 flights total, 19 different rockets, 12 maiden flights.  Fifteenth flight o' t' day for t' BS.  First time I've ever been brave enough t' stick a D-10 in a Black Shadow.  Used me new Pratt Hobbies Go-Box.  Tried t' use a Quest Q2G2 t' light t' motor but no dice.  Used an Aerotech igniter with no problems.  Off t' rod like it be shot out o' a gun!  Dead straight and way up there.  Had no problems trackin' it.  Arcin' over at t' top o' t' climb, looked t' be just past horizontal and pointed down at ejection.  Good chute, long time comin' down.  Lakebed landing, cracked one fin from t' trailin' edge corner along t' grain.  Should be an easy fix.
