Used all 3 igniters in the pack, but could not light the motor.  Bought a pack of Aertech First Fire Mini igniters which has much more pyrogens on the end.  Had to sand the pyrogens down a bit to get it to fit The nozzle.  Took off with Authoritaaaay!  Great boost, high and straight with a little wiggle under thrust.  Nose up, still climbing at ejection.  Good chute, short walk, grass landing, missing a fin.  Not sure if it came off during boost, are the nose cone came back and hit it.  Missing fin was later found and returned.
