Great flight on one of the new AT single use Metalstorm motors.  Based on recent results with AT single use motor ejectioon charges not having enough Ooomph, I pulled off the ejection well cap and added another 0.2g to the charge.   Burned one igniter without success, motor lit fine on the second one.  Fast and loud off the pad, nice straight boost.  Arcing over at the top of the climb, early on the ejection.  Good chute, moderate drift, lakebed landing.  Small tear in the lip of the body tube, most likely from the early ejection.  I don't think the delay was short, it just needed a little more than 7 seconds for this rocket.
