I wasn't sure what to expect from this rocket, but if I had thought about it I would have put a C11 in instead of a D12.  This is a very light rocket and it really screams on a D12!  Almost out of sight flight.  Wish I had put an altimiter in!  Fortunately we had almost no wind and it didn't go too far from the launch site.  Hit a barbed wire fence on the way down and crunched one fin a little but nothing to be concerned with.
