My second 3.90" V-2.  My first rocket was built completely stock and the elastic cord snapped during ejection. The only thing recovered was the 38mm reload casing.  This V-2 was built to complete the challenge of launching and recovering it with the same motor.  This time everything went well, except for the landing.  It landed on hard concrete and broke every fin.  I will salvage the parts and try once again.
