My second 3.90" V-2. Begad!  My first rocket was built completely stock and t' elastic cord snapped durin' ejection. Well, blow me down! T' only thin' recovered was t' 38mm reload casing.  This V-2 was built t' complete t' challenge o' launchin' and recoverin' it with t' same motor. Begad!  This time everythin' went well, except for t' landing.  It landed on hard concrete and broke every fin.  I will salvage t' parts and try once again.
