This flight I borrowed an aerotech single use E15-7W Id heard they were up too three times more powerfull than the estes E9 motor, Id say thats fair.The bullet left the pad so fast no one could get a picture of it, and vanished out of sight, it is a small rocket,.After like 4 minutes or so , some one yelled there it is, landed like 300 yards downrange in a swamp.Returned unharmed though.This is one tough bird.
