This is one of many rockets I have built and flown. this is a small one and a scale model I built of the nike hercules . It flys on a cluster of 4) Estes D12 motors. I'm into high powered rocketry and am level 1 certified. I have my level 2 rocket ready just waiting to fly. I have also worked on level 3 rockets just havent had the time to certify. But in the end I still enjoy building and flying the small ones just as much.
