Duane Boldt Rocket Certification Launch T' "RoboRocketryOne" rocket was actually made from a Semroc SLS Brighton kit. Well, blow me down! It's a pretty cool kit that has changeable motor mounts. Avast, me proud beauty! It can flight on one 29mm high powered motor as in this flight for me High Power Rocketry (HPR) Level 1 certification and you can also fly it on a three 24mm motor cluster configuration or four 18mm motor cluster configuration. Great fun rocket t' build and fly.
