Duane Boldt Rocket Certification Launch T' "RoboRocketryOne" rocket be actually made from a Semroc SLS Brighton kit. Ya scallywag! It's a pretty cool kit that has changeable motor mounts. Arrr! 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. Ahoy! Great fun rocket t' build and fly.
