14 members of COBRA successfully tested our largest custom rocket motor to date on November 3, 2018 at the Pawnee National Grassland under the authorization of Northern Colorado Rocketry. The 114 mm (4 inch) diameter motor, which was mounted on COBRA's custom-designed test stand, developed over 1 kN of peak thrust and burned for approximately five seconds.
