CU L8R was the first rocket developed by CU InSpace. Painted a vibrant Canadian red, this rocket paved the way for Carleton's continued competition in international rocketry competitions.

CU L8R was designed to compete in the Spaceport America Cup 10,000 ft commercial off the shelf (COTS) solid motor category with an Aerotech M-1419 motor. The airframe consisted of phenolic tubes with internal aircraft-grade plywood ribs and stringers to increase the structural properties of the airframe.
