During the development process for the competition rockets, multiply smaller rockets were constructed to test various design changes and also to gain knowledge of the rocketry hobby. Two rockets the Brian II, the Brian III, the Hilux and the Schmiddty were constructed for this purpose.
In addition, a prototype for the full-scale competition rocket was constructed to test design alterations and provide a proof of concept for the competition rocket.
Finally, the competition rocket ASTRA was constructed and launched to compete in the 2018-19 AURC competition. ASTRA achieves second place in flight performance and third overall in the competition.
