Choosing the right motor or combination of motors is important for your build. The challenge permits up to 80Ns of total impulse. What you decide to use in total is up to you! We offer tape match and lightning sticks to help you ignite motor clusters if you choose to go down this route. 
3x Estes D motors is maybe a great place to start in a cluster offering 60Ns total impulse. We also stock 18mm Klima D9 motors, although the choice is yoursk, the Estes motors are more readily available in the US, should you make it to the final!
