Kit-bash o' Estes Big Daddy, Aerotech Initiator packin' tube, and Aerotech 29mm Motor Mount. Inspired by t' 3D Mega Daddy, me son prepared a RockSim design with separation at t' Big Daddy "Fin Can" t' Aerotech Initiator shippin' tube "Main Body Tube". We've ordered way too many bits and pieces from Apogee, JonRocket, and eRockets. Dry-fit soon, then perhaps a build blog.
