This set contains six super detailed, 3D printed 3-inch rockets and rails, as carried bySea Furies and other a/c . The rockets and rails are printed as one piece and the folded metal clips that hold the rocket to the rail are not molded solid, but accurately represent the open gaps in the clips. The separate 60 lb. rocket heads are accurately detailed, and the fins are nice and thin. A simple upgrade over the simplified kit parts. For Airfix, Trumpeter, other kits. CAD By Craig Sargent. (designed to be used with Airfix, Hobbycraft and Trumpeter kits)
