This is a 29mm motor retainer to replace the version found in Estes kits. Primary design objective is to reduce drag by better aerodynamical contours. It can be used with Estes 29mm BP, CTI or AT motors. I designed this retainer specifically for use with the Estes Star Orbiter or Vapor (Hobby Lobby) model rocket.
