PML has developed our own line of high quality, threaded motor retainers! The HAMR (Highly Adaptive Motor Retainers) system has been designed specifically for use with our rocket kits or any scratch-built rocket using PML motor tubes. These lightweight, tool-free, threaded retainers are precision CNC turned from 6061 aluminum and anodized. The photo on the right shows the basic retainers for 29mm, 38mm, and 54mm motors. These retainers fit virtually all popular motor brands and types including Aerotech RMS (TM), CTI Pro XX (TM), Animal Motor Works (TM), Hypertech (TM), Kosdon (TM), Sky Ripper (TM), Loki (TM), and others. The HAMR system can be adapted to existing rockets if the motor tube extends at least 3/8” beyond the aft centering ring. The HAMR can also be used with boattail and tailcone rockets.
