Features Include:

  • Two-piece, lightweight assemblies fit all 24mm through 75mm reloadable and single use motors

The motor retainers will need the motor tube to be built overhanging the rear bulkhead.  The retainer glues onto this overhanging tube.  The minimum tube length is as the table below.  Note that this length is a minimum and we recommend at least an additional 2-3mm.
