Motor Retainer 3829mm
3829mm Motor Retainer
Both the 3829mm and 38mm motor retainers have the same mounting hole arrangement which allows both retainers to be used interchangeably on the same rocket - i.e. use the 38mm retainer when using 38mm motors, use a 29/38 motor adapter and 3829mm retainer when using 29mm motors.
Threaded inserts allow retainer to be added after model is built.
Note: This retainer requires a rocket with an aft centering ring to mount the threaded inserts. The body tube should be at least 2.5" ID to clear the retainer.
