- Includes Pod Set for Estes Universal Astrocam, designed for approximate size, weight, and aerodynamic effect. > simply delete the pod set if you don't want it.

- Plywood centering rings were used without the stock vent holes. > 3/6" vent holes were place near the top of the booster instead.

- There is no engine block on the booster. > place a 3/16" strip of masking tape around the circumference of the motor at the boottom instead.

- There is no motor retention. > tape the motor in place using a 3/4" long strip of 1/2" masking tape. > 3/16" of the bottom of the 24 mm MMT was left unpainted for this reason.
