Little Joe ll for Estes kit #7227

Booster assembly for Mission 004 that used four Algols and two Recruits with ballast weights. This body is to replace the entire assemby of the plastic  wrap steps in the instructions with a new simplified body tube and motor mount assembly. It will accept the kit supplied fins and antennas as per the instructions. It is hollow as folks have different ideas about motor mount configuration, and includes keyed openings to use the kit's supplied  Algol nozzles of which only four of the six are to be used with this booster configuration. Consequently, with some scratchbuild resourcefulness applied, they can also be used as 18 mm mount locations. You can use the kits supplied rings for motor tube mounting but recommend making your own as an option. This printed body is not the same inside diameter as the kit supplied body tube as it is slightly smaller, so account for this on your compass scribing.
