A small hole in the side is provided to allow
battery charging, and to start the payload. The
heat generated during lauch causes the a blow-torch
like stream of air through this hole. Care needs
to be taken when placing critical payload components
near this hole. |

An explosive charge pushes a piston at the bottom
to eject the entire contents of the dart at peak
altitude. The explosive charge is on a 2 minute timer
fuse ignited just before launch. The explosive charge
is part of the tail fin assembly which screws into
the bottom of the dart. |

The payload and parachute are held between two half cylinders
called staves. Here the staves are shown partly
extended out of the tube. On ejection, the staves
are radiply expelled from the tube and split
apart due to the rapid spinning motion of the dart,
releasing the payload and parachute. |
