- The ring brace is now fiberglassed, sanded and painted
- The wiring connections to the servos and pressure switches are complete
- The parachute deployment mechanisms are complete
- The fins are complete
- The sustainer is finished
- The flight computers have been attached
- More pressure testing of various components and bottle assemblies.
- Attaching various things like parachutes and the ring brace to the bottles.
- Mounting a camera and altimeter in the booster
- Bunch of little fiddly things
- Full integration testing of the entire system at 20 psi
- Launch abort loop and hook
There are still minor things to finish during the week, but most of the long lead time things are done.
The new ring brace can be seen in the image below (red with white stripes). The red Velcro strips around the bottles and lower section are only temporary at this stage to hold the rocket together as we work on it. It makes it easy to remove bits as needed and put them back.
In the photo below the rocket is still unpainted, but you can see the flight computer compartment on the right, and one of the parachutes on the left.
The new sustainer is a little shorter (about 6 inches) than the photo posted earlier in the month because we decided to put a Robinson coupling in the lowest bottle to generate foam in flight for a longer and more visible burn.
