- Yup, we used a manufactured motor the last time around, and we
- are most likely doing the same thing now. I don't have the specs
- of the different type of engines with me, all I recall of it is that
- it was solid-fuel ("propergol" in French; don't know if it's a
- direct translation of not), and came out to around $1000 apiece.
- It was donated to us by the French Space Agency. How could we
- refuse?
-
- We didn't experiment with the staging concept. First we want to
- build a reliable parachute ejection system as well as a dependant,
- expandable inboard computer system. Once that is done, we will
- most likely include funkier scientific experiments, staging and
- picture-taking.
