This is the ultimate maple seed rocket. It is also the most
difficult to design, and very unsafe to launch if the design
is not correct. Some ideas:
- use the ejection charge to change the weight distribution
- use the ejection charge to change the fin area
There is not a whole lot else you can do, so this is a very
constrained design problem that calls for imagination.
And, as if I haven't said this enough, already, yet...
Unstable powered flight is dangerous to
observers and bystanders, so be extra
cautious launch testing your design.
