Mike. what do you think of a BP re-loadable.
I understand that there would be at least 1 initial detriments:
CPSC would not recognize this as a model rocket because of the metal casing; therefore only adults could purchase and use. Ok so Estes makes a product for adult only.
It sems to me that Estes could use its current investemnet in its Mabel technologies:
you just press a propellant grain/delay/smoke train/ejection charge/clay containg cap into a smaller length and diameter paper casing.
Using a metal casing would allow you to burn the BP propellant at much higher chamber pressures resulting in much higher Isp's.
Nozzles could be single use or multi-use perhaps and replaceable.
looking forward to your responses.

what advantages/disadvantages pros/cons do you see to such a product?
