I’d like to see Estes follow the Disney movie example . Bring a few out of the vault every year for limited time and reproduce all the old lineup of rockets. This last year I built the current bring backs,Patriot,red max ,Nike X ,multiroc , Saturn 1B. So just keep the oldies coming!

Do cans of R-12 have a shelf life? Just wondering.

As long as the cans stay sealed, there should be no finite "shelf life" for R-12

The only example of leakage from such cans that I know of involved/involves the Canadian-made LOGIX (and also made by the Tandy Corporation) Aeronautical Lab Kit. They came/come (some unused ones are still around) a small can of helium (the can looked/looks like one of those used for aerosol shaving cream), for the balloons used in the section on aerostatic flight. The lab's manual itself warns to not leave the can unused for long after its plastic button-valve is first pressed, because the helium will steadily leak out once that is done. (The very small size of the helium atom makes this possible, which is why hydrogen- and helium-filled weather balloons, pleasure Charliere balloons [gas balloons, as opposed to Montgolfiere balloons--hot-air balloons--hydrogen is often used in Charliere balloons in Europe because it's much cheaper than helium; all components are electrically connected to prevent static sparks], and airships take off soon after inflation is complete, and require extensive use of envelope and valve sealing compounds on the fabric ones.)
