I was really into model rocketry about 10 years ago and recently noticed
that the only thing left to do on a partially built Maxi-Force I have is the
launch lugs and a paint job. So...
Opened up my old "launch box" and it seems I have about 40 Estes motors of
all kinds. These were new in 1991 or 1992 and have been kept in a "cool,
dry place" all these years. A "brand new" pack of Duracell AA's is marked
"Use before Jan 93".
What ae the odds that these motors are still any good? If they're no good,
what is a good way to dispose of them? And, what of the 10-12 packs of
igniters (still sealed in their plastic bags)?
