Hey, the Estes single use engines have expiration dates? Can any type of motors expire? My friend gave me a how box full of motors ranging from A's to C's. I'm using the motors for a science fair project. Do you all think the age will effect anything? I test fired one a couple motors today by taping them upside down on a launch rod and igniting them. Now that was fun! Gladly I didn't hurt myself.
