If you're looking to buy some used Estes BP engines, how much risk are you willing to take? In other words, let's say the seller has several packs of unused C engines. They were likely stored for 10-30 years in an outdoor shed or attic for many of those years and they look perfect. Are those engines still good? I've read about how temperature shifts can cause problems with BP engines, like CATOs.
And if you'd be willing to buy these engines, how much would you pay for each one?
