I bought a quick build wing kit that had been stored in a barn for a few years. It had a dead mouse laying in the bottom of the crate and some spider webs. Cleaned it all up ok though.
The quick build process uses some kind of special automated tooling for riveting that can malfunction and leave the shop heads very long and improperly formed. I found 1 like this that is down in a location that is not accessible. I didn't notice it on the pre-purchase inspection. I'm going to have to ask the mother ship for guidance.
