I just said that because our company manufactures a lot of things currently and we have huge reject material bins where parts weren't made right or didn't pass QC and are just scrap metal from that point on.
The other reason is due to my work background in the RC industry; I was once one of the main design engineer's for Composite Craft and I can tell you I saw tons of chassis, towers, you name it, rejected and tossed out for many different reasons.
So don't take any offense to my comment, it's just to guys like myself that came from the R/C industry parts like that hold zero value to us. I remember having about 200 to 300 RC10 graphite chassis in my office at Comp. Craft in a very large box with towers, arms, molded battery holders, Houge parts, etc... things I had inspected that just didn't quite meet our standards for retail sale, but could have been used by someone that couldn't afford a retail part. So I held on to them to try and be a nice guy for others, but I ended up tossing the whole box out when we moved from one facility to a another a few miles away because I didn't want to have them lug it to my new office.
I'm actually happy that it has some value to you!
