Dude, I have personally dealt with OS in the past for warranty work. However your does not fall under warranty. But I can say that OS is very professional and easy to work with. I think your best bet is to call them derectly, or email them about your situation and concerns. You can try this number...217-398-0007. I don't have their email, however I have a web address...
www.hobbyservices.com. Maybe take a look there and they might have a FAQ area or email. They will treat your right bro. Just let them know what is up. Good Luck bro!
