Ok, my cousin took his blaster to a friends and it stoped firing. Well he left it there for a month, and when he went back it started. So, he put it in gear but then it went in reverse. We all know blasters don't have a reverse. So we're wondering what the heck is going on with it. It'll wind out and go into all 6 gears real good, it just goes backwards though. What is the problem and how am I going to fix this?
