I have had this black hawk for quite some time, and recently, it has started to misfire. I initially thought it was the rda shorting, but quickly dismissed that by putting it on a friends mod and checking for shorts. I then checked to see if the battery was the culprit by putting in a fully charged, brand new battery... still had a misfire. after some research, I found out you have to clean your mods from time to time. After I cleaned the contacts and all the threads, it was working at 75% efficiency, but I am still getting a misfire from time to time. The only thing i wasnt able to clean was the top cap, and I believe that is where my problem lies. So my question is: Is there a way to disassemble the top cap so that I can get in there and give it a good cleaning? I can't find anything on the subject matter. Alternatively, could there be something else causing the misfire problem that I am unaware of? Thank you for any feedback.
