Big problem with Henlongs
I'm having a big problem with my 2 henglongs.
My son, his buddies and I have put a few hours 'stick time' on these things now, we even used the entire box of BB's that come with the tanks that you aren't supposed to use, and even recycled them a few times,(the ones we could find). So far, every function still works perfectly. What am I doing wrong?
