Well I got my tank and robot arm yesterday.... I broke the tank after about ten seconds. I tried to shoot the gun and the first BB got jammed... So me being me I had to take it apart to fix it. I had to remove everything from the bottom up just to get the gun out. Well After being careful not to break or loose anything I got it apart, holding the remote controlled bb shooter in my hand, looking at the jammed BB. So once again I still had to take more apart. SO I undid the screws on the gun, trying to be careful in case there was a spring... well there was. I had BB gun parts shoot all over. I managed to get it back together and then found one part so I still have to work on it some more.
Good news is that I assembled the robot arm in a few hours and that thing is neat. Now all I have to do is get a 5 channel controller to make it wireless, then attach to the top of my tank, which will be easier without the gun and top turret section.
So now I'm thinking the BB gun is not going to be put back on the tank, if I can get it to work again I might make a booby trap in my room or just make a mounted BB gun somewhere..... hmmm maybe somewhere on my truck
