Today I started to test my tank and it only lasted for 2 minutes. One of the track links break and the tracks split apart. It is because the links are weakened, since I had to remove the metal bars that hold them a really huge amount of times, because of the stupid track slippage issue.
It seems it doesn't matter what I do, this tank never gives me a joyful playtime more then a couple of minutes. I don't know why I'm still doing this. This hobby is all about problems.
