This mysterious switch hole I found on my Heng Long Panzer III L, located behind the tracks, I looked it up, and every video I've found on this model had this switch hole switchless. So it seems to serve no purpose other than to let water and mud inside. Which judging by how dirty interior was when I got it secondhand, is probably why it doesn't run, meaning the weeks I spent causally tinkering with the insides was for naught. Which I suspected but still persisted because I am a stubborn man. But aside from the poor way in which I elect to spend my fleeting time on this earth. I've now started to wonder what this thing is actually for, an upgrade perhaps? A scrapped feature that didn't make the cut, but was left in to avoid having the redo the whole mold? One can only wonder. Or perhaps not, because despite my brains insistence of being the most intelligent of mortal men, I know very little about this stuff. So perhaps I've missed something key.
