I have been thinking about track pads again as I dare to do.
I have a set of the mato rubber chevron tracks that came off the mato 76 M4a1 RTR tank. They are the same width as the metal track pad of the mato metal tracks but the inside of them is hollow, kinda funky. I was thinking of finding a 3d printer that can copy one pad and print them, then I could make a jig and drill them out and swap them out on my metal track set. Yes this is a ton of work, but it would make the tank more accurate and it would look cool, and might be fun too....
