Hi Frank
Enjoy watching you dezing and building as you go can't wate for your next episode, I have one question about the way you want to drive these tracks you have come up with a great idea but chain is not designed to be pushed under power and I belive it will turn better to the right with less power than to the left, hope I am wrong and can't wate to see how it works out, I know you don't give up easy.
Marry Christmas and Happy New Year, God Bless you and everyone round you.
