All the Locos have basically the same gearbox but the final drive ratios were either 21:1 or 42:1. The difference between the two was that the 21:1 box uses a double helix worm and the 42:1 uses a single helix. j

Would it be possible to change out the worm in the Williams Challenger then? Is that why it's so slow and so loud?

anything available like this?
