Hi Mark, Nicely done, and welcome to the never ending fun of the GBC! I've been also toying with the idea of using these tracks, and made a module using them as part of the GBC setup we had at Modelma (a modelism fair here in Belgium) Nothing really (...)

More information about your application would be helpful. The first thought that jumps to mind is "Use a more powerful motor. Duh!". So there must be something that I am missing.

I have a gear train that is driven by a very weak input, very small torque. There are some places in the gear train where I have some worm gears driving some 'regualr' gears.
