Guys, I think we're dealing with a slight translation issue here. If you read his post a little more carefully I think you'll see he's talking about transmissions.

To Tottanka,

I'm assuming you're talking about the transmissions that came in the kit this year. If you're contemplating building your own transmissions to reduce the speed of your CIM motors or other motors, this is perfectly legal. I would, however, caution you that it can be a very finicky task. Just make sure that you add a little more distance between the gears than just the pitch diameters, as your machining isn't likely to be perfect and it's far better to have a transmission with a little backlash than a transmission with a lot of binding.
