From your post it sounds like we answered your first question in a response to an email you sent us. As we said in that response, the closest product we carry to your description is probably the Tamiya 70103 Universal Gearbox Kit; you can use the 101:1 gearbox configuration to get an output of 121 RPM.
We do not carry a similar gearbox for the 500 RPM specification, but you might look at the Tamiya 70093 3-Speed Crank-Axle Gearbox Kit which can reach speeds of 723 RPM using the 17:1 gearbox configuration.
You might find this article about the differences between brushed and brushless motors useful. You should also be able to find many other articles with a brief Internet search.
Thank you very much Derrill
