I just finished putting together a step by step guide to upgrade your Nano CP X to brushless. Using the Dozuki software available for free on MakeProjects.com. It’s the same software that iFixIt uses, which allows you to generate a PDF, or XML of the guide at anytime. It’s also a living document, so anybody can add to it to improve it.

Best of all, you can download the Dozuki app for the iPhone or iPad, and it’s formatted like a manual. So one can be at the workbench and have the iPad mounted on the wall to refer to as you’re modding.

Update 2013-03-09:
Well, that’s unfortunately. MakeProject is going through a makeover. So the guide is down. Doesn’t seem like they will be using Dozuki’s platform so it’s uncertain what the guide will look like once it’s ported over to their new system. Will update once I get more info.
