Iceheart,
I am assuming you are using CM 1.1 to install and remove patches to RB (if you are not you really need to!)
In the CM "patches" directory I created a directory labeled "CDT" and a subdirectory under it labeled "Simpatch". I then unzipped all of Charles' planes/parts files into the CDT/Simpatch directory. Next, I used CM to select CDT in the patches window of CM and installed it to RB. All the new skins showed up in RB the next time I flew the sim.
Hopefully this makes sense to you and helps...
