I have the ETTI 200A one which looks like the first link you posted. Please look at the attached picture
. All I know about them is that they are sold as a kit and whoever assebles them can add the MOSFET of choice and 3 ot 4 capacitor on each power board. They have an airplane, helicopter and a boat model. I was trying to get an answer if the places that do have them can do a car model, but no luck yet.
