There are certain things that need to be recorded in "aircraft records". There is no specific definition of "aircraft records" anywhere in FAA documentation. It's really up to you how you want to keep track of maintenance history on your plane.
The most common way, of course, is logbooks for airframe, engine, and prop. However, that is not set in stone. I've seen all kinds of variations on the theme, including electronic records nowadays. You will be required to have someplace to make entries for condition inspections and other required items, but how you do it is up to you.
The EAA logbooks are fine, and in fact the airframe logbook is very handy because it has the initial condition inspection already printed in it, along with a space for the FAA inspector to put his/her entry approving the aircraft. Other than that, it's just a normal logbook.
So it's really up to you. If your aircraft is not yet certificated, you might want to ask your friendly DAR or FAA inspector what he or she would like to see and follow that recommendation. But the world is your oyster, so do what works best for you!
