Required Documents for a EXP Cub?

Hi Guys,
After having to obtain a new registration and airworthiness certificate for my new Cub from the FAA (the originals blew out when I was flying with the doors open due to hot summer weather), I was wondering what other documents MUST be kept in the airplane too?

Along with the airworthiness and registration you have to have a weight and balance, and the operation limitations that was issued when the aircraft was signed off by the Feds.
