I saved this post from Colin, some time ago. I think this might be what you are looking for.
All placards required are listed in the Advisory Circular and the regs, A/C AFS 600, which is viewable on EAA and AOPA websites. You can find all the details in A/C 20-27E part 11 Identification and registration markings. AOPA site allows a search for A/Cs and Regs. See N64KR at http://KR-Builder.org - Then click on the pics There is a time for building and a time for FLYING and the time for building has expired. Daniel R. Heath - Columbia, SC See you in Mt. Vernon - 2005 - KR Gathering -------Original Message------- I remember an A.C. or something from the FAA that gave good requirements for all of the markings and placards required on an experimental (N numbers, airspeed indicator markings, passenger warning, compass card, etc.). It was something like is listed in FAR 23, but was specific to experimentals. Can someone point me in the correct direction on where to find this.
