I know that many Warbirds (including this one) are under the
Experimental category as "Racing and Exhibition" aircraft. FAA order
8130.27 spells out the limitations for 4 groups of aircraft that
encompass just about any type of warbird that I can think of (except
ones that are certified as standard category planes).

What I'm still not entirely clear on is how I get the letter from the
FAA that is based on 8130.27, spelling out the limitations. I'm
assuming this is much easier on a plane that has already been operated
in the US by 2 prior owners (the flight test requirements should be
already met I assume).

I'm still reading through all of the documentation I can find, but if
someone has gone through this recently and can spell out the steps they
took to ensure that they were legal, I'd appreciate it. I'll be calling
the local FSDO on Monday morning but I'd like to have some idea what
I'm talking to them about.

Thanks,
Eric
