I asked my local FSDO about it a couple of years ago, when I was considering an RV that was still in phase one. They responded within a few days, saying that they would issue a ferry permit as long as the plane had a few hours on it to be sure there were no major issues. I never had a chance to put it to the test; the builder sold it to another person before I got the OK.

As most of us know, this kind of stuff is unfortunately highly dependent on *your* FSDO, unless you can show them chapter & verse in the regs. With some, even then....
