Any plans-built "RV equivalents" out there?

I can't imagine even Sonex complaining about an autopilot.


Modifications, even sensible ones, (or even the discussion thereof)
have gotten Sonex builders banned from the company mailing lists, a
declaration of being an "enemy", a revocation of the right to call
their planes Sonexes, threats of physical harm, an end to all builder
support, and omission or removal from the publicized list of
completions. Exceptions are made for such things as seat cushions.
