Paul,
If memory serves me, and sometimes it doesn't, I remember seeing someone
took a Cessna and replaced the engine with a Mazda rotary. They then
registered it as experimental.

Do you, or anyone have info on this?

The FAA frowns on that big time. Only if you plan on getting an STC
and first you have to certify the engine. That means you make all the
parts and you have a paper trail from the iron mine to the air.

NASA did it but that was NASA.

You can make a fiberglass mold of a Cessna fuse and use Cessna wings and
tail.

That is OK. It is then a experimental aircraft.

I'll have to disagree with you Paul.  The FAA will not certify an
airplane assembled from spare parts as an experimental armature built.
Time was when that would work, but no more.  Even if the wing is toast
and you totally rebuild it they still will not buy it.

Not spare parts from the same airplane. Parts from different airplanes. If that
were not true you would not be able to use some of  the parts found on some certified
airplanes.

Lets take a Bellanca Viking for example. Lets assume the wood wing
is shot. If you make a new wing out of carbon fiber then it becomes
an experimental airplane. Arguably you have built 50% of the new
experimental airplane.

Lots of people have built experimental airplanes using wings from
certified airplanes. Quite common in the cub world.
Only 50% of the airplane needs to be built by you.

 Cessna put a rotary engine on a Cardinal decades ago. I have pictures of it.
They also put forward swept wings on a Cardinal.......but that was Cessna, not any individuals.

Well send me the damn pictures :)
Yes aviation corporations can get away with stuff like that.
