Would I put this thing in an airplane and fly it over the mountains at
night? Not at first - not by a long shot. I'd build it on a trailer so I
could run it in non-noise sensitive areas. I'd take it to air shows to
entertain but mainly I'd just run it on the trailer trying to break it.

How about putting on an airboat, and have fun, while trying to break it.
The chopping at the waves would put some gyroscopic loads on it that would
imitate, of even exceed the types of conditions that it would see on an
airplane, that you could not duplicate on a trailer.

I saw someone did that while developing a system, just recently. I plan to
do just that.

If after a few years I still couldn't break it, then maybe in an airplane.
Ground testing is the expensive part. 2000 hours at 10GPH = 20,000
gallons at $4 each = $80,000. Nobody said it was cheap.

While I agree with the need to thouroughly test a unit, I do question the
need to do 2,000 hours, unless you are going for certification. Running it,
tearing it down occasionally and carefully inspecting (including
magnafluxing) will give you all the information you need for deciding
whether it is going to go the distance, IMHO.
