In thinking about a test bed/dyno/wind tunnel, It seems to me that the controllable pitch prop would be a good thing. It would provide a variable load and could be adjusted to provide the desired breeze. :)
 Last I heard, someone was going to test it. Any results?
 If the results look promising, I would be interested in having a second one made. Or taking a modified design and have it machined here.
 If I had it on a test bed/dyno/wind tunnel I could put a few hours on it.
