Hi Dave, I have been flying behind one for about 450 hours. My application is probably unique so I submit that you may want to take my report with a grain of salt.
My prop is small diameter 54" and high rpm (cruise in the 4300 rpm range). I had my blades profiled for high rpm use by Gary Hunter (former Pushy Galore crew chief). The prop works. However; I believe that it is far from optimal/efficient. With that in mind, I would not be scared to use the prop but I would not have high expectations for performance. The ground adjustability is sometimes worth that price. Plan to spend a bunch of time initially getting it setup correctly (proper pitch, all blades at the same pitch, tracking, etc...). BTW; I have heard it said quite a number of times that carbon fiber props should not be used on VW engines. I do not know if this applies to Revmasters and/or if anyone has actually studied this problem or it is just an old wives tale (I suspect the latter). I do not wish to spread rumors, neither do I care to read you had a crank break and destroyed your plane. Steve Bennett can probably clear this up in short order.

This would be mated to a Revmaster 2100. Thanks Dave.
