One question Bob. .What the heck are you doing up at 3:20 in the morning??? Geesh

As for hauling a lot of props around, it would not be necessary if more people gave reviews of of them and how they performed. A lot of "Prop choice" also comes down to a flyers personal preference and flying style. For my 150's I have about $750 worth of props laying around, including the Mej 32-10, Fuchs 33-12, AM 30-12 3-blade, and the the 3W 31.5-14x8 and 31-11 props. They all perform differently and can be used in a discrete "niche" type of flying scenario. I consider the Mej 32-10 a great all around "lets have fun" prop, the Fuchs is a good two-blade choice for pattern style flying, both the 3W props unload and rip really badly over 1/3 throttle, yet they are the best 3-D props in the group and will PUNCH a plane out of a hover, and the AM 3-blade is now my backup for the Biela. As for 100-110cc sized props, Mejzlik 28-10, Mej 28-12, Mejzlik 29-10, Menz 27-10, Menz 28-10, and the 28-10 and 29-10 Biela's. Again, they all do different things and perform quite differently depending on the airframe they are bolted to. I'm sticking with the Mejzlik 28-12 on my BME-110 powered 40% plane, simply because the plane is nothing more than a 28 lbs Fun-fly, and that's the way I fly it most of the time. By bolting on the 29-10 Biela, however, the planes nature changes a lot, and very smooth sequence flying is possible if the rates are turned down.

Not even gonna talk about the silly prop for my 240. . . .
