I purchased these 9.4x5.0 props because I have already tested product ID 098000012-0 (9.4x4.3), which are a little bit more expensive, and wanted to compare. I use them in a tricopter fitting MT2213-935KV motors. This 9.4x5.0 are stiffer than the others and hub threads are better finished, but they demand more amperes. As an example, for 3S-1300mAh, 3S-2200mAh and 3S-4000mAh, they need 0.3, 0.5 and 0.6 more amps respectively, for the same tricopter, with same weight and flying conditions. Not a dramatical difference, and they run as smooth and well as the 9.4x4.3. In mi case, I prefer product ID 098000012-0 for my tricopter.
