Here are some thrust results for triple-blade propellers. I ordered and gathered as many as I could of available triple-blade props. I used an EMAX RS2205-2300KV motor and 4S LiPo batteries. My thrust stand is not the most accurate device, but for comparing propeller and ESC/motor setups it does an acceptable job. I have recently ordered the RCBenchmark 1520 thrust stand for future tests.
Hope these tests results may be of some interests to you:
