I purchased this prop to test on the GForce MR2814-KV800 from Value Hobby. Testing with a very accurate shunt, 3S battery, gave me 29 Amps at full throttle. There was no heating of motor or 30A esc noted after a 1 min run at full throttle. This prop seems to be a good top end for this motor. My only issue is I wanted to use it for multicopters but I cannot find it in a pusher prop configuration. Hopefully Towerpro will step up and produce one in a pusher format.
