In this video, I pit the DAL T5040 tri-blade against my favorite, the KingKong 5040. I also show you how to measure the speed of your copter even if you don't have a radar gun.
Motors on this test are RCX2205/2633kv. ESCs are Littlebee 20A.
I tested these two props because I had them handy, but I hope to do a more extensive test of props and speed, once I can round up a few other interesting props.
