I know from "Tube" that many tests and comparisons have been done on these Master Airscrews and compared them to original DJI OEM propellers, but here is mine Version. I used a somewhat unscientific method to compare them, but it's important to me. I mounted my phone's camera on a tripod and marked the set distance (I think it was 7ft, but that doesn't matter). I then tried each set of props at a height of 1 meter and then juxtaposed the video clips for auditory comparison. (see video) There is an obvious difference in sound. The Master Airscrew props have a significantly lower pitch than the DJI props and overall sound a bit quieter to my ears, but I didn't have a dB meter on them. for confirmation. I also didn't fly them to compare speed or flight times. Only sound and volume that were good enough for me. Definitely a nicer, deeper (or maybe softer) tone. I also like the glossy black look (they come in several different colors). Watch the video and draw your own conclusions, but I'm hooked!
