RCGEEKCompatible DJI Mavic 2 Pro/Zoom Carbon Fiber Propellers 8743 Quiet Props 3 Blades Strong Pulling Force Quick-Release Foldable

I am amending this review to take up the topic of the bad reviews people are giving relating to the use of screws to attach the blades. If you look on the opposite side of the screws, you will find they used brass inserts, and those brass inserts have been tapped slightly undersized to hold the screws VERY TIGHT! I broke several loose with considerable force using the ball end of a 1/16" allen wrench, and even once broken loose and removed half-way out, the screws are still too tight to back out by themselves. If you are really that paranoid about it, remove them and use red lock-tite to secure them.I also want to address the affect these might have on your battery level/flying time. I tested battery run time by going up to 300 feet AGL and just running full stick in Position mode in a big 1-mile radius over farm fields until I got a low battery warning, then returned to home. I repeated this with three batteries, then changed the props back to the stock ones and did the same for the fourth battery. All four batteries were drained down to the same percentage give or take 1 or 2%, and all four flight times were 21 minutes - exactly. So I believe if you were to do a hover test, you might actually have a little longer battery life because physics says you will get a lot more lift out of three blades vs two. I will conduct a hover test when I have the time.Now back to my original review post:They would arrive on a rainy day, wouldn't you know. I'm an old Air Force avionics technician from the 70's, and I know all too well what adding a prop can do for you. I have been dying to try these all week, waiting for their arrival.The first thing I have to comment on is these props sure look like they could use some form of final polishing as they look scratched and marred up as you can see in the pictures. Nothing wipes off, so it's in the finish. I thought they would be all shiny and have that carbon fiber look we all know. They have more of a dull, used appearance.Without getting into breaking out the calipers and whatnot for getting exact measurements, besides the fact that each has an additional blade, I can say the pitch on these blades is greater than the stock props as well. Now I'm really chomping at the bit to try them out. I will update this review after I have had a chance to run down three batteries so I can do a fair comparison of any changes in flight time on a fully charged battery vs with the stock props on the Mavic 2 Pro.UPDATE 01-18-2019: WOW!! Do these things fly! The next chance I get to measure sound levels, I will do so. They seem just slightly louder than stock, but don't hold me to that. I ran these hard with three fully charged batteries, then put the stock props back on for the fourth battery, and I got the same amount of flight time on all four batteries. They definitely do not cut your battery time down any. Response to stick controls is insane, so if you have an application where you need to make very small finite movements, put the stock props back on. I also gave them an obstruction test to see if they outflew the sensors ability to stop in time, and it really slammed on the brakes in a heartbeat. Regardless of which set of props you have installed, the software controls the top speed. So they do accelerate the drone faster, and they stop a lot faster, but they will not increase the speed of your drone. I do love these props!! But I will try to find a warmer day to check out the difference in noise levels next time out. Until then, these are AWESOME!!UPDATE 01-21-2019: Ordered another set!

props are slightly bigger then factory props causing the rear to hit the housing of the drone! after measuring them all none of the props are a consistent size!!! DO NOT USE !!! just stick with the factory props!! I'd leave Zero stars but had to click one to leave a review!!! AGAIN DON'T USE!!!!

I think be returning this. I own Both Mavic two pro and Mavic to zoom and I would not use this on either one again it in fear that it’s instability would cause damage to my nice very costly investment in a DJI drone which you are of superb quality in light years ahead of any competition that I have experienced. Maybe I’ll try some of the LED programmable’s instead because Dji designed the two blades system for a reason and without possibly modification to software to accommodate the third blade which are very likely to stick and become one and a half to 2 1/2 blade units I wouldn’t do it it’s going back!

These tri-blades are each 10 grams while the OEM two-bladed ones are 8 grams each. They are just as balanced as the original DJI props straight from the factory. Therefore, no abnormal vibration or noise. These props actually run at 40~60 RPMs lower then the stock props for the same speed & thrust which makes them slightly quieter and gives 2~3 minutes of extra flight time from 99% state of charge from the battery. I’m giving it 4 stars because of the finishing quality which is mediocre. Otherwise, I found these props to be better then OEM props in every way in all my testings. Worth the price.

I'm a beginner so take everything I say with a grain of salt. I bought these Carbon fiber blades expecting it to quiet the Drones propeller wash noise and instead I don't see any difference and with the extra blade it is hard to put the Drone away in my case without removing them. the extra blade per set seems to be draining my battery much faster. All that being said they do look like they could take a beating. last photo is back to stock propellers and Drone fits in case nicely. By the way propellers will not close anymore then shown.
