RCGEEK Carbon Fiber Propellers 8331 Low Noise Blades Foldable Quiet Props Quick Release Replacement for DJI Mavic Pro Platinum Mavic Pro Propellers, 2 Pairs

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!

Preamble: Came off of flying R/C Extra 300/Edge scale model in San Diego and Lost Wages for 30 years. It's a dying hobby/sport due to fuel cost and field restrictions... blah blah.I gotta fly something...so I plunged head first into a dinky Holy Stone HS720 Foldable GPS Drone and bore the you know what outta me in <72 hours. After lightening situation-room research (I'm fast) I immediately new the Mavic air II was getting me closer to my fix. The OEM (great!) props had to go and the carbon new replacement fibers are in but aren't perfect like my $100 carbons for my Extra 300. But ask yourself this. You got a ma(v)gic bullet so go for it. I immediately felt more acrobatic...like me good old days.Long story, this was leverage for my good wife to "allow" me to venture further like a good enterprising Scorpio pilot.-> I just purposely lost my mind and purchased a Walkera F210 3D Edition 2.4GHz 120 Degree HD Camera F3 3D Knocking Down The Wall Racing Drone RTF w/Remote and I'm gonna be the bat from hell. Yeah Baby!!! :)Fly Safe!Stay tuned folks.

I'm usually not a fan of writing reviews, but I can't pass on this one. I bought two sets of these rotors to test based on the fact that they're carbon fiber and therefore should be stronger that your normal rotor. I got more than I bargained for. I was screwing around with my pro in my living room and inadvertently did a full speed climb right into the ceiling (rookie mistake!) and made full contact with all four rotors! After I landed it I did a full inspection of the rotors and much to my surprise, there was no damage at all. NONE! Needless to say, I was impressed. After that I took it outside to put my mavic through its paces and was very impressed at it's performance. These rotors seem to be more responsive as well as slightly quieter. After I examined them a bit closer I understood where the additional responsiveness came from. If you hold one of these rotors next to a Mavic rotor you'll see that the blades are wider than the Mavic's and therefore have more lifting surface. Now I'm no engineer, but I believe having that additional lifting surface would cause a decrease in the amount of power required to lift the drone which would help decrease battery drain. Those are just my initial observations, but if I'm correct, I believe I'll be sticking with these rotors for awhile or until I find out I'm wrong. Good job!

I like the originals

I'm not sure these are any quieter than the original DJI props, but they are stiffer and may offer some marginal performance advantages. They do, however, polish up nicely and they look great, especially on my neon orange wrapped Mavic Platinum. They're a little stiff at their joints to begin with, so it's a good idea to unfold them into the open position before arming the drone.I have also used these props on a plain Mavic Pro, not Platinum, and they caused a vibration problem. The ESCs can be tuned to suit them by taking 15% off the front and moving it to the back, or maybe it's the other way around. Check on-linefor how to tune the ESC if you've got a plain Pro. They are noticeably quieter than the stock Pro props without the little upswept tips.

Broke when I put the propellers on. I've been waiting for two weeks for a replacement and the tracking won't update so I'm not sure if the package has been lost.Won't order from them again.

I absolutely love the look of these blades. High quality with no hit to your flying performance whatsoever. Little pricier than the regular blades but they feel more durable. Won't know until I hit something or crash my drone I guess. Either way, these are good quality blades.

Look awesome , worth the wait . They weigh exactly the same as stock blades, they were a little tight where they are rivited , don't think they would unfold , just worked them until they extended. No problems.

Packed well and arrived on time. The props are extremely durable and well built. Carbon fiber is amazing. Haven't used it on my mavic yet but I'm sure it will work better than the factory props.

One of my favourite prop upgrades for my drone. Crashed only one prop broke.

Haven't tried them yet but they look OK. These are basic essentials. Amazon should quality check props.
