RAYCorp® 1045 10x4.5 Propellers. 8 Pieces(4 CW, 4 CCW) Black 10-inch Quadcopter or F450 Props + 1 Battery Strap

I bought their pack with the red and black props together and after a few crashes I bought them in the bigger packs. These withstand crashes and bumps better than other props I have used and I have used those grey ones that fly slow and seem tough! These black ones require more balancing than the red ones, but just about 2 inches of tape to make them stay level. The blades track well even under load and that is important on a quadcopter!I'm building a 250 quad and just bought their 5 in props, I wouldn't hesitate to get any of their props after using them for awhile now!Make sure you get prop adapters that are 6mm they center way better than the 5mm ones and the adapter ring! It's worth it to upgrade the adapters if you are doing video with your drone just to get rid of any vibrations.

As described, fast shipping. Will buy from again. Great deal for quadcopter pilots

Exactly as described and shown, work well on my hexacopter. Good price and good quality.

I've bought these and other sizes multiple times from raycorp. each time has been disappointing to say the least. Very frustrating to feel like glass propellers would be better to use than these props. Honestly, I wish I was kidding but really I'm not. Fragile, easily broken, poor quality, cheap, waste of time and money. Don't place them on any expensive aircraft. I had one prop come apart in mid air. Prop had not been used prior to incident. I've tried contacting them and discussing my issues with them several times but no replies.

Let me preface this with a little background... I fly drones both occupationally and recreationally. I purchased these to use on a drone that I built up (550 Class F550 style NAZA hexacopter). The blades need balancing, but that is to be expected. These blades will break mid flight for no reason. Thankfully being a hexacopter, I'm able to maneuver it back to land without crashing in most circumstances. I've had a number of these break midflight for no apparent reason. I use them to test and tune, or in an emergency, but I will not fly with these unless I have to. They're cheap, and yes they work, but they don't last as long as they should. I don't fault any prop for breaking on a crash landing, but it's unacceptable to have props break midair in flight without any warning. If it was a quadcopter, it would have crashed EVERY SINGLE TIME that one has broken on me.I've ordered this item 3 times now, and it seems that it was not just a rare problem. All 3 packages I've had similar performance.

These props look good and feel good but I broke everyone of them when my f450 was taking off and the rear end came back a little caught the ground and the props just snapped off they are not worth it they just break way to easy and they have not sent me any to replace them

These props are some of the best I have used. I put them on my Hunter 500 and immediately noticed a slight performance encrease in punch out, loved it. Get these and see the difference.

The propellors work well in flight. While taxiing one prop touched ground and broke. The props are delicate. They are not glass filled robust and strong.
