very nice performance from these props, mine were very well balanced and didn't need any additional balancing. they run quiet.The quality seems good (they look solid), but these props have really struggled on NTM 35-48 in a quad configuration. Not perfectly balanced out of the box there is simply too much vibration. If I get these to work a little better will update the review.Very nice props very easy to balance. Look very good.I initially did not receive these with my order, but I contacted Rob from the RCgroups forum and the issues was resolved very promptly.
The propellers are very well balanced and stiff. However 1 of the propellers (I ordered 2 pairs) had a defect joining the one of the blades and the mounting holes. Fortunately, this was not too great an issue as I only required three, but it may be worth ordering a spare pair just to be safe, if you required four.I had apc 10x4.7 props on my aeroquad multirotor.It had pretty good lift with 935kv motors .i put these carbon 11x4.7 props on this bird and what a difference in lift and stability.It's a rocket now!First of all, these are super stiff. Way stiffer than any plastic props I have used. Secondly, I had presumed these would fit a Dji sized hub, but I was mistaken. The 6mm hole steps out strangely to 7.5mm, whereas the Dji size hub requires 8mm. I managed to ream these out to fit OK. They required a fair bit of sanding to balance. Not one on the 6 props I received was even close to a balance. Have not flown these props yet, but looking forward to it.Nach diversen Propellern und Marken, bin ich auf diese umgestiegen, gnstig in der Anschaffung und gute Qualitt, nur das wuchten nicht vergessen!Tried these over the same size gemfans for my 2.4kg x650f quad and straight away noticed how more stable it is due to the props not flexing and are a lot harder to break on those topple over landings. They came pretty close to being balanced out of the packet.
Also noticed they were quieter and descending through prop wash didn't affect them as much. Will be using these from now on.Theses props are magic, I ordered 18 so i would have spares for my HEX build, several months later and approximately 30 crashes with different frames and set ups, not a single prop has broken!
Only issue is that they don't come balanced so expect to spend some time getting it right, once you do, they will never go out, and they won't break, Love them !Very still and strong. Comes with 5mm adapter which fits the NTM 28 series accessory packs.
