I have recently started building a Y6 which will have an all up weight of about 3kg. For this I will be looking for some decent (strong/stiff) composite props at a reasonable price.
Recently I came across RCTimer's Carbon reinforced props. Has anyone had any experience with these 12x4.5 Carbon Fiber Nylon props?

Haven't tested them myself yet, but looks promising.
I haven't tried the carbon fiber re-inforced ones, but their epp quad props are absolute garbage. I made the mistake of buying 12 pairs.
Due to the 3kg planned weight, I would go with an APC at a minimum.
