These props are poorly designed, they have poor performance. They are not like the DJI counterpart. I compared this with the 10x4.7 CF SF, and 11x5 thin style prop on a SunnySky 2212 980kv - 5A 3s. These required 75pcnt throttle to hover (AUW 1.5kg), while the other props hovered at the normal 50pcnt. The only good thing was that they were easy to balance due to the wide surface. I DO NOT recommend these, unless you have a really light quad or a 4s.
