I have heard that 1 blade props are more efficient than their two blade counterparts which is all very believable, but how much more efficient? I was running a 9x5 MA on a 25 FX, I think that it was running around 13500 ( i havent tached it for a while) I made a one blader from an APC 10x5 and that was swinging at 14200.
anyway, it makes sense that for racing props spinng at 28k single blade props would make quite a difference, but what about normal engines running in the mid teens? is there much to be gained from one bladers for the average flyer? Am i wasting my time making these carbon fiber oddities?
