So any news about the low-noise propellers for the spark?

[QUOTE="cozzykim, post: 57412, member: 6499"] The point is that turbulence also = noise, so that any modification to reduce turbulence will not only reduce drag but also noise. Reshaping the tips of a standard set of blades by removing material so that they are like the Mavic Platinum blades could thus theoretically be done without losing efficiency if it reduced drag and noise. I don't think you could do it by hand though, as the tolerances to avoid vibration are so small at high RPM, it would have to be done with an accurate jig and maybe laser cutting? We have a possible* template in the Platinum props. *Though other differences in the blade may make a direct copy of the Platinum tip shape useless. Is anyone here an aerodynamics expert? I guess that this would be pretty easy for DJI, and I'd be buying a few sets of low noise blades like a shot. [/QUOTE]
