Manna need to get quieter drones. People who live beside their base of operation don't like the noise & disturbance.
It seems pretty quiet already as drones go in the video. Even bigger propellers and lower rpm? Some new tip or blade surface designs. I don't know if they can straight out start copying designs from silent computer case fans and such.
