Hi, i would be interested to start a new topic : low noise props.
Reducing noise is my main interest in this top project. The main problem with this kind of motor is that props are turning fast and are generating quite a bit of noise. There are certainly new props (22’’ or 23’’ fitting OpenPPG) on the market with the increasing drone market, that offers new designs to reduce noise. Sound could also be studied to work in less bothering frequencys (lower frequencys are usuelly better).
Any ideas ?
