Ok. So researching the available drones and addressing noise is job one. No doubt the smaller the drone, the noisier. Likewise, the cheaper ones will probably have more noise. I was hoping since everything is DC, noise might not be an issue. But clearly it is a key consideration. Thanks Nizar. Are there fixes?
