I think the idea is to get a servo rated for higher strength than is needed, since then it should never max out, avoiding loud/high pitched motor noise. From what I’ve seen, higher power servos won’t decrease the noise level to what most would wish it to be (near silent), but it will remove some of the very annoying high pitched sounds, and from what others have reported it can remove anywhere from 10 to 20dB of noise.
Could any one fact check me on this? Hope I got every thing right
