Has anyone noticed the plastic to plastic vibration noise with the H while hovering or descending? It was irritating to me -- sounded horrible. No issues with flight, but just bothered me that there was enough vibration to be heard over the props. I often wondered what that vibration was doing to the components and wished it wasn't there.
I don't recommend anyone doing this, but I've found a solution that I applied to what I'm now calling my test H. My test H was completely totaled with 3 broken arms, broken air frame (the hex part that all the arms and controller board connect to), broken legs, upper and lower shells, camera connection wires, etc etc. It was a mess. I rebuilt it completely and it's fine now.
Here is what I learned as the cause of that irritating vibration. It's the upper and lower shell assembly and how they "mate" to one other. You got it -- plastic to plastic on the posts and around the outer shell casing. Some posts mate upper and lower shells alone and some posts include the air-frame sandwiched between them. Since I didn't know if the H would ever fly again and if it did, it would only be for test purposes, I decided to apply a remedy. And it worked.
Using only my finger, I applied a very thin film of black silicone on all plastic to plastic mating points and perimeter edges during my final re-assembly. Let it dry overnight, then re-assembled. I think the perimeter edges -- do to their "fit" - were the worst areas of potential vibration. The film had to be very thin as to not prevent the mating of these edges.
Amazingly, all I hear now are the props and motors in any direction (up down sideways etc). What an amazing difference. And yes by the way, complete success with the re-build.
Thought I'd share.
