Prop noise when releasing throttle
#1
Alright so I'm hearing a sort of rattling sound when I release the throttle after a quick burst. There's no indication of this in the controls when flying. I only noticed it in the Gopro footage. Think this is anything to be concerned about? 

The video is below and here's my build thread for the parts list: https://intofpv.com/t-i-ve-decided-to-bu...th-machine





Thanks!!

Edit: Most noticeable at the 0:30 mark

Just flew again to test it... No not really metallic sounding. I have only one battery strap that I'm absolutely positive is not making contact with a prop, but if you could imagine a prop barely making contact with a battery strap, that's about how it sounds when I am close enough to hear.

Sounds like something rattling against the mic to me

Update: another video. Looks like it is only when I pitch or roll, not when I throttle up. definitely not something on the mic, props not making contact with anything.

I FIGURED IT OUT!!!

When I built the quad, I used the SupaFly preset tune in Betaflight. When selecting this preset, there's an option to select a receiver and I selected ELRS. Wellllllll, it clearly states that its ELRS at 500hz, however my Boxer is set to 1000hz. This excess non-audible-noise apparently must cause the audible noise I was hearing. 

Set my radio to 500hz and not a sound!
