Noisy band(s) - what gives?

[zytra]

Hey,

I wasn't sure where to post this on forums to get some feedback on a noisy frequency that is constant throughout the throttle range. Something motor related would IMO give noise at increasing frequency (as the throttle increase), but not here.

I've installed another FC with the same results (different model, different electrical source as well). I'll swap out ESC's and motors next but I thought I'd ask if this is something anyone has an explanation for.

thanks!
Cheers

I’ve noticed this on one of my quads as well. I think it might be a resonating in the frame, but not sure.
