Clicking noise from sensors?

[Jerry Guan]

Hey all
I am a total rookie and know little about drones. I know how to fly them and all but I'm new to all the new hardware. I mainly use my P3A for videography

I purchased the P3A last week. Took it out of the box (Yes I read the manual and everything) tested everything and is working. Then I was testing it indoors, and when its on, I can hear this faint clicking noise.. It sounds like a fan hitting something? Not 100% sure though

However when I put my finger over one of the Visual Positioning Sensors, the clicking stops.. Is it normal for the VPS or sensor to click? I read on some P4 forums that it's sonar waves detecting the distance.

Should I get a refund/return or is there no issue?

Thanks guys

Yes, it is normal, both my P3P and Inspire make that sound from VPS module.

You will hear sounds from the VPS. If you have any doubts, please upload a video so we can hear what you're describing.
