Hello, this is a new unit and hasn't been flown outdoors yet

When the fan comes on I can hear the fan but I can also hear a buzzing sound behind the fan is this normal operation for this drone or is there something wrong? If you have an air 3 does it sound like this when the fan comes on or can you only hear the fan air? When you tilt the unit from side to side with the fan going you can hear modulations in the buzzing sound

Thank you

Yeah... It sounds normal...

Thank you for reaching out. Let me confirm this with the relevant team. I will get back to you with an update. Thank you.

Thank you for patiently waiting. I confirmed that this is normal. The noise is issued when the fan in the operating state becomes unbalanced due to the aircraft shaking. This will not affect the cooling of the aircraft. Please rest assured. Have a nice day.

Sounds completely normal to me.

Thank you everyone.

Thats just the cooling fan right?

Yeah. But it seems loud to me. I hear a buzzing sound

I see - perhaps the fan is slightly loose? May be return it for a replacement under warranty if it concerns you.

Mine does the same and now the controller along with dji fly crash!
