Buzzing noise from AR600 RX when connected

[boliao7378]

Hi Guys,

I bought this Parkzone P-47D which is a BNF version, thus it comes with AR600 Spektrum RX. After binding them, the RX will give this buzzing sound. I've tried changing to another RX and still getting the same buzzing sound.

Can I know if it's normal or I've done something wrong. And if wrong, what is it?

Thanks and cheers for now.

Rx yet.

Ok guys, thanks. So if its coming from servo, its ok right? the buzzing sound won't stop unless I pull the battery out.
