Thank you, great news! I’ve had this radio for about a week, simply incredible. Blown away by the fit and finish and how easy it is to set up and use.

Are you trying to bind two receivers to the same model?

edit: sorry you figured it out before my response.

Don't forget, digital servos are powered all the time, moving or not. So, they will make noise, hum or chatter when not moving or even under very slight load. Analog only uses power when commanded to move. Of course if it seems excessive, its always worth checking your settings to make sure you have the right servo type selected. If an analog servo sounds like that, its usually bad, voltage too high, or type is wrong. But digital can be noisy like that.

the noise is generally dependent on the motors used. Brushless servos are super quiet compared to Coreless motor servos. they also center faster and more accurately.

someone had the following error on NB4?
Resources error! Please update the transmiter firmware.
I can not do anything, it does not go from there.
I tried to update but it does not detect it.

have heard about people having the issue but I dont remember ever seeing a fix posted about it. Try to Contact Flysky support. If I hear anything I will post here.

I contacted Flysky with no luck, they ask me for a non-existent QR code on my transmitter and claim that without it they cannot help me, very disappointed with the brand

uhhh, the QR code is on the help page of the system menu, not sure how you would access that if the radio wont boot. Maybe best just to say it wont turn on.

there's mine. I have no idea how going to a sketchy URL will help them, but that's what the QR says.

THe Tech support is actually pretty good. Keep in mind the translation sometimes gets messed up. Try and reach out to them again. and make it perfectly clear that you cannot boot up the Transmitter to retrieve the QR code. sometimes sending a vdeo clip helps as well.

Ok I got some insight. It appears that if your firmware was very old and you try to update straight to the newest version you get this error.
what version did you have originally?

try to install .79 or .83 or something. And see if it updates? If it does then try the .93 update again.

Curious if that worked?

Do you guys know how to update micro recievers to be able to bind it with the latest firmware?

There is a QR code sticker on mine:
