Not as far as I’m aware, but maybe the diet is a good shout anyway 
That’s an idea. I might need a better capacitor though. The Flywoo GOKU F745 AIO only came with a 25V cap. I was sure it was meant to be 35V though 
Good luck! Let us know how it feels when you get the opportunity. It’s been ages since I last flew. My hands cannot deal with the cold and I lose all dexterity
Well, it ain’t the prettiest but the build is getting there.
Everything is soldered up and appears to be working so far EXCEPT this dang Vifly Finder Mini buzzer! I cannot for the life of me get it to buzz/beep!
I’ve checked:
- The resource mapping is correct (D15),
- The wires aren’t shorted and are soldered to the correct pads (red to 5V, black to ground, yellow to BB-),
- The 5V pad is in fact providing 5V with a multimeter
- The relevant CLI settings are set to: set beeper_inversion = ON; set beeper_od = OFF; set beeper_frequency = 0.
- RX_SET is switched on
I can get the motors to beep so I know the modes/aux is setup correctly. Any suggestions on what the issue might be? I bet it’s something silly I’ve missed.
My RM Boxer occasionally says sensor lost - not sure if that has any relevance.

What flight controller did you go with in the end?
The buzzer needs to be soldered to the flight controllers’ specific buzzer pads. (Not all flight controllers have them) They are normally marked BZ+ and BZ-
So red wire to BZ+ Black wire to any ground pad and the yellow wire to the BZ-
The Flywoo GOKU GN 745 AIO V1.2.
I’ve soldered it to the dedicate buzzer pads just next to the negative battery pad, so the black wire to the ground, yellow to BB- and red to the adjacent 5V pad.
When I plug a battery in a tiny red LED lights up on the buzzer so that’s got to be a good sign!
Should not the buzzer start buzzing when the power is removed. Until the button is pressed ?
Might be the buzzer itself ?
This was my understanding but it hasn’t made a sound. I’m wondering if the built-in battery is dead and maybe stopping the buzzer functioning even when the quad’s battery is connected.
Try turning on the LED Strip toggle switch under the configuration tab. it looks like that board uses a specific buzzer that has LEDs built in.
Also maybe disconnect your O3 Air unit and plug in a battery into the quad and let it sit there powered up for a few minutes to try and get some charge into the buzzers onboard battery.
It’s already on by default.

This is a good shout. Will give it a try tonight/tomorrow.
ON power on - the exact same buzzer I’ve got does a buzz, I think it works as a stand-alone buzzer.
If I remove the power it buzz it buzzes without any interaction with the FC
It will probably need “waking up” from the factory to stop them just randomly beeping on the shelves.
@Spondes Can you take a photo of your Buzzer wiring and post it here?
Not sure if you can make it out very well (please forgive the terrible soldering!).
FYI, the red cable has black electrical tape on the very end. I’m planning to re-solder the buzzer wires over the weekend to shorten them and clean up the joints, I just wanted to see if I could figure out the issue with it first. For what it’s worth, I’ve checked with a multimeter and there is no continuity between the three buzzer cables/pads and there is between the ground and battery negative.
Tried this for about 25 minutes but no luck. I can feel the onboard battery heating up so I assume it is charging.

Yeah, wiring looks ok to me. I’m just not convinced that those pads are providing the signal to the buzzer. Seems odd to me that there is only a BZ- pad. But yeah it could well be a faulty buzzer.
I don’t suppose you’ve got a different flight controller to test it on have you?
See, I’m only guessing but I think before the buzzer starts to work it might need to be woken up by the signal from the flight controller along the BZ- pad once it gets that signal the buzzer becomes armed once armed if it detects voltage drop then it will start beeping. But because it isn’t getting that initial signal from the flight controller it isn’t armed so therefore isn’t beeping when you unplug the power. same thing with the buzzer switch on your radio.
It’s either the buzzer is faulty or the flight controller isn’t sending the beep signal along the BZ- pad to the buzzer.
Wouldnt the signal be pwm from a switch activation on the radio
Yes, if the mode has been setup correctly. But if the BZ- pad isn’t sending that pwm signal to the buzzer then it isn’t going to work. Looking at the wiring diagram the flight controller is expecting a particular buzzer:
I’m wondering if it will only work with that particular buzzer.
Or the buzzer is faulty.
