Mamba F722S with Mamba F50 Pro

[Kitch71]

Does anybody know how to use Mamba F722S with separate ESCs, I have totally mashed my F50 Pro and would like to use separate ones.

You'll need a PDB to power the ESCs and FC.
From there you can splice the signal wires from the ESC to the ones from the original harness, or direct solder them to the signal pads on the edge of the FC.

Thanks for reply I assume I will lose the current reading from motors to esc? Also will I be able to combine the neg signal wires from Esc?
Is it a 12V supply to power the flight board? do you know if there is any wiring diagrams for it?

 

[Kitch71]

sorry I ment current readings from Esc to flight controller

I believe correct, unless the ESC has telemetry, you lose current readings.
You can combine the neg wires, but most just cut them off these days.
The screenshot of the diagram says 6S so the FC will take battery voltage.
Diatone actually has a pretty good site.

Thanks Badfish. really appreciate the advice. Just to clarify that the esc does not need the neg wires?

 

[Launchpad]

I'll just say that I've never had a problem by not using the neg signal wire.
I believe it was more necessary with older tech that has since phased out.

 

[Kitch71]

Ok will see what happens then.
Thanks again for the advice

Yah my understanding is for the smaller quads the distance the signal wire is going having the extra GND is really unnecessary for a big hexacopter I've been working on I added them on as well cause it can't hurt and apparently helps with longer runs to have dedicated GND for the signal just in terms of response time (signals lining up, maybe is better way to put it), Joshua Bardwell (JB) did a video about this... of course he did:

Cheers for that. I have another problem now. I was setting up the drone using the speedy bee app and I seem to have lost connection by switching something off. Problem now is it won't speak to app for me to turn it back on again. I was initially trying to find out why my controller was not communicating at the time. I have 3 lads on one red one white and one green. also when I try to connect using the speed bee app a green led comes on in the corner. Is there any way to reset the controller to factory settings?

UART 4 was designated for bluetooth. If you changed that, you'll have lost communication with the bluetooth chip. You'll need to hook up to a PC and betaflight to get back to the ports tab and use the drop downs to find the function. If that doesn't work, you can reset the board in betaflight too. Just be sure to save settings.

I have it all downloaded to my Mac but It won't seem to connect even though I have downloaded the driver. Lights are flashing and seems to be trying but just won't connect, even tried a new lead.

All working now and flown and its a bit of a handful for a beginner like me. Is there any way of adding any GPS or other to help if this thing get out of control?

Basically want to make sure your failsafes work as expected and are set up properly best way to know is to test. Can test by having it on the bench with props off but everything else normal then try arming throttle up and then power off your transmitter and observe the quads reaction once control signal is lost. Can also try unplugging the receiver from the FC if that is easy enough while giving throttle to see when signal from receiver cuts out vs when signal from transmitter cuts out. For finding it I think leds and or a buzzer are your best bets, can setup motors to beep if idle for X time but independent buzzer with it's own power is ideal (in case of battery ejection). SD card in goggles also helps to have some way to play back last known location before disappearing. GPS can work but assumes clear line of sight to the sky to get good connection and accurate readings and needs power. I'm working to hook one up for larger quad that I want to do autonomous flight but for small acro/race ones I think not worth it for me.
