I agree. The only other harness that fit would not let the quad arm.... odd

The paperwork that it comes with lists the missing wire telemetry and the instructions say to use UART 6 for telemetry. Should I move the receiver wire to that UART? Maybe that’s the issue ?

I just noticed something that looks odd on the wiring harness between your FC and ESC. The order of the wiring in the connector of the FC from bottom to top is 5V (red), GND (black), ESC current (white) then the 4 motor signal wires, but on the ESC the order of the wires appear to be 5V (red), ESC current (white), GND (black) then the 4 motor signal wires. So there is a mismatch.

Have you re-ordered the wires on the ESC connector because the photos you posted of all the harnesses (HERE) don't have show any where a white wire goes from a pin next to the red and black wires on one end to a pin between the black and red wires on the other end.




Below are the pinouts of the Hobbywing  XRotor F7 FC and the XRotor Micro 40A ESC. You can see that the same order of VBAT/VCC, GND, CRT, TELEMETRY then the 4 motor signal wires is used on BOTH boards. So why do you seemingly have the white CRT wire from the FC connected to the GND pin of the ESC and the black GND wire from the RC connected to the CRT pin on the ESC connector of yours?

I haven’t messed with any of the wires or pins but this does explain why I’m having an issue with my mah used in the OSD. The wiring harness must have been put together on a Friday right before they closed for the weekend lol

I swapped the ground cable and the white CRT cable on the harness like this.

now it just beeps like somethings wrong?

*edit*
Wait a second... check this picture out.

I think the esc your listing is the 40 amp and not the 60 amp. It’s definitely rolled in the directions in the manual too. I swapped it back and it works but no mah used.

OK, looking at the layout of the visible parts of the ESC on your photo I thought you had the 40A version.

According to the manual, the 60A version of the Hobbywing XRotor ESC has a slightly different pin layout, so your original wiring with the white CRT wire between the BAT and GND wires on the ESC end of the harness is/was actually correct.

Instead of mah used have you tried checking to see if Average Volt Per Cell works?

Just to see if it can get any sort of reading from the battery.

Yes I get the battery volts per cell in the OSD. I usually use the mah used like a gas tank meter. If I fly an 1100 or 1300 battery I know when to end the flight but the volts per cell is the same idea. I fly 6s and I’m always conservative trying to land at 3.7 volts a cell. Thank you all for trying to help me figure this out. Possibly this is a betaflight issue.

Thank you for always helping me and the other people SnowLeopardFPV. Your an amazing help to so many people in this hobby.

If the wiring is correct asper the FC / ESC pinouts then I agree that it has to either be an issue with Betaflight target for the Hobbywing XRotor F7 FC, or a hardware defect somewhere on either the FC or the ESC. I would also check continuity on the CRT connection by using a multimeter to test the end-to-end connection from the back of the pin on the socket of the FC to the back of the pin on the socket of the ESC so you know that the harness connector pins is making a decent connection inside the FC and ESC sockets.

It would be good to be able to confirm if anyone else is having this same issue with the same FC / ESC stack combination. I know other people on here who are running one or the other but I can't remember if anyone is running the exact same FC/ESC stack setup.

You could also potentially raise an issue on GitHub at the link below and see if anyone comes back with an answer. I don't see any other issues of the same having already been raised so either no-one else is getting the same issue or no-one has reported it yet.
