what does the positive orange wire on the slip ring power? just got a yuneec referb c23 and the orange wire severed between gimbal connection board and top of slip ring. It seem to still function fully despite the wire being split into and can be repaired with a jumper wire.
c23 question

The following drawing is Attachment 23 (C23-E90 Slip Ring Pinout) in "Way To Fix Drones project".
The red and orange wires are redundant. With the orange wire broken, the red wire is carrying twice it's normal current. BOTH broken ends are at battery voltage, and are a danger for short circuits.
The broken wire should be repaired.

just repaired the wire. I placed a small jumper wire between the ends the wire severed soldered them in. installed heat shrink tube with overlap at both ends. used electrical tape on the other wires to cover area that are prone to chafe and expose wire. reassemble the gimbal and did a dry test on the h520 without props all back to working order. Charging up 8 flight batteries for flight test as soon as they are fully charged up. there is a difference in the st16s display on photo mode between c23 and the e90. video setting match up no difference in the picture displayed in the st16s.

Hi Terrence. If you could please tell me what the difference in the photo menu on the C23 and the E90 cameras?
Cheers.
Mike
the difference is it's blurry on the e90 in picture setting while clear on the c23. just got done with 8 test flights with c23 it held up better than expected. no issues with the repair. stable range of use before rtl kicks in when returning is 2500 ft. at 3000 ft it was stable to that point going out then on return the there where some rtl issues.

Is their a possibility that the focus was knocked out of aliment in a crash? If so it could easily be fixed!

just got done with test run at the location that was giving my e90 fits. c23 had no issues at that area totally usable. I going to have to send the e90 for repairs.

WTFDproject in the diagram, what does the abbreviations PWM and TX stand for? and I take that the VBAT mean vehicle battery?
PWM means "Pulse Width Modulation". It is the signal that controls camera tilt for sure, and possibly camera yaw. Both PWM and Tx must be connected or manual camera tilt and yaw will not work. (Automatic tilt and yaw for stabilization is not affected.)
TX usually means "transmitter", but in this case I suspect it means something more like "transfer". I assume it is communication between camera and drone for such things as firmware updates, maybe recognition codes, and for permissive signals to allow functions (such as pitch and yaw) to work. This is just my "working assumption" based solely on my interpretation of a couple very limited observations. Someone more knowledgeable would have to address it's real purpose.

looking to upgrade the antennas. I am not sure of upgrading the mushroom antenna on the camera or the drone 2.4ghz antenna. doing so might make it more prone for EMI issues. The transmitter Is where I am looking to upgrade the 5.8ghz antenna.
