THE New Go-FOC DV4s

Aren’t there 3 versions of that ESC? Best bet would be to open yours and measure it out, but odds are you’d have to modify the heatsink to make it fit

With heatsink modification, or outright heatsink replacement, absolutely doable.

I just received mine and I can say that the quality of the in and exterior is really nice and has a premium feel to it, but you should probably switch to different screws, because two out of the four screws on mine just snapped of when I applied the tiniest bit of force to them.

Is that red threadlocker on them? You’d have to heat up the bolt before undoing it if that’s the case. But on an ESC red threadlocker shouldn’t be used to begin with, because you don’t want to damage it from applying heat. Blue would be more appropriate…

Huh?

How? Why?

mine had tiny bit of blue on each screw, that’s it

I literally just applied the tiniest amount on them and they just kinda disintegrated. I took out the remaining two screws and tried my hardest to recreate them breaking, but they held up perfectly, so I guess it was just these two screws that were affected.:thinking:

I tried to take a close up picture of the point where it broke, but this is the best I could manage to take with my phones Camara:


That is weird for sure but why were you taking it apart?

I am using it to replace my unity, but the power cable is on the other side, so I plan to replace the original 10 cm 12 awg with a 25cm 10 awg cable, so I can loop it to the other side, where my battery connector is located.
And I wanted to see if there is also a second hidden uart port inside the enclosure, just like on the Go-FOC HI100.

Ah gotcha. Yeah those are some weak bolts, that or they were overtorqued

Doesn’t fit quite as well as I would have hoped, have to put it in sideways…I should’ve gotten a regular DV4 :sweat_smile:

Also I just realized there’s a PWM pin on one UART port and a momentary switch pin on the second UART…why not leave the PWM port as it is and have a 3 pin switch port?

I gotta say the packaging job was absolutely minty :ok_hand:t3:

Mine arrived today and was also packaged nicely.

Still can’t get over how tiny this thing is.

Classic wrapping up the small Xmas pressie in a massive box syndrome.
Packed to withstand an airstrike. :ok_hand:

Maybe this batch of screws is of poor quality.

That’s an M3x8 socket head cup head screw.

Note:

Be careful not to break the USB socket when removing the case.

When replacing the motor wire, you need to pay attention not to use too high a temperature for too long, because the bottom of the motor wire is MOS, which may cause the MOS to fall off

Private disassembly may lose the right to free warranty😳

Observations so far.

So it’s small. But the switch is large. Impossible to fit in our enclosure.
The switch takes up a uart socket. So no logger and uart controller.
Motor detection went well.
Can’t seem to get the Ppm socket to work but will connect to the computer and do some fiddling when I get time.

It has a harness that splits the UART and switch

So it has! :face_with_peeking_eye:

Although the button lights up and turns on.
It won’t switch the esc off. :face_with_diagonal_mouth:

Hold it down for longer?

What’s making those tunes?

Robogotchi.
Tried holding for 5,10,15 seconds.
Still stays on. :thinking:
