Carbon GTO | 10S4P | TB110 78A | dual FOCBOX 1.6 | dual enertion 6355 | Boardnamics 220 | Carbon GT deck [serious]

So once upon a time there was an Evolve board —

Ok so, I was going to change ONLY THE CELLS in the Carbon GT since

All it really needed to not suck complete ass – was new cells. Same BMS, same ESC, same motors, same drivetrain, same deck, because … welp, the board worked. Performance was terrible, but it did work. It functioned properly and didn’t suffer from the notorious “Evolve drop-out” problems. Aside from the cells being absolutely worthless, it was a perfectly functional board.

Fast-forward and one thing led to another, and when I was actually done, the only original Evolve pieces left are

  • deck & lid (but not the bolts)
  • 4 heatsink bolts (but not the heatsink)
  • 2 plastic cable clamps

That’s it. Nearly a Ship of Theseus. New cells, BMS, antispark, charge jack, motors, trucks, motor mounts, wheels, pulleys, new ESCs, new heatsink, new lid bolts, new risers, new lights, new remote, phase wires, bluetooth, everything is new except the 3 parts listed above. And now it’s RKP instead of DKP. I personally prefer DKP on the front and RKP on the rear, but I didn’t want to deal with matching deck heights so I just put RKP on the front also.

So, what’s inside?

This skate consists of

I love the sound of those motors, they scream even in FOC mode. If you’re rolling at a nice clip and you mash the throttle, it sounds like a jet turbine.

I wish these lights ran from the main battery and didn’t need to be charged on their own, but they are better than the generation 1 Shredlights that were on this board before.

One thing that I’ve really, really noticed, is that this Carbon GTO board feels like twice as heavy as the Carbon GT did. It’s probably not actually twice as heavy, but it’s definitely a lot heavier.

The Gamer43/Haggy antispark is nice as it’s roll-to-start and there is no loopkey or power button at all. Just turn the wheels and it powers up, and after 10 minutes of inactivity, it powers down.

Shout-outs

Massive shout-out to @Sn4Pz for the metr Pro

@DerelictRobot your peer pressure worked

Thank you @Arzamenable for selling me this heatsink, this made everything a thousand times better

@KaramQ thank you for selling me these OG enertion 6355 motors. Reminds me of the Tacon motors that pixelsilva has, they look just like that except 190Kv. I love the sound those enertion 6355 motors make.

Thanks to @Kellag for selling me the frames and the lights

Shout out to @Scepterr to whom I farmed out the welding

Thanks to @Lennylogs for the cells

Thanks to Dexter at Torqueboards for continuing to push boundaries when it comes to polyurethane electric longboard wheels; best in the world

and I have no idea which two FOCBOXes these are, I took them from my stock, not sure from whom they came but they were bought used here on esk8.news, shout out to @longhairedboy and his dedicated mod team for that.

thanks to @PixelatedPolyeurthan for being helpful on the forum

Obligatory, “CF is conductive”.

RKP, on that deck is dance with wheel bite.

Also, nice :ok_hand:

The heatsinks to fit two FOCBOXes in here are not cheap and plentiful :sob:

You hoping never to get a corrupt bootloader? Nothing will ever come loose.

Haha it is fun to be going hard and looking behind you to see that car you heard coming only to realize your board is making that noise.

hehe guess you didn’t spot the USB port extensions :stuck_out_tongue_winking_eye:

@b264 I’m sure you thought of it, but cover up the exposed USB plugs

You use swd port to fix bootloader :stuck_out_tongue_closed_eyes:

it’s not a flipshit, can typically reload bootloader with vesctool

If that happens, I will deal with it at that time :rofl:

Has to be sealed to be waterproof.

Theoretically you could pour water inside the enclosure and start riding around… theoretically

Every PCB is sealed, the battery is sealed, everything is sealed, then the silicone on top of that…

Update bootloader yes, without working BL you can’t chicken and egg.

The external USB-A plugs were put in a little plastic bag with silicone at the open end and cable-tied closed on top of the wet silicone. Easy access, and easy waterproof. Looks, not as nice. Who cares.
