About the Six-gauge wiring buss, I had to redo it.
For the first version, I had planned to put the QS8 connector between the lipos and the tube. My Lipos being quite wide, I could not close the belly pan anymore.
I had underestimated the space that these connectors took. So I made something much compact.
I covered the welds with Sugru, the texture of which I modified with a metal cutter.
The spinal cord :
Hella clean, nice work!
That looks great! Well done!
Covering solder joints with sugru is brilliant. Nice work
Additional Aerodynamics
Sexy claspers on that build!
First ride today!
I was surprised how powerful the board feels in 8S.
I was also very surprised to see how comfortable this SuperSpine is. However, the roads near me are broken. I found it to be as comfortable as a not too flexy mountainboard with not too inflated pneumatic wheels.
By comparison, my Hummie deck associated with Hummie hubs is horribly more uncomfortable.
I had several problems:
IMHO the motor mount really lacks a key system, to prevent it from rotating around the axle. Mine moved after 100 meters and rubbed on the asphalt.
I had wheelbite at the front, at low speed. It brakes abruptly. To solve this problem, I spaced the wheels more with the spacers.
I did not change the basic settings and the brakes are too soft. I can’t claim to stop at a stop sign, even if I’m not arriving too fast. The braking curve is strange too. It seems that the outcome of the braking is conditioned by the way you attack the brakes when you start braking.
The surface of the hobbywing motor housings is a real cheese grater. It eats the silicone of the cables, the heatshrinks of the motor connectors, and your fingers…
I bought the OTA Programmers, and so far it’s really not great. The only thing that works well is the firmware update, which has never failed me. In Bluetooth, accessing the ESC settings, or the telemetry, is a pain. It almost never works.
Overall, I’m super satisfied with the feeling of this board!
I’ve had to fix my motor mounts (on my v5) a couple times. The solution is looooots of red locktite on the hanger and bolt. The bolt needs to be as tight as possible (short of stripping the bolt)
A bunch of SS riders here in socal have cut into into their decks to avoid needing to increase hanger width
I run vesc on all my boards. However, the lack of braking does match my experience with all of the hobbywing boards that I’ve seen/ridden.
Even with brakes set to 100% I still find it weak in comparison to VESC.
To protect the wires from the cheese grater I add extra heat shrink to the areas that touch the motor housing.
Weird I personally haven’t had issues with OTA programmer.
Do you connect through Bluetooth or Wifi?
Good to know!
Oh yeah definitely plus one to the red loctite once you have the angle you want. I also did this.
I use Bluetooth to connect, on iPhone.
I love this thing!
56 km/h max for now, according to the GPS sensor of the Insta360 One X.
I was a little disappointed because I thought I was going much faster. However, it is a 30 km/h road and there are bumpers.
I have already reached 60 km/h on an electric mountainboard, but with the noise of the gears, the low position of the deck and the wheels that stick to the road, it is much more sensational on the SuperSpine.
I set the brakes to 100% and I really think that it should not be less, and the punch to 4 instead of 5, because it already pushes really hard.
Still incredible for 8S. And considering the feeling of power, I am surprised not to have drawn more than 50A per ESC. I could have used AWG16 for the cables. 
I have two small problems:
On my route, there are not so many sharp turns, but I have the connectors that come off on one side, in particular because of the heatshink wrap which is a bit long but it is absolutely necessary to prevent the cables from rubbing against the motors which remain authentic cheese graters.
I put a little epoxy glue on the connector which tends to run away, because a little cyanolacrylic glue was not enough.
Arrived at 56 km/h, there is ultimately very little travel left at the trigger of my GT2B, while my theoretical Vmax would be around 73 km/h.
I think that the relationship between the trigger travel and the speed is not linear. The curve would be steep at the start, with a consequently very sharp acceleration, but would then have a slight slope after 2/3 of the trigger travel.
I will make a specific wiring to switch the beast to 12S2P instead of 8S3P, with the same gear ratio, to see the difference.
I have many boards, but this one is very special! 
I would be concerned if your cans are cutting through your cables and pulling the plugs. Id clock the motors lower or possibly look at flipping the escs the other way around. I know the spine has less clearance but I had more on the v5 with the escs flipped the opposite to yours vs as you have them now… The phase leads rest on the cans but I’m yet to see any wear on their insulation
Looks great! Im going to copy your spinal cord shape. One thing tho, from the Tessa Sugru site:
“ Be careful with electricity. Stick to small consumer electronics repairs, low current and below 24 volts.”
Thanks I didn’t know!! 
Maybe it would be better to put electrical tape on joints before applying sugru…
That’s what I’m going to do with the 12S spinal cord I’m building now.
As shown in the table, Sugru’s conductivity falls within the low to medium range, while metals used for gluing have significantly higher levels. This is due to Sugru’s primary composition as an insulator, with carbon black providing some level of conductivity.
| Material | Conductivity | Common Uses in Electrical Applications |
|---|---|---|
| Sugru | Low to medium (<10^-3 S/m) | Wire insulation, creating barriers around electronic components |
| Metal Glue (e.g. Super Glue) | High (~10^5 – 10^8 S/m) | Bonding metal parts or wires in electrical circuits |
| Electrical Tape | Medium to high (~10^-2 – 10^-1 S/m) | Insulating wires and cables, sealing electrical connections |
| Soldering Flux | High (~10^-1 – 10^0 S/m) | Aiding in the soldering process for strong electrical connections |
Does this tab mean electric tape is more conductive than Sugru!?
New spinal cord!
8S3P versus 12S2P (with 6x Turnigy Graphene Panther 6000mAh 4S 75C)
I didn’t try 12S yet.
But I rode my 12S2P VESC mountainboard with 80100 motors and 8 inches wheels for the first time in 2 months, during which I only used the SuperSpine.
It has lost a lot of flavor!
On the road, the SuperSpine in 8S3P seems more powerful with less Volts and less Amps, with a better autonomy!
The SuperSpine is more comfortable, even if the mountainboard tires were only inflated to 1.5 Bars.
No need to compare 3-links to channel trucks. The control is much better with the first ones.
Nice power harness!!
As someone that used to race Kaly channel’s, I agree with you.
Have you ridden dualities? Curious how you feel about them
The flash point is higher also… maybe its a liability thing that they put that on the site…
