Working on it, long path to go, so far just the concept.

Is that a differential gear set? Potential for a limited slip type clutch to drive both wheels in low traction situations?

Prototypes should never go to waste. I scored a pair of the 2023 3-link from Andrew Liang a few months ago, finally built into something interesting.
Shortcut to that super-low deck height + extended wheelbase = tips sawed off of a Beercan Boards Kegger deck I used as a standing platform for another build (LDP style w/ drop brackets.) Wheelbase with channel trucks was 38.5in, and I got wheel bite even with 150mm in front. Wheelbase here is 42in, no bite with any tires, room for more steering angle.
Note that the rod ends are mounted to the top of the hanger/axle instead of the bottom. Functions the same, but with reduced steering angle vs top attachment. I had no idea how they belonged, just found this thread.
FWIW, the board seemed to vibrate, make noise… I think it was the just the straps singing in the breeze on my brief test run. I think the all-rigid connection between motors and my feet are to blame, amplify any noise. The Aluminum deck tips are stiff, and have mostly full face contact with the deck tip. I’ve never felt the road to this degree, and this on relatively fat 175mm tires. I’m insanely excited to lap this thing tonight on smooth concrete. (Lexus Velodrome FTW)
P-clips for the harness, proper tightening of preload nuts on the list. (I realize this is an un-finished death trap.)

I’m sorry, just had to post #666 here for good luck. I love how low this thing turned out. Canned Flux lives!

This is a project I’ve been thinking about recently. I want to develop an open-source race board frame, combining carbon fiber tubes and 3D printing. Once the project is complete, I will share all the frame files. Users will be free to adjust the length, modify the concave, or add new ideas to the design.
I will keep updates more infors in this thread.

Was inspired by dani, this time i was considering combine the tube to the truck baseplate

Can’t wait for the day we can have LSDs on esk8s

I think having a pair of carbon fiber tubes down the center connected to brackets holding the trucks would work well. Combines with a deck, you could create racing chassis with almost no torsional flex.
I made these “LSD’s”

You can, just watch out for the moving potholes.
Oh you mean like a differential, that too I guess.

Yep, with a deck it works,
But I’m into a fully custom frame building, in the middle it going to use 30*30 square cf tube to solve that that, with a deck it work easier idk.

Re wanting a real LSD… Does Stooge bother with any sort of mechanical diff for their single motor boards, or do they run with a solid axle, live with the tire scrub? I didn’t notice any single-motor boards this year, but heard them mentioned.
Canned Flux was short-lived… Board was a dream on smooth concrete with no grip, but in a 5-min session on actual pavement (the practice track at esk8con) the front truck fell apart.
The nose piece had so much force on it, it rotated and bent the saddle in which it sits, bent the screw, ripped the threads out. The last spoke was machined so thin that there was only about 1mm of material around some of the saddle where the “nose” sits.
I intend to repair the threads, (drill over-size, tap for helicoil insert w/ 1/4-28 thread to match drilled-out nose) bolt in place, then have it welded permanently in place.
FWIW, the board was a DREAM on Nova 175s on Phatlads w/ 5.41:1 reduction (14/76) and 138kv Reachers at 18s. I intend to revive and race this with somebody’s 3-links.
Building and racing this thing even for only a couple weeks was a HUGE learning experience.

No diff on the stooge SSS boards. Not sure how many of those are still out there running around

I gather that everyone involved in developing and testing these has moved-on. I thank you for trying to perfect these, but now agree that they are fatally flawed. My front truck fell apart from stress on the “nose” piece bending both the Aluminum saddle it sits in, and the hardened screw securing it. Even with a tight screw, the metal deformed* I note that the last spoke, right behind this saddle, is only 1-2mm thick! I won’t bother re-designing this part, but will instead have somebody (a competent welder = not me) weld the nose to the saddle after I’ve repaired the threads. Gory photos as soon as it rains. (Skating trumps broken part photo session atm)

If Ean can create a good quality differential, it could be really help push the limits of racing.

Is there anyone to receive those trucks or esk8? I’m really curious about how well this product performs.
