PROJECT: ENDGAME a karting inspired raceboard's development

So cool dude.how far did you have to drive for this one?

This one was only 700km/ 430mi each way. That’s the closest one we have :rofl:

Most often its in the 900-1100km range. Furthest is usually around 1400-1500km each way. I have a friend who also comes to most and then we share the driving. I’ve done 1500km alone before in one day and it’s rough.

Yeah

To me that is really really far …

Hey I know that track :heart_eyes: been there last year for gokart. Nice to see they have esk8s. What event was that?

Edit: now I saw you already answered a bit to that. You know how much the evening was there?

We paid 25eur per person so relatively cheap, unfortunately they are demolishing the industrial estate it’s on at the end of the year.

Was chatting to the local riders and they hope on getting one more event in for PEVs

Otherwise we have xErace in Wuppertal coming up in April if you’re local to the area.

Located in Hamburg. But willing to travel :wink:
Some thread you can recommend to keep informed about upcoming events?

You should follow this thread

Most of the track riding in Europe is organized by xerace, here you can find all xerace dates and locations, including the wuppertal race on april 25

Alright sir Bence. Starting my own 10” build soon. What tire have you had the most luck with? I hear wet/rain compound is the best for us but what has been your experience on asphalt and indoors?

I did most of the riding in decent weather on slicks and I’ve been very happy with them, especially on abrasive surfaces. Generally speaking the more abrasive the surface is, the better they perform. On very smooth fine grain asphalt they didn’t have perfect traction.

No outdoor ride on wets yet, only indoor rides. I’ll do an outdoor session on the new wets I have within the next few days. From my indoor testing of wets, they have almost all of their grip available by the end of the outlap, and I could get to the point where grip just about started fading in November in around 5-6 laps at Pitland. Worth noting that I was on unknown / bad condition wets (that I took for free from the karting place).

Indoor I did some comparisons in November (Pitland) of wets vs slicks, and the slicks had the same or maybe even slightly better grip after a few laps - but the grip just wasn’t there for the first few laps. Until temperatures are low I would stick with wets, but as soon as the ambient temps get high, slicks will offer more performance in my limited testing.

I think the reason why wets are the standard on stooge chassis’ is that they have more slip angle and higher slip angle tires seem to synergize with stooge chassis. I designed my own chassis around low slip angle tires, slicks feel even more direct and they have basically zero slip angle and perfect predictability [in good weather]. But to get the most control out of the chassis, low slip angle tires really benefit from flexy decks or truck angle increasing geometry.

Are these the tires and wheels from AliExpress? Besides those, do I need a bracket to attach the pulley?

You should look for name brand kart tires. Lecont, Vega, MG, Hoosier. You won’t find either on aliexpress. Look for karting focused webshops. All tires should be 10x4.5-5, if you buy full kits you receive 2x that and 2x even bigger tires which aren’t good for esk8 use.

Before you buy any rims, find some wheelhubs first that support esk8 pulley mounting patterns - there aren’t many options at the moment (I’ll be making some in a month or two). I don’t think traditional belt setups will work with these, open gear is your only safe bet right now, until I get to making some enclosed gear drives for them (few months). After you got hubs look for rims that fit those hubs and have a 5" diameter, and somewhere around 5" width.

Also anything less than 12mm axle on your trucks and I can almost guarantee you’ll bend them. You need strong trucks. And then you’ll also need to extend the wheelbase of your board otherwise you’ll have wheelbite.

Great explanation, thank you! I feel like I need to study this!

Some general updates regarding the production of this board - my CNC motion control system is finally figured out. The 40 year old steppers/ stepper drive definitely caused some headaches but they are working well enough for now, I needed to create a custom intermediary PCB to get it working. More on that in my CNC build thread when I have a bit more time to document stuff in a few days.

The rest of the electronics should just be plug and play and very simple to wire up. I’ll finish wiring tomorrow, then make the enclosure Monday. I’ll start cutting out the first chassis from wood on Wednesday - this will be just a mockup and not actually something rideable. I just want to verify my gcode before doing the real aluminium parts - messing up in the alu would suck a lot. I’m hoping to do the first test ride in about 2 weeks.

After countless hours of hard work… It’s finally working

Doing some test cuts in a bit.

It’s a testament to how much of a maker this guy is, that building a CNC mill is the side project.
