There’s one annoying thing about this truck. It’s swapping out the boardside bushing. You would normally need to take the truck off the deck to take out the kingpin to be able to swap it.

I drilled a kingpin access hole into the deck in order to avoid having to take the truck off for bushing changes, as I plan to experiment with bushings quite a bit. For now I made this hole for the stock angle, I can widen it with a dremel sanding bit if I end up changing the angles with angled risers.

Wow, I was just about to thank you for laying to rest the question of whether long phase wires play nice. I’d sure love to clean up the ass end of my top-mount boards, race board especially so I can experiment with putting my back foot up on the tip a bit, and relocating the ESC(s) to the battery box/bag would do the trick. Seeing how a no load rev-up got you here to BBQ city, I think I’ll leave well-enough alone. Most recently, I’ve eschewed a heatsink and enclosure altogether, mounting a Flipsky 75/100 dual upsidedown w/ the thick base exposed directly to air (or thinly “clothed” under a newborn baby sized onesie.) This cut a good 2lbs from my ABS box + heatsink setup, has been working out well. TLDR: Ya think the super-long phase wires are playing havoc with the VESC?

I am pretty sure that the long phase wires are not problematic. I think the consensus is that long battery leads are more problematic.

The no load rev up was an issue because of setting an erpm limit. With the very high power level (200A per motor at full throttle, although i haven’t full throttled when it blew up) I think the vesc code was too slow and lost track of the motor when it reached the limit. If I had slow abs overcurrent off, that might have helped. With the new ESC I am going to keep it off.

I had another board as well where the esc was in the middle, and that’s dead reliable.

I’ve flipped them around before on axles I was really tight on space. The nylock gets a better engagement in my opinion.

I’m running long phase wires and it’s fine. So are @poastoast @Evwan @jack.luis @ShutterShock

I had some oddities with the first time I ran long phase wires to the point that I had to ditch the setup

Could it have been at the wheels are round? Every board I’ve ever had a DRV fault on has had round wheels

Both the motors and esc are on separate boards and work great individually.

The board is finally assembled! I’ve just done a test ride too. The trucks feel incredibly smooth and very turny.

And it’s a super nice and low ride height.

This ride I had 92.5A APS tall barrels front, 92.5A APS tall chubbies rear. Both needed a decent amount of preload. Stock 30/15 angles. I had to remove the front lean stopper, it felt way too restrictive. The rear was also removed but i stacked washers under the screws there to mostly add that feature back - in the end it only allows a tiny bit more lean in the back compared to stock.

These feel like the best trucks that I’ve ridden by a long shot. I have ridden srb and newbee 3 links before but neither were setup for my weight, therefore they didn’t feel good for me in that config.

The first impression was that they have a lot of turn. I am 3 degrees less truck angle both front and rear compared to the bn channel setup, and these have much more turn. These also feel very linear compared to channels. This meant that the first half a mile carving was definitely an adjustment period, as they carve differently. But after that… They allow crazy smooth and deep carving. I really like the setup as is, it’s very manouverable and felt very smooth and stable although I wasn’t pushing speeds yet

I’ll take them for a T-race session tomorrow hopefully

That’s why they call me skid mark :poop:

First track session on the new trucks done. Feels good to be back on the board. I still love how the trucks feel, but I am quite slow and rusty at the moment after the 3 week downtime. Also the track was quite slippery today in one corner. It hasn’t rained this week. 15.11 is my best time today. My rear thigh was burning at the end of the session

They felt very stable at the 46km/h top speed that I reached on track, and they are setup very turny.

I am actually not sure if I want to stay on 30/15 angles. Considering 30/10 or maybe even 25/10. Not because I need extra stability, just because I like when the deck leans a lot and these somehow feel like they turn more for the same amount of lean compared to channels? I don’t see how that’s possible from my understanding of the geometry, but it kinda feels like that… I think it’s worth experimenting with lower angles a bit just to get a bit more deck lean during the average turn and carve

On my way home after the session I heard a really loud pop coming from one of my rear wheels. I thought it was a flat but the tire didn’t feel softer than it was supposed to be. Maybe it was one of my 3d printed wideners, but those also don’t show anymore damage than they did previously. Maaybe the 3d printed lip broke off on one of them. They still felt completely fine though even at around 40 km/h on the way home after the noise. But I’ll inspect what happened.

Had another ride today. Holy shit these trucks are awesome. I’ve been carving on these at 30mph and it felt very planted and effortless. I have a very loose setup on these. They go also go over road imperfections much better than channels. There’s a path where the asphalt is very wavy and I can go twice the speed compared to channel trucks on that path. I haven’t tried them for real offroading though

If you want to carve at 30-32mph, maybe even higher, these are the absolute best trucks. For this purpose, the 9x3.5 slick CSTs complement the trucks super well and it feels like it’s on rails. Disclaimer: maybe 3 links might be better, however I am yet to try someone elses 3 link setup that I liked more then these, and I don’t have my own 3 link setup.

If you go at high speeds in a straight line, it doesn’t get twitchy like channels, because you do have resistance around the center. Makes high speeds much more fun and comfortable. It just feels linear and predictable.

This was my first ride on them when I was pushing the speeds a bit. I am confident there’s much more speed in the trucks, but I am not really used to these speeds after spending the last 1.5 years on loosely setup channel trucks exclusively, so I rather build up confidence slowly

So true. I wasn’t a high-speed carver until a few days ago, cruising on Nothing Fancy.

I joked last night that the trucks are so stable it’s like they take some of the fun out of carving :joy:

There’s times on track with nothing fancy that I forget I’m not on three links. The feeling is very comparable, especially with how low we’ve got our ride heights set up.

Hahaha so true. They don’t have the progressiveness of channels, it’s definitely a new feeling. But they ruined channels for me :grin:

You need to at least overtake all the 3 links on the t-race leaderboard to claim they’re better :wink:

Hahaha well I don’t think that’ll happen for now. May also be a skill issue though :laughing:

Been way too busy with exams in the last two weeks, but today I finally had the time to go for some rides.

I did a T-race session and went for a ride afterwards.

I am quite slow at the moment I need to get back out there more frequently, which I will mostly have the time for from now on. I haven’t stood on the board in two weeks.

Interestingly I noticed a trend for todays laps: the shorter distance I complete the track in, the faster my time is. At least that was the trend today. However previously I benefited from taking the slow corners faster with slightly longer distance travelled. And I feel like there’s not much more in me if I only try minimising distance. On the channels turns this tight were impossible though.

I think I should I give up the line a bit in favor of speed, so I am hoping to try 25/10 angles next session to allow a bit more lean.

And here’s the ride log afterwards. Slowly starting to get used to the higher speeds. Notable that the board felt very planted and stable even with going over bumps at these speeds, channels would oscillate if I hit a bump this fast. I am very impressed with the stability considering how turny and reactive the trucks are setup. And every time I push myself to go faster I realise it’s still stable. There was zero sign of instability so far. But I am playing it safe and building up the speeds slowly

Same, at 30~35 mph. Curious where that point is on these trucks
