Evan's 1st Mountainboard | The Apex Croix - 4wd atrocity

Motor name obscured by paint, (wasn’t me)

It’s 63xx, directly measure ur the length of ur laminated core (25mm), both are 16t (turns of wire around the core arm)

Feels like 150, could be 170kv

The YouTube RC car guys will give you brain worms with different ways to characterize a motor.

Bet they are the same motor. Inside of can looks better than yours. What did those poor hall sensors do you to be sheared off?

How did you get so much dirt in there?

Awesome - thanks Mike. I’ll take these off your hands. No sensors is all good with me. silent HFI works great on these little motors. High ld-lq to overall inductance makes HFI happy.

One of them had scuffs on it, and I thought it might be hitting the magnets and causing bad freeroll, so I ripped them all off. They were dead anyway.

I just did a lot of offroading on dusty dirt roads and ATV trails. I guess the dust gets in and doesn’t have a way to get out.

I know exactly what you’re talking about. There’s a method that involves a drill and a volt meter.

Dude, you are a monster.

Prompt and execution

A dramatic and dark fantasy scene featuring an anthropomorphic Hall sensor IC, standing defeated in the center of a bright white spotlight.

The silver pins forming its arms and legs are bent, while its matte black rectangular body is bowed forward, head hanging low. The distinct arrangement of letters and numbers on its body forms a sad grimace, and a chipped corner on its head signifies poor health and injury. The name “Hall” is written on its forehead, and its sadness is palpable. Beyond the spotlight, the words “YOU ARE DEAD TO ME!” stand out in bold, striking font, casting a shadow on the scene. The powerful visual metaphor of failure and disappointment is both captivating and thought-provoking., dark fantasy, typography, cinematic

Can mail them, but If you are in the neighborhood, bring the other two. We can battle harden them with a handful I’ve been needing to do. Still have the materials from the last run.

APEX CROIX REBUILD: I decided to refresh the board and turn the Apex Croix into the Rally Croix

I worked with @Skyart and @MoeStooge to make HD 3-links with a 22mm profile adapter to fit my Apex jump drives. They fit great - thanks Moe.

Goals for the refresh include more turning and lower ride height.

Plan is to use a short link in front and a long link flipped reverse in rear. In my mind this was a symmetrical setup, which turned out to not be true. Unfortunately, I made some bad assumptions with this build, but that’s DIY for ya. It will be fine in the end. Just needs a bit more power tooling than I expected.

Parts arrived:

Stripping down the build

I took the motors apart to clean them - can you tell which one was one the rear? lol.


Swapping Apex parts for 12mm to use 10mm bearings and spacers.

Parts on and feeling good at this point.


Where I start to realize that I have screwed something up. The front of the board is facing way down. This does not feel good.

Reason #1 - I overlooked that the short links have a shorter master heim than the long links do.


No problem, we can fix that.




uhhh, shit… still not level. still facing down. what the %^&*

Realization #2: short links have longer wheelbase than the flipped long links (axle is further away from the deck).


Solution = drop it lower in rear


STILL UNEVEN… Realize that the split angles on the lacroix deck are affecting the level. So I put a total of 10 degrees of angled risers on the front truck. (yes, I hate this too, but I’m desperate at this point to just get this damn thing level)

The deck is finally level and rideable. No wheel bite on 8" wheels.



Turn test - the front short links turn a LOT

Flex test. The flex is ridiculous with all the leverage from the extension brackets.

All in all I’m stoked on how this thing is turning out. I haven’t taken it for a ride yet, but first impressions are that this thing is going to be ridiculously fun.

I’m not satisfied with the front truck wheelbase and janky angled risers, and I’m debating whether I should drill new holes in the extension bracket so that I can bring the front axle ~2cm closer to the deck. Right now, I have 8" wheels on the board that @Skyart is letting me test out, but I could fit 9" tires on the board without wheelbite. If I shorten the extender bracket, I don’t think I can run 9" tires anymore… decisions :slight_smile:

@rafaelinmissouri I know you were interested in this, so here are a couple thoughts on the 3 link mountain board approach.

  1. The short link in front causes challenges, but it’s basically required to use the short link instead of the long link to avoid wheelbite. If you were using wheels smaller than 8" or are ok with chopping the deck a little like @Yeahthatperson did, you could use a regular long link in front too.
  2. Having 4wd adds additional restraints here. I do not think the front motors would clear long links facing forward in front.
  3. If I was starting from the bottom and doing this again, I would probably do just a 2wd board with regular (long) HD 3-links. I would still use the extension brackets. Run the rear flipped, and the front links facing forward. Cut the front of the deck as needed to avoid wheelbite. If anything, I’m finding that the short link in front turns borderline too much. So I think a long link up front would do well on this setup. Again, the front motors prevent me from doing much different from my current setup, but for 2wd, I think long links all around is probably the move.

Dude.

I’m looking forward to you riding this thing with these trucks.

I’m currently mad at them because they ruined the Flux for me…

On the Esk8 Nomad interview I think Moe mentioned they are going to work on an angle board version of the Mad Links.

I am looking forward to seeing them come to life.

So low.

I don’t think I could run the Flux with the bottom enclosure that low.

I just took it out for a ride and it’s like a magic carpet. It’s a ridiculous board.

I do think I went a little too extreme on it though. The front axle is a little too far ahead of the board.

I think maybe I should have done a normal long link in the front. Looking at Chris’s rally bro, 4wd would be no problem. That leaves wheelbite as an issue though.


Pic from @Yeahthatperson thread here: Rally Bro - A Yeahthatperson Build

Current state is close to an inch of wheel clearance at full lean.

Moving to long link truck would lose a ~1.5” in wheelbase. I think this is too much wheelbase to lose. I definitely want to be able to run 8” tires on this deck. I’m ok with sanding down the lacroix deck if needed, but I don’t want to start hacking off chunks of it.

I think the best option I have is to DIY the front extension bracket a bit. Plan is to drill new truck holes in the @Skyart bracket to bring the truck in only 1”. This should make the front shortlink match the wheelbase of the reversed rear long link.

Wish me luck. I’ll be using a hand drill and antisink plates as a drill jig. :joy:

Those tires look cool.

Were you running 8 or 9 right before the change?

They have very good balance. I was on 9” mudpluggers before. The mudlpggers are 10/10 for off-road but probably not the best if you’re doing a lot of road riding. I started with 8” here because I expected wheelbite to be an issue.

Possible to go wider? I have Tito duality with a 45deg angle up front on a old haero (no wheel cutouts like the new ones) and no wheel bite with 9in wheels

Unfortunately no, this is as wide as I can go on these axles.

I have thought that risers might be better than the extension brackets for the front truck, so I’m going to mock that up today and see how it looks.

Not with your scrawny ass on there maybe. My ass was a different story :joy:
