Hey Everyone!

Here is the successor to my Lego Technic Chili Crawler.
It took about half of a year of design and revision to reach its current state, of which I am proud of.
Features:
- 3 L-Motors for drive (two in the rear axle, one in the front)
- M-Motor and a small linear actuator for front steering
- Rigid, triangulated 4-link suspension for the front axle, with large, soft, black shock absorbers
- Extremely rigid 2-link rear suspension with ball-joint pivot point on top of the axle, similar to that found in the RC "Mantis" crawler
- 100% Lego-legal custom curved rear links that, with how the main cab is shaped, provide exceptional ground clearance towards the rear of the crawler, allowing it to climb up relatively large vertical structures such as street curbs
- Very minimal, light bodywork
- BuWizz for extra power and SBrick for a great, custom control scheme
Note: By the time I finished designing the cab and it's battery enclosure, BuWuzz had not yet come out with the update for their iOS app that allows a single joystick/slider to control multiple outputs, so I was forced to use an SBrick with the BuWizz, providing the extra power from the BuWizz, but with the ease-of-use and great custom control profiles of the SBrick. When used with the SBrick, the BuWizz does in fact still provide more power than the standard Lego 8878 LiPo battery box.
- RC4WD 1.9" Krypton scale tires
- Two green pieces so that I can call it the Cactus Crawler ;)
If you like my crawler, please like my video.
Enjoy!
thats such a ridiculously minimalistic design. love it.
Just as a reminder to everyone, I build performance-focused crawlers, which often means that there will be no body and/or the cab will look quite bare. In this case, I built the cab to be as small, light, and rigid as possible; it may just look a bit weird. Feel free, however, to comment about its weirdness all you'd like :)
Please answer my question ;)
I wish i had this weirdness with me, you owesome creator man, i like your style 🥰, i wont comment on each one that i like becuase it will take too much time😉.
You get sub regardless your builds are what I’ve been trying to do my entire life with technic
I love your moc, because everyone uses xl motors and you show that it also works extremely good only with motors!
I like this type of vehicles (built some myself). You've done a very good job!
Many people say that you cannot achieve real RC car performance with Legos but I believe you have. Good job!
NICE, waiting for your LDD file, can not wait any more to rebuild it
Cactus Crawler instructions now available! Check the description.
Finally instructions, Downloading now!!!
Wdym it’s just an Lxf that isn’t intructions🤔
Been watching alot of lego crawler builds on youtube and i have to say this is by far the best performing one ive seen. Im also quite the minimalist myself so i love the simple and efficient design. Awesome.
Perfect crawler, except for bodywork, please put more than just 2 pieces into that amazing crawler! ;)
Haha, I agree that it does look a bit skeletal. Thanks for being so punctual on watching my new video, despite me not giving a specific upload time!
That's really cool too bad Lego does not make tires like that
Hello, I really like your solution, is it possible to get instructions from you to build your RC?
Great crawler and really nice views!
When looking at the rim, it seems to be a 56mm (OD, 7stud) rim / 34mm (width). That conveys to 2,2 inches. How do you fit a 1,9 inch tyre on that. What am I not seeing / understanding.
Crazy.. I downloaded the lxt file for your chili crawler only last week. And ordered some parts to build it this weekend. Guess my plans have changed.
Good work
Thank you! However, I encourage you to build the Chili Crawler as well as, not only is it a good, reliable crawler, but I cannot guaruntee a timely completion and uploading of the LXF. :/ ;)
I love this crawler!!!Where i can find instruction for it?
Very cool video and so funny edit !
I like it ! That's really great !
Cool! When will you upload the instruction?
Cactus Crawler instructions now available! Check the description.
Perfect model. I will try to do the same. Why did you used sbrick also since buwizz has the control ability via Bluetooth
38 pieces in middle got removed
Its cool to see someone building competition style MOA crawlers from lego. Is the rear axle torsion style? If yes how did you manage it with stiff lego pieces?
Thank you and that is what I am aiming for in my crawlers: performance. I suppose you could call the rear axle torsion. It is 3 link, so one static ball-join at the top of the axle and two freely moving links on either side. The flexible grey ribbed hoses on either side to help the axle return to center. The ball joins have quite a bit of grip which means that without the hoses the rear axle may be too stiff to return to the center.
Is there a way to use the old double a battery pack and still maintain the low cg? I have fully built it but dont have a buzwiz and am not sure of a good mounting position to keep it similar.
Nice one, i realy like you Design.👍
Nice Crawler i like your concept but the drivers cap does not look like a Rock Crawler .Mantis idea is great keep it up.(Mark 4 is finished)
Mark 4!? I'll go check that out!
Great crawler!
I think it can compete with real RC-crawlers.
When will your new crawler with the bully-tires come out?
Really looking forward to it!
PS: Can you do a 3rd party tire comparison?
Thanks ;)

Hiya, I have a question I've not seen answered below: how can you link the Buwizz and SBrick together so that the SBrick controls the output from the Buwizz?
The SBrick does not control the outputs of the BuWizz. Instead, I use the BuWizz as a power supply as you would a Lego 8878 rechargable battery box, as the BuWizz is smaller, lighter, easier to mount, and more powerful. I turn on the BuWizz, connect to it on the app on my iPhone, then switch to the SBrick app to control the crawler. The power levels (slow, normal, fast) on the BuWizz app still work; this doesn't matter, though, as I always have it on the fast setting.😬
PunkTacoNYC thanks for the information.
So you're effectively jamming the throttle open and letting the sbrick control what it does; nice!
How do you connect the s brick to buwizz
The SBrick used the BuWizz as a battery just like the Lego 8878 LiPo battery.
PunkTacoNYC i figures it out because the ludicrous enabled one only works with two devices
#1
i cant access it can you make another link
Just did, check description.
I’ll try stud.io 2.0
