Here's a quick idea I had in regards to compact portal hub upgrade: -
Axle Collection Thread
Zerobricks replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Inspired by the 42177 topic - specifically a 4x4 squared mod, I designed a very compact independent suspension with brick-built portal axles which also feature a proper hub bearing. They are actually same width as the 42110's saxles and only 2 studs wider than the 42177's axles: By using 5L links and double headed CV joints, I was able to make the suspension arms narrower: Additionaly, hubs are also very compact by meshing a 20 tooth spur gear to a 12 tooth bevel gear: While this setup is very compact, it is not suitable for high loads, so I recommend it for manual models only. Also please note, this is just a quick sketch up, I only built one hub IRL. LDD file is available here: https://bricksafe.com/files/Zblj/Misc/Compact independent portal axle.lxf -

True. You can make an even more compact brick-built hub using the 99773 pieces and by skipping the hub bearings, but then it will not be as stiff... But I think we may be getting off-topic. -

From my experiences building fast motorized cars... usually not, as long as the suspension angles are low. In this specific case it would actually cause toe-in which is much better than toe-out. -

You can always build a portal hub that fits the Defender rim like I did with my Tiger 6x6: -

Looking at the video of the build, the front shocks are fixed to the frame, so I'd say no. -

I'm really happy I managed to catch not one, but two new lurkers , thanks for the praise! I just received the missing parts, so I will record a video in the upcoming days. Yes, the windscreen color is tricky, but I decided to go black, since the 45° brick holding it is also black.- 20 replies

Also, both sides are 45 degrees offset, the one on the left uses a grey version of the knob gear. -

Thanks for the praise. Indeed, you can see body bend and flex a bit in the slow motion video, the lack of a tructural support roof is quite visible. But I actually like it that way, it's more realistic and dramatic!- 20 replies

I take my previous comment back then. But it would make sense for new conenctors to be in 11,25° interval, so you can have even angular spacings. -

Another mod idea is making the Squared MOD with portal hubs and larger tyres, mudguards and other details. -

Thank your for the praise. It readjusts thanks to the shock absorber which is supporting most of the weight, so a purely mechanical solution.- 20 replies

[TC27] Lowrider
Zerobricks replied to Zerobricks's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I replaced the front PF L motors with the PU L ones and the whole model is now using a single BuWizz 3.0 in place of 2x 2.0 units. Even though PU L motors overheat faster than PF ones, I was able to record this quick and dirty teaser:- 20 replies

That happens many time during photo sessions, bricks simply slide apart, there's no correlation between suspension and grille IMO. -

I doubt, as causal builders are already mixing up #3, #4 and #5 ones. Having even more ones and and in the same color would be too confusing. -

[TC27] Lowrider
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here's my entry for the TC27 - the physical model is also completed and tested, but I'm stil waiting for the 2x C frames (3167) to arrive (for testing purpose I just 3D printed my own pieces ). Anyway, I wanted to build something unique and different this time around. I've been thinking of building a motorized lowrider for a while now and this challenge was the perfect excuse to realize it. With this model I wanted to realize the following functions: Motorized suspension Steering mechanism connected to the steering wheel Working fake engine driven by rear wheels Openable (suicide) doors, hood and boot Proper, clean and spacious interior Along with those functions I also managed to squeeze one more additional function, which makes the car a convertable. Here's the end (digital) result: So as you can see, it actually uses the correct tires and rims which I think is a good start! Here's how it looks like all opened up - notice the inline 4 fake engine: Here's a look from the rear, showcasing the large rear typical of lowriders, which is also used to house the two BuWizz 2.0 bricks. I took great care to give the model some fins, proper brick-built lights, bumper, exhausts, etc... Looking at the underside you can see that the L motors are also structural, both axles are designed around them: And here's how the Driveline, Steering and Suspension system are integrated into the model: As mentioned before this is also a convertible which means that the roof can be unfolded and raised: Now for a little of backstory. Originally I tried using PU L motors to make this model a bit more intelligent and capable of holding the wheel suspension positions automacally. Unfortunately PU motors have a very sensitive current protection and were simply not capable of holding the weight of the car even though I'm using shock absorbers to help carry weight. Worth mentioning is also that suspension arms are shorter in the rear to compensate for extra weight. I could have added extra gearing, but that would make the model even bigger and suspension slower. So I took some L motors I had laying around from the Go-Kart project and used them in place of PU ones. Thanks to their shorter size I even gained some additional space and reduced complexity. During testing I decided to double up the BuWizz bricks. I did that for two reasons, first to increase the weight in the back for higher front bounces and secondly to supply the needed power to actuate 4L motor at maximum speed at the same time (each motor draws some 2 Amps when stalled in Ludicrous mode). I hope that's enough details and media for now, I will post photos of the real deal once I get the missing parts and I will of course record a proper video.- 20 replies

A normal Inline 6 would be too big to scale properly. Besides, they designed a whole new piston and cam system to make the small piston engines as smooth possible. The fenders from the 42110 would not fit the style and the new tyres are bigger, so they may simply be too small. I also like how it does not rely on specialized panels (fenders) for the bodywork which means it should be easy to recolor in black, red, yellow, dark bluish grey, white and probably even more colors. Can't wait to get my paws on one and motorize it! I for one think it's a good set given the limitations designers face with a commercial product vs a MOC. The new tyres are really a welcomed addition to line up, they seem to have a smillar pattern as the Audi's ones. Regarding functions, there's at least rear locking diff, though I have a feeling one of the 2 - 3 levers hides even more functionality. Can't wait how to see how the rear suspension was designed, since there are no visible shock absorbers.
