Thank you, I appreciate it! True, the electronics make up a large portion of the overall cost. Fortunately, some of those components can still be bought for a fair price second hand and additionally there are other brands offering structurally identical components. This is a great alternative for any MOC, especially considering the servo motors, which are still quite expensive even on the used market.

42213 Ford Bronco SUV
burak replied to Ngoc Nguyen's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Sadly it looks like this is just part 2477 in red If you are referring to the parts near the door hinge, looking at the high-res images on the Finnish lego page I'm pretty sure this is also part 2477. The front independent suspension is made up of 4x 5977, which appeared first in the F1 sets, so I still consider them pretty rare. All in all a pretty nice parts pack, especially for the already discounted price some dealers offer. -
42177 Mercedes G500 4X4

While filming for a MOC project I realized, that so far I haven't seen the G with the LBG rims from the AT-AT. I think black is the better fit, especially with the hub caps on. But the LBG ones give some nice contrast to the model -

Incredibly well thought out model. Iconic looks, lots of functions but also nice details in the engine bay and interior. The best part is the portal axles -
Cool model, a pretty minimalistic build with the main focus on its capability. That onboard shot was very cool Would love to see more use of onboard cams in truck trials, but I believe the added weight would be too big of a disadvantage

Phenomenal model, it looks very recognizable from most angles. I especially like how you mimicked the flow of lines on the bodywork in the rear and on the roof. The only part that could be improved in my opinion is the hood. The fenders of the original are a bit taller than the middle section of the hood, the vents are missing in your model and it would be nice if the hood was hinged in the front, as in the original. But of course this is a b-model, and there is always a little bit of compromise to be made. Overall great job!

So I got the G500 and before building it I had to try the new tires on the Defender (as requested by @nerdsforprez ). They fit without problems, there is no rubbing when steering or raising and lowering the air suspension and wheel articulation is still as great as it was with the stock tires. Here's a few quick pictures I took, what do you think?

Most likely. Perhaps TLG is still checking whether paper bags in this form are generally accepted before all factories finally switch over -
Then I would suggest to get rid of those 8-tooth gears near the differentials. They are going to break sooner rather than later if you plan to do some serious driving. What you could do is to use the new-type differential but with the red 28-tooth gear instead and mesh it with a regular 28-tooth gear. That way you'll have one gear transition less and a more robust drivetrain.

I've heard or read somewhere that apparently the same goes for sets sold in Australia. No idea why though -
Hi everyone, I would like to share with you my extensive mods of the set, which resulted in the slightly longer Defender 110 version with many RC and manual functions. I’ve worked a few years on it and during that time I checked this forum regularly for some inspiration. It was interesting to see what others have come up with. The RC functions are: All-wheel drive through 3 differentials Steering with Ackermann geometry and working steering wheel Signature front and rear LED lights Center, front and rear differential lockers with 4 individual locking modes Adjustable air suspension providing variable adjustment of ground clearance from 22mm / 2,75 studs up to 32mm / 4 studs Auto-compressor powering the differential lockers and air suspension, which automatically shuts on and off at fixed system pressures There’s also a detailed and spacious interior, which mostly keeps the RC functions hidden while providing additional manual functions: Working door locks on all 5 doors Adjustable and foldable front seats and completely foldable 2nd row Spacious loadspace Small details such as air vents, climate controls, storage compartments in all 4 passenger doors and between the front seats I am currently developing additional interior mods such as a 3rd row of seats, an optional 3rd seat or cabin walkthrough in the front and a panoramic roof. If you’re interested in seeing a more detailed presentation, additional pictures and a video you can check out my whole post here:

"Big Grey" 8x8 Trial Truck
burak replied to 2GodBDGlory's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
You're right, the part variety has indeed gotten better in recent years. But I'm missing a few more types of mudguard panels in DBG, there's only the ones from the Peugeot. Granted mudguards are very specialized parts, but they make color swapping a certain set or MOC very difficult without compromising on the looks. -
"Big Grey" 8x8 Trial Truck
burak replied to 2GodBDGlory's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The body looks a bit generic but the internals are pretty clever. It would be interesting to see or hear how it performs in the upcoming competition. And I like the color very much, I wish there was more pieces available in DBG -
Thank you very much for your feedback! I thought of ways to show off the different diff locking modes and their effects and this seemed like the best option. To make the effects visible the dyno had to provide different rolling resistances on each wheel, so there is a few different gear ratios going on. I'm actually pretty excited about the G500, it would make an interesting project for sure. If I get my hands on it this is something I will definitely try out!

Thank you! The motors get pretty warm when putting them under high load constantly, such as when I drove up the hill in the later part of the video. Btw I've measured that slope at around 35° in the steepest sections. So far I haven't had any issues with overheating or power cutouts thanks to the combination of planetary wheel hubs and BuWizz 2.0 in normal mode. When using ludicrous mode or wheel hubs without planetary gear reduction, power cutouts can occur when accelerating too fast or putting the model under high load for a continuous amount of time. Thank you! Since then I restarted the project multiple times, because there was constantly new parts available. It was quite interesting to see how Technic in general has progressed throughout the years.

Thank you! Exactly, because the upper and lower wishbones on all 4 wheels are not parallel there is a slight longitudinal movement of the CV-joints between the highest and lowest suspension setting. The driving ring holds the joints together loosely but securely, while allowing a slight longitudinal movement. You can find a pic of the underside of the model below Thank you for the praise! Thanks! Already working on it.. Wow thank you for your praise, it means a lot! Thank you! It's nice to have some kind of a baseline to start with, even though there is not much left of the official set after all this time Thank you very much! It's pretty simple actually: The motors drive the newish-type 28-tooth central differential through 20-tooth gears. The differential outputs go straight to the front and rear axle differentials. I believe you can see the most part of the drivetrain in the drivetrain render in my post. Here's a better resolution version: And here's a pic of the underside:

[MOC] '21 Ford Bronco
burak replied to damjan97PL's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Especially the front looks instantly recognizable, great job. That ladder frame looks really clean, I'm sure it has taken you a few tries to make it so simple yet elegant. I'm pretty sure that's a red 2L and a 3L axle being held together loosely with a worm gear to allow slight longitudinal movement when the suspension is articulating. Very clever! -
Hi Eurobricks, I proudly present to you my first MOC. A Land Rover Defender 110 with RC functions. This is an original MOC, which was built from the ground up and has very little in common with the official 42110 set from 2019, except for ~64% of shared parts. To start with, unlike set 42110, this is the 110 version with a longer wheelbase and true to scale proportions in 1:10 scale, which were derived from the original car’s blueprints. To accommodate this the chassis and bodywork have been completely rebuilt with realistic proportions and the iconic details of the original in mind. Specifications: L x W x H: 50cm x 22cm x 22cm (with accessories) Weight: 2925g Parts: 2853 Scale: 1:10 6 motors ~5m of electric wires ~3m of pneumatic hoses The model features full remote control of many advanced functions: All-wheel drive through 3 differentials powered by 2x BuWizz Motor and 2x BuWizz 2.0 Steering with Ackermann geometry and working steering wheel Signature front and rear LED lights Center, front and rear differential lockers with 4 locking modes None locked Center locked Front & rear locked Center, front & rear locked Adjustable air suspension Variable adjustment of ground clearance from 22mm / 2,75 studs in standard mode up to 32mm / 4 studs in off-road mode Infinitely variable adjustment of pressure for optimal suspension stiffness Realistic approach, breakover and departure angles (standard mode & off-road mode) Approach angle: 35° standard & 42° off-road (real: 30,1° standard & 37,6° off-road) Breakover angle: 18° standard & 28° off-road (real: 22° standard & 27,9° off-road) Departure angle: 33° standard & 41° off-road (real: 37,7° standard & 41,9° off-road) Auto-compressor powering the differential lockers and air suspension Automatically shuts off at a system pressure of >2.1 bar / 30 psi and restarts at <0.9 bar / 14 psi Additional auxiliary PF output accessible from engine compartment Those „guts“ stay mostly hidden and the model features a detailed and spacious interior with further manual functions: Working door locks on all 5 doors Manual system pressure release valve below the dashboard Adjustable and foldable front seats and completely foldable 2nd row Spacious loadspace Small details such as air vents, climate controls, storage compartments in all 4 passenger doors and between the front seats Additional features: Easily detachable roof panel Front and rear independent double-wishbone suspension with camber angle providing 44mm / 5,5 studs of travel per wheel Partly modular bodywork, which is attached to a rigid monocoque chassis. The model is therefore very sturdy and can unhesitatingly be picked up by the roof The suspension setup accommodates easy interchange of the wheel hubs I’ve fitted hubs with planetary gear reduction as standard, because they enable superb off-road capability Those hubs can easily be switched out for hubs without planetary gear reduction (from set 42160) to enable higher top speed. However I did find that the BuWizz 2.0 units quickly run into power cutouts when you’re not easy on the throttle. If there was a juicier power source I can image how much fun driving with those hubs would be You have surely noticed that there is a few random colors in less visible parts of the model. This is due to the model being optimized to use as many parts of set 42110 as possible (~64%), because I’ve created instructions for it. Here’s a video showcasing the main functions and the model in action: You can find a few more pictures on my bricksafe here or check out the instructions on rebrickable here I’d be happy to hear your feedback! If anyone is interested I can also share some background on the development and a few tricks of the model some time

Interesting, I got the following new info from the video: set designer is Milan Reindl we get 1 new suspension arm from the P1 here as well for the rear 4-link live axle proper steering with Ackermann geometry, although it seems a little exaggerated to me 2 standard 6.5L shock absorbers for the rear axle working door locks on all 5 doors nicer interior and loadspace compared to the defender 2x2 round tiles on the wheels are printed, but the one on the spare wheel is not
