The concept would be interesting, I could have used such a part in a recent build.. But this might be a problem, because if they'd make it 1mm shorter to make it usable with axle pins as you say (or pins with towballs), then when inserted into a regular pin, it might be too loose, because those pins hold bars best in the middle (right at the distance when those axle-pins stop the bar), so then it could become just a bit short to reach the middle firmly.

Great that you found the button, but can you make it consistent with all the other official set threads, something like "42207 Ferrari SF-24 F1". We don't need words like "technic" and "set" in the title, we know that it's a technic set..

Sure that is not trivial to differentiate, but I actually liked that that set had both recolored (though not sure if those existed previously). In any case, they could recolor at least one of them (probably the pin variant is needed more often). That could be a reason, though I'd still prefer a slighly different shade than a compleyely different color. But they are probably going to use it outside of botanical sets, so I don't think that was the argument..

Wanted to ask the same, same format as other threads: set number, set name

That bugs me too, especially connectors, for example the pin-pinhole and the axle-pinhole parts are often not recolored to new colors, even though they are used a lot. They just keep replacing them with black/grey.

I got more hung up on advanced technology..

Or maybe there's a bar inside the pin that connects the two sides.

That's a cool looking truck, I love the old-school vibes :) I have never seen that RC unit used, let alone in action, would be great to have a video!

Not sure how the gearbox got mixed up with the MGU-H here, even the marketing material mentions them clearly separately. I agree with @Stereo that the MGU-H is probably just going to be a gear or fan that spins with the motor or with the wheels (if it's not geared to the motor but to the exhaust system).

Nice compact model, and that front drivetrain is interesting too, I did not think it could work.. Does it fit with regular rims as well?

I have been discussing this with @Aurorasaurus during the design of this motor, and I find this one of the best possibilities for using the A2212 motor so far. With a 2700 kv motor at 12V you get 900 RPM, which is a good range for a heavier offroad model meant for climbing instead of being fast, and probably has plenty of torque. Obtaining the critical part, the planetary reduction, and marrying it with the motor itself is fairly simple. Also, I think the housing itself can be further improved by having the front part also custom printed with better mounting points, more pinholes, more like on a PU XL motor. Then the two halves could be joined together with screws instead of relying on clips, like some other designs presented in this thread before. I wonder about the difference between an 1000kv and a 2700kv 2212 motor, besides the speed. I guess the size is the same, so is it like the 1000kv has that much more torque, or is it that it consumers that much less power? I guess the slower speed has to be compensated somewhere, right?

Thanks, that's a good summary of all the replacements! As for the steering, I guess in the same amount of space, a servo could also be fitted.

I was thinking whether the suspension arms are one big piece or built from 3 parts (two identical sides plus a central short liftarm with towball socket). I really hope that it's the latter. But what do you mean by diagonals? The two sides of the suspension arm assembly? Do you think that the suspension arm is 3L together with the towball socket, or that it has 3 holes besides the towball socket? I hope it's shorter because one with 3 holes would be too similar to the existing one with 4 holes. Also, it seems that the side parts of the suspension arms are 7L, have one pinhole at the chassis end and two holes at the outer end, one of them being an axle hole. Then the central towball cosket adds two more studs, so the whole suspension arm assembly is about 9L. So the steering links may just he the existing 9L ones, but they do seem a bit more like axles, so they may be some new moulds without stop in the end. That would be really good. The new 2L liftarm part with the towball (probably has an axle hole in the far end, and is mounted onto a 2x3 curved liftarm) is used in a pushrod style suspension I guess, with regular 6L links.

Oh, that's right, not the whole model. Not sure if it's possible to share just some ideas / renders about the modification for the steering itself. Maybe you could post some renders about that part here in this thread then for guidance for those who'd like to modify it, this may be a better place for that, and that way your thread is not polluted. Up to you, I'm okay with that. I see, can also work. Did you do down-gearing? Doesn't that take up more space?

I thought it should be doable, and glad to hear you did it, thanks! I guess only the servo replacement is not trivial because of the different shape, the rest (L motors, M motors, maybe even battery) should be relatively simple. Maybe you can share it in your PF mods thread? Or you want to keep that for official models only? Thanks for the support, but I guess it's been a while since this was published.. (almost exactly 3 years now!)

Thanks for all the feedback! Indeed, that is a tradeoff, and I choose the ground clearance :) Glad to hear that there's little damage! I also observed some wear on ball joints, not just on the hubs but also on steering links. Maybe some greasing there could also help.. Thanks a lot, happy to hear that you enjoyed it!

Thanks a lot, glad you like it! Really appreciate this, glad to hear that clean chassis is becoming my signature, I do really strive for it :) Thank you, those old headlights seem to resonate with many people who had sets from that era :) Sure, give those leaf springs a try! I think they are especially great for trucks. Thanks for appreciating!

Oh indeed, I found the 3d rotating video on lego.com too, it's visible there. Weird photo angle.. But the little truck looks cool :)

Looks like an cool little parts pack, what shades of blue are those? The way the front axle is mounted on this one looks weird / asymmetric, even the spacing seems wrong (like it would not fit). Does anyone understand how that is?

Oh thanks for these photos, they look quite nice together :) Indeed, plates with bars and clips are a good alternative for hinge parts that I am starting to discover and use as well!

Thanks! No, the flex axles never fell out, the mounting of the axles is constructed in a way that it follows the arc of the axle as it bends, and I think that is key here (also for soft articulation). Here is a close up render of the leaf springs, at the outer end, they are actually inserted into a (black) axle-pin connector, that creates an L shaped mount, and as that rotates it nicely follows the arc of the flex axle. Thank you!

Nice looking truck! Interesting solution for connecting the spring to the lower towball arms! This small scale has a so much potential :) Yes I know about that heavy duty CV joint technique, I haven't used it yet but plan to test it in the future. Glad you got some inspiration from mine as well!

Hi Folks! Let me show you a build that has been sitting on the shelf for a while but I only got around finalizing its presentation lately: a Zil 130 6x6 trial truck built for the mini truck trial challenge in Buwizz camp 2024. The model is actually a predecessor of my Ford F150 built at the same scale and color. As the rules of the competition said that one can only enter with a proper truck (not a pickup truck), I had to build something new, but as I did not have much time to build, I wanted to reuse some of the chassis/suspension setup, and the small blue fender parts. Because of the blue color, the Zil was a convenient choice. However, I decided to make a 6x6 version for better traction and for the challenge of building a dual rear axle, which I have never done before. Features All wheel drive with independent rear driveshafts, 2x PU L motors 5-link live axle front suspension with coil springs Live axle rear suspension with leaf springs by flex axles and support links Linkage based steering of front wheels by PU L motor Openable doors and removable cargo bed (for more flex in trial) Simple but complete interior Chassis and suspension design When I started out, I knew I wanted to keep the motor layout and front axle design from the Ford F150, but I also knew the rear axle design had to be changed because the coil spring setup was not a good fit for a truck (too high). So keeping the motor layout, I adapted its rear end to a truck, and also removed the gearbox and its motor to give space for the double driveshaft. The bare chassis looks like this, simple and slim: Then I started experimenting with leaf spring setups using flex axles, which have been used by many (I especially like the work of @paave in this area), and looked promising. However, the existing designs I found were not completely satisfactory for my needs; they took up too much space for two axles close to each other, and they were a bit stiff for my lightweight truck (I wanted something with a lot of flex). Typical designs start out with a bent (11L) axle in a downward looking quarter circle, and then the axle bends upwards upon articulation, which gives a preload to the flex axles. I found a configuration which starts out with the flex axles flat and then bends them upwards upon articulation, which allows using shorter (7L) axles with a tighter mounting, while still having a soft flex. The rear axles are really slim, consisting of only a main beam and wheel mounts. They look like this installed into the chassis: To keep the rear axles in position, a row of lower links run underneath, and and towball arms secure it from the top. The two rear axles can articulate completely independently, the are not coupled. I am really satisfied with how this came out, it's very compact and even looks somewhat realistic. Bodywork and interior To build the body, I used a mix of technic and system parts. The blue fender pieces are quite a good fit for the Zil, and a few curved slopes around it can fill the holes. The micro panels add nice curvature to the doors, and further sloped system parts can be used for the B pillars and of course the hood. Also, I wanted to have a brick built front face / grille, which I also managed to realize with system parts built in various directions. In general, the technic micro panels and curved system slopes play very well together, I love to mix them at smaller scale! As for the interior, two small seats are perfect, and I had space to add a dashboard with steering wheel and a gearstick. Running the cables through the cabin was a tough part though.. Furthermore, besides the bare trial version, I wanted to make the model so that it can be a complete truck with a cargo bed, so I made a simple detachable one using a few large panels. A key to this is that the rear section of the chassis is low enough due to the compact suspension. Here are some more renders and photos as well. More pictures are available on Bricksafe, and building instructions are available on Rebrickable. As for the performance of the model, without the cargo bed it is really a cute little agile beast :) The two L motors provide ample power, the suspension has a lot of flex, ground clearance is also quite good for the size. Unfortunately, the turning radius is not so great due to the length and that only the front wheels are steered, which proved to be a disadvantage in the trial competition. Also, the competition allowed for bigger tires (up to 62mm) as well, which I did not max out, but wanted to use these smaller ones instead because they look so cool; that also put me to a disadvantage against other competitors, so I did not place well. But when just playing for fun and making the video, this little truck gave me a lot of joy :) Let me know how you like it! Cheers, Viktor

Really cute build, great shaping, and I love how much mechanics is stuffed in there, that transverse front engine is really neat, I would not have thought that it could fit along with the steering. Clean interior, and the convertible top is also a nice addition. Great work!

Oh, that makes sense then, it's a believable name :)
