If your part selection is that limited, going for a not-so-stable floating axle would probably be your best bet in terms of steered and suspended axles. You will only need a differential and a universal joint (+beams and connectors) to make it work

hey all, thank you for the feedback, the good, the bad and the ugly (especially the ugly :d ). I think I forgot to mention it in the write-up, but yes the door braces… well suck, and the only reason the doors can stay up are the door “locks” on the chassis. The suspension is also somewhat meh, they do work but do not nearly have the bounciness I see in other mocs, and as brunojj pointed out, this is probably due to the small liftarms I used. You can find a partial picture of the underbelly in the bricksafe link. Thank you again!

Thank you all! Yes, I do agree that the roof is a bit too high, though if I recall correctly, it was only by 0.6th of a brick, so I didn't see it fit to lower it by a complete stud. Yep, the difference between the ratios is not much at all (I'm going to be honest, I never cared enough to calculate them, when I saw that they all had different ratios, that was enough for me) I'm glad you liked the read! Like I said, I'll try to post a video showcasing the functions ASAP

After many years of work, I am proud to present my take on the McLaren 720s in 1:10 scale. Lego 1:10 McLaren 720s by @tiledfloor, on Flickr It took 4 different iterations of chassis to get to this final version. I started this project with (almost) no experience in Technic MOCs, so I expected this to be the case. The first version was in 1:10 scale, had an 8-speed gearbox (which couldn't shift reliably), was wobbly as could be, and looked abhorring. The second version was in 1:8, -for some reason I thought that my first technic MOC could be THAT large without encountering many problems- I quickly realized how wrong I was. The building process was infinitely harder than in 1:10 due to the required stability and stiffness and added connections between components. This version had a really unique mechanism that I hadn't seen anywhere else though: adjustable drive modes, thanks to small linear actuators controlling the stiffness and travel of the shock absorbers. (you can find a video of the mechanism in action here:) Suspension with adjustable stiffness by @tiledfloor, on Flickr This version also had remote door controls, but after many problems regarding part count, sturdiness etc. I quickly realized that 1:10 was a better suited building scale for me. And so came the final two iterations, the first was almost a 1:1 copy of Dirk Klijn's mp4-12c, but after completing the chassis, I dismantled it to create one that allowed me to add a couple more functions, but I can safely say Dirk's model was the one that inspired me and taught me the most throughout my journey, along with Bruno Jensen's P1 and Charbel's 720s. And the final one was the one that I was finally satisfied with… Lego 1:10 McLaren 720s by @tiledfloor, on Flickr I wanted it to be completely modular, meaning that every single mechanism could be separated from all of the surrounding components. This was the most difficult part of the building and designing process. To achieve this, I settled on a transverse 4-speed sequential gearbox (IIRC, it was borrowed from Charbel’s 8 speed design), a custom made v8 which would sit as low as possible to allow for some detailing on top. The most difficult part of the chassis was the one-piece carbon monocoque also present in the real deal. Lego 1:10 McLaren 720s by @tiledfloor, on Flickr It had to be stiff, allow for two functions to pass through it (gear shifting and active aerodynamics), and still fbe as close to the real McLaren as possible form-wise. Lego 1:10 McLaren 720s by @tiledfloor, on Flickr The modularity also presented many problems mainly relating to the longitudinal stiffness, and I must admit, I wasn’t able to solve all of them, which resulted in a chassis that bends a bit when the suspensions are activated. Though overall it does generally behave as a single-piece chassis, and driving it around feels stable. Lego 1:10 McLaren 720s by @tiledfloor, on Flickr The rear axle is perhaps the most compact, stable and best looking part of the chassis imo. Lego 1:10 McLaren 720s by @tiledfloor, on Flickr After the chassis came the bodywork. It has many, many, MANY illegal connections that bend and induce torsion in long beams and panels. But overall, I am actually quite happy with the way the body turned out. The lines are as smooth as I find reasonably possible in this scale, and the proportions are mostly accurate. The car sits as low as I wanted it to, and has many of the original curves and lines that make the car recognizable imo. (most importantly, it passes my “squint test”, where if I squint hard enough it is indistinguishable from a photo of a real 720s.) :) Here is a rundown of the functions present in my model: -independent suspension on both axles -steering wheel/HOG with an acceptable turning radius -folding display in front of the steering wheel -adjustable seat recline on both seats -opening hood (half) and doors (though the doors require a bit of a wiggle to get them to sit right) -airbrake connected to steering -fake v8 -4 speed sequential gearbox controlled from the cabin (via turning a knob) -modular chassis -modular bodywork Lego 1:10 McLaren 720s by @tiledfloor, on Flickr The rear was very difficult to recreate due to the many intersecting curves and the large space the active airbrake mechanism takes up, but it’s the part of the body that I’m most happy about. Lego 1:10 McLaren 720s by @tiledfloor, on Flickr here you can see the airbrake in action, notice that the front wheels are in a “steered” position and that the spoiler is raised compared to the previous photos. And a final shot of the rear: Lego 1:10 McLaren 720s by @tiledfloor, on Flickr I am going to upload a video showcasing the functions whenever I can, in the meantime here is my bricksafe for a couple more photos: https://bricksafe.com/pages/tiledfloor/mclaren-720s-110- I eagerly await any and all constructive criticism. With this being my first full technic MOC, as well as my first scale model, there are plenty of things I can learn from you guys. Thanks!

The pink blades of grass provide some really cool contrast with the trans-neon yellow pieces. As a fan of the Power Miners theme, I'm really glad to see a few pieces from the giant monster utilized to great effect.

Looks really good! Though a small suggestion: Perhaps building in SNOT for the rear danger stripes (the ones in black and yellow) would work better, though I'm not sure if the internal structure could support it. It would add some detail and would look a bit better in my humble opinion.

The small ingots and the books and scrolls add so much detail that it's almost unbelievable, not to mention the "shooter" bricks on the base... Great work.

The tree on the right reminds me of some old Star Wars MOCs in crazy biomes. Funky!

Wow, one of the best system builds I've ever seen! I especially like the archways on the bottom right, they reming me of a modern warfare 3 multiplayer map. The small wooden supports sticking out also add a very special flavor of realism to the build.

I'm not usually a fan of the look of front-engine supercars, but this one looks really good! The only thing I'm not quite sure of are the dark bluish grey side vents, I can't help but think that black would work a bit better. The chassis looks (and functions) phenomenally! One of the functions that always manages to woo me the most is adjustable ride height, and I think your mechanism is pretty much perfect at this scale! The roof, even though it is quite flat, fits the look of the car perfectly, this really does give the feeling of a high-performing multi-million dollar streetcar. Awesome work!

The front looks almost perfect imo, but the rear stacked wedge pieces don't quite work for me, maybe a small panel faring (no 22) would work a bit better? Also it is at times like these when I wish the most that LEGO made much smaller battery housings for their RC motors. excellent work regardless!

Wow, this is really amazing. This may sound a bit silly but my favorite part is the cabin, the size and the smoothness of it provides a nice counter to the rest of the model. The winch looks like it was a nightmare to design, but it definitely turned out great.

The domed roof on the main tower is really quite something! I also especially like the different shades of brown you used on the walls. Great work!

This is the best supercar MOC since brunojj1’s P1, IMO. Superb flow and amazing paneling. The simplicity of the chassis elludes me, how can it be so simple yet still carry so many functions?... Since I have been working on a 720s of my own for some time now, this really sets the bar high, I don’t think I can reach it
