So here's the latest project I have been working on. I am actually waiting for 5 parts to arrive (4 tiles on the "boomerang" at the bargeboards and the exhaust in flat silver instead of LBG), but otherwise it is finished. I tried to recreate a F1 car with 2019 specfications with "typical" Red Bull stuff in mind (rake and pullrod in the rear for example). I took some liberty here and there. All the freaking winglets on these cars in real life+Technic=meh. So I went for a pretty basic flow of panels and wings. Another reason I also took some liberty was because trying to find blueprints or other good images for size reference of the 2019 or even 2018 cars were hard to come by for any of the teams. Or I just suck at searching, but I'd find it understandable if it is actually hard to find, since teams wouldn't want that stuff public. 20190921_135837 by Appie NL, on Flickr Functions are: - 8 speed gearbox (used didumos' and JB70's revised Chiron gearbox again, that I made 3 studs shorter again) with V6. - HOG steering through the T-cam and working steering wheel - Pushrod suspension front, pullrod in the rear - Had to sacrifice the driver's seat for a very basic gear selector mechanism due to lack of space elsewhere. 20190921_135940 by Appie NL, on Flickr 20190921_140038 by Appie NL, on Flickr The point at which the nose goes from angled to flat is too far towards the front of the car compared to real life, as the curving point tends to be right above the axle of the wheels. I am aware of this, due to the suspension setup in that section this was the best I could do. 20190921_140228 by Appie NL, on Flickr The diffuser isn't looking too good from this angle, the only good angle is looking right into the rear of the car. Couldn't figure out a better one with the limited mounting options in that section and the diff+suspension. 20190921_140301 by Appie NL, on Flickr 20190921_140342 by Appie NL, on Flickr In case you were now going: This belly shot sucks! Got you covered! (pun intended :D) 20190921_140422 by Appie NL, on Flickr I wanted to make a similar floor at first for my Rolls too, but dropped it because I am not going to be flipping that model very often to show the belly. And having to uncover it too after flipping, would be troublesome on that model. 20190921_140610 by Appie NL, on Flickr Close-up of the pullrod suspension in the rear and my crappy DRS system. Due to lack of space to route some controls for DRS to the cockpit with a diff, suspension, V6 and gearbox blocking alot of the way, I opted for this instead. 20190921_140645 by Appie NL, on Flickr Should have angled this pic more on the cockpit, but oh well. T-cam for HOG, yellow knob gear in the headrest is to flip the gears. 20190921_140956 by Appie NL, on Flickr Since Red Bull is known for the rake they have on their cars I had to mimic that too. It's a small angle, but it's there and pretty close to real life I think. In case you wonder, the car weighs about 1.7kg.
Attika posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingGood People of Eurobricks, let me present you my latest build that goes by the fancy name of "The devil in sheep's clothing". Giving this name appeared to be a good idea at 4 am when I've finished editing the video, so now I stuck with it. It's been built in a 10 day window around christmas time undisturbed. Beside the fact that few of us have the rare opportunity to dedicate as much time to this hobby, it is indeed a honest mirror on my social life too. So be careful, what you wish for. So to the subject. It is a non motorised (pushy-pushy) supercar (ish) build with the rough scale of 1:8. And now I let the video do the fair bit of my task: So if you still here, let's talk about the details: Involves a very reliable gemstone gearbox from the hands of our beloved @Didumos69. This is the 4 speed 4wd sequential from the Rugged supercar I've made a few modifications on it. Replaced the rubber rings to shock absorbers on the gearstick-centering mechanism, but I'm not brave enough to call this an improvement. Geometric barriers made me do that. The rest of the drivetrain comes with 4 wheel drive and a V10 engine as follows: I kept it simple, one might say it's a waste of space, it could be fitted with an 8 speed gerbox easily. Or 16. But no. Old school. And ther is the steering too. Same stuff I've used in the 8880 evo. Suspension: Somewhere along the way it became a pushrod suspension, but it wasn't always that. The former setup (pic below) wasn't cooping very well with the weight of the car. Had similar symptoms like the chiron so I've started over and got to this pushrod setup above. Has a lot of advantages strong, highly adjustable by changing geometry, but has a downside. The lower pushrods -made out of connectors and 5.5L axles- are relatively easy to pull apart. Not by it's own weight, but - let say- when wheels are changed, got to be careful while puting them on. Next bit is the roll cage, but it is pretty self explanatory. I figured I need some scaffolding anyway, the connector body demands it in this size, so I went a step further and gave it a proper sceleton. One more about the roll cage. The rear wing, or spoiler. As it shows above it has a dead simple spring loaded mechanism that provides two positions to adjust. Namely: up and down. Also comes with interior. Made out of connectors of course. Don't know if it's comfy or not. One of my favorite details (one of the dumbest as well) is the armrest bit on the door. It follows up nicely to the dashbord. Gives the illusion of completeness. Also just realised that I made about 58 million pictures and non of them is catching this feature at all. Good on me. The body: It's a hell of a lot of connectors and axles. Apart from the side bits and doors it's a single layer on the whole car, yet holds itself together surprisingly well. Allthough if you choose to give it to a 4 year old to play with it, he can dissmantle it in 58 second. Hope you enjoyed, any question, don't hesitate, hit me. There wil be instructions. Data shows, it takes an avarage two and a half years for me to make them so you may expect it under the christmas tree in 2022.
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingAs soon as I heard about the competition I started working in LDD to make the most functional and realistic representation of the legendary Le Mans racing car. Here's what I wanted to encorporate: - Pushrod suspension - 6 speed sequential gerbox driven by rear wheels - KERS with front wheel drive - Working steering wheel - Detailed V4 engine - Realistic dimensions and looks And this is what I managed to create with my limited amount of bricks: All the functions I wanted to incorporate have been squeezed in this small 1:10 scale 47x18x12 cm model and more! The additional features are: - Opening doors and engine covers - Working lights - Double dual speed KERS gearboxes Here's a gif to give you an idea, just how crammed everything is inside (for some odd reason the battery box and steering M motor were not rendered): And a still picture with various color coded modules: Getting back to the real model at hand, notice the eight working lights: The rear covers can open, exposing the V4 engine and the KERS generator unit: Here you can see the rear suspension and the massive spoiler with integrated lights: I even managed to make some room for the driver's seat and the detailed working steering wheel. The orange arms with towballs are the switching paddles. The yellow handle switches the KERS powered front FWD's gears: Just like in the real one, the batteries are where the co-driver is suppose to sit: And this is how the model would look like if I had all the pieces in correct colors and some custom stickers: Oops, I meant like this And finally here's a short 1 minute video of the model in action: To finish up, this has to be one of my more crammed and densest models to date. Even though its smaller than the 42039 it uses almost twice the number of pieces. This makes the car really stiff and heavy, so driving in the high speed is a bit demanding from the 2 L motors. I also had to use a different than usual approach in the rear suspension, since I wanted the car to be in 1:10 scale. This meant I had to find a way to bring wheels closer together, yet still have drive on both axles. The rear axle uses a live-axle driveline, but the wheels are independently suspended. The front wheel drive uses two 90° gearboxes to power the individual hubs. All in all I am quite happy with it, even though it uses a bit too many different colors. It's one of my prettier models, though it may not be as pretty as the competition. But one thing is sure. It doesnt get more technical and functional than this Oh and before I forget : Oh and one more thing. If you are intrested the LDD file, than please wait for a few days for me to make a video on how-to use LDD in developer mode. The model was made in that mode and cannot be correctly opened in normal mode due to all the collisions.
