Zerobricks Posted December 25, 2017 (edited) After a few month break it's time to get back to Lego and Eurobricks, and why not do it in style I give you the leopard 4x4: The model is a combination of the following ideas and concepts: Quite some time ago I came up with double torque tube suspension idea and now it was time to use it in a real model Claas tyres were an obvious choice due to their agressive profile and massive size. With the release of the 42069 set, I was finally able to build a model with a unique and striking color combination The final model took me some 12 hours to build and the features are as following: - Powered by 4 RC motors and 2 Buwizz - Double torque tube suspension - Independent dual drivelines - Dual servo steering gemoetry - Working winch - Working lights - Openable doors - Openable hood - Openable and removable rear cover Specs: - Width: 24 cm - Height: 24 cm - Weight: 1600 grams - Final gear ratio: 1:5 from outermost RC motor output - Total power: ~60 watts Now onto the photos: The rear trunk can be opened: There is barely enough room left for seats in the interior. Notice the different springs used to potimise suspension. The before mentioned springs give the model excellent flex: There are two servo motors used in order to keep the steering system as stiff and strong as possible: Under the hood there is a hidden winch, which is strong enough to lift the car: And the final, most important photo. Notice how the left and right side wheel drive axles use different colored joiners and bushes: And finally there is a video of the model in action: Safe to say the combiantion of the four RC motors and two Buwizzes with a low gear combiantion of 1:5 results in a model with impressive performance. As seen in the video Leopard can wheelspin all 4 wheels when accelerating on flat surface, which is a first for any of my Lego offroaders. Dual servo motors provide massive steering power and rigidity and allow the wheels to be steered into obstacles with ease. Only downside to the model is it's slightly high center of gravity cause by all the added panels and detailing. P.S. It feels good to be back Edited December 25, 2017 by Zerobricks Share this post Link to post Share on other sites
Aventador2004 Posted December 25, 2017 Good work, love the colors. Who says a guy can't like purple? Share this post Link to post Share on other sites
DugaldIC Posted December 26, 2017 (edited) I'm not sure if I'm the biggest fan of the colours or bodywork but that chassis is something mean it seems..... Very aggressive and a very cool offroader Edited December 26, 2017 by DugaldIC Share this post Link to post Share on other sites
Leonardo da Bricki Posted December 26, 2017 I remember that old topic, I wanted to try something with that suspension set-up, but I haven't had a chance. Love the design of this monster, it has impressive performance, great speed, and the color scheme makes my eyes water. Good work, and welcome back! Share this post Link to post Share on other sites
mocbuild101 Posted December 26, 2017 It's amazing what can be done when 2 BuWizzs and 4 buggy motors are combined... and when a crazy (in a good way) color scheme is added, there's not much else to say except, WOW! Share this post Link to post Share on other sites
Jurss Posted December 26, 2017 Lego approved color scheme :D Share this post Link to post Share on other sites
BrickbyBrickTechnic Posted December 26, 2017 Wow! How beautiful! I love the suspension, and the axles as well. I want to see what orange and purple would look like Share this post Link to post Share on other sites

I want to see what orange and purple would look like I wanted to use that at first, but it's not as a good combo as yellow+purple. You can see some orange, lime and purple combo here: Share this post Link to post Share on other sites
Hogwartus Posted December 31, 2017 I'm not sure about these colors but the suspension seems really interesting. Good job! Share this post Link to post Share on other sites
TheNextLegoDesinger Posted December 31, 2017 wow very nice, although i don't think that winch is very sturdy, or is it? i always use a worm gear when making a winch, this makes that the motor pulls the winch and not the winch pulling the motor, if you get what i mean. i really like how you did the rear axle, wish i had some of those rc motors, i don't get why lego hasn't made a new version of it. Why won't you go out to test is, i always go to the woods when making crawlers, although mine really crawl because i only have XL motors. Greetz, TNLD PS: liked the hamster pun Share this post Link to post Share on other sites

1gor Posted January 5, 2018 It's real monster, like some buggy / pickup hybrid on tractor tires. Honestly color combination is really cool Share this post Link to post Share on other sites

nerdsforprez Posted January 6, 2018 @Zerobricksis back! Iffy colors and looks, but terrific engineering and functioning! I love this build and its performance. One of the fastest trucks we have seen. BTW... congrats on the distinction of one of the best youtube channels..... Share this post Link to post Share on other sites
Zerobricks Posted February 4, 2019 Sorry for the bump, but I uploaded the LDD file of the model on my Bricksafe and posted the it on rebrickable. Share this post Link to post Share on other sites
