Zerobricks Posted August 31, 2015 (edited) So after 3 months of working in another town, away from my precious bricks, I am back! I had to return the 4 borrowed wheels from the fox, so I came up with an idea to make a smaller 4x4 off roader with the same amount of power. This is the crazy result: If you look from the side, you can see the model is quite short for its size, which is good for offroading. Also notice the 8 hard shock absorbers giving this beast a lot of suspension travel. There is even an interrior, which can be accessed via gullwing openable doors: I am very proud of the styling, there are no major gaps and almost no straight or perpendicular lines. Now for the performance... I found a way to harness the power of 2XL motors/wheel without breaking gears (too often that is). Each XL motor is placed on opposite sides of the swinging half axle so that their torques cancel each other out, therebye having minimal effect on suspension. The only gears capabale of withstanding such torque at perpendicular angle are of course knob gears. The hub assembly is simillar to the one used in the Fox, but with built CV joints capable of handling 2x the XL motor torque. But even so sometimes an 8 tooth gear may fail if a foreign object is jamed between gears and the wheel is blocked Even though the models tends to kill gears on occasion its still quite relaible for its massive weight of some 4 kilograms. Dimensions: Length: 47 cm Width: 25 cm Height: 21 cm Here's the video of the Jaguar in action: Oh and of course the most important picture of them all Though there's not much to see, but I like the arrangment of the components, its clean.

A Gallifreyan Cat Posted August 31, 2015 Amazing. Just amazing. Share this post Link to post Share on other sites
Edwin Korstanje Posted August 31, 2015 8 large motors for drive, your crazy man . Great looking 4x4 Share this post Link to post Share on other sites
JJ2 Posted August 31, 2015 Amazing. Just amazing. I agree with him 100%! Did you take apart the FOX to make this? also why did you use the crown gear on the winch? I also see that you didn't pull a car with this....Did you try? Share this post Link to post Share on other sites
Beck Posted August 31, 2015 Wow. I really like your CV joint. 8 XLs thats stupidly powerful. I don't even have 8 XL motors. Share this post Link to post Share on other sites
deraven Posted August 31, 2015 That's just completely unnecessary. And so awesome! Share this post Link to post Share on other sites
Milan Posted August 31, 2015 (edited) Meh, nothing special. :) Wow! I think this is in class with the Fox! Awesome work with the chassis. Edited August 31, 2015 by Milan Share this post Link to post Share on other sites
BusterHaus Posted August 31, 2015 The electronics layout is great - all the heavy parts are on the bottom. How are the CV joints holding up? Do the tan pins get worn out over time? Share this post Link to post Share on other sites
KirTech LAB Posted August 31, 2015 I like your CV-joint! Good work! Share this post Link to post Share on other sites
Zerobricks Posted August 31, 2015 I agree with him 100%! Did you take apart the FOX to make this? also why did you use the crown gear on the winch? I also see that you didn't pull a car with this....Did you try? Yes i took apart the fox for this. The crown gear is slighty smaller than regular 24 tooth gear and it doesnt grind on a nearbye support beam. Didnt try to pull car yet, seems rather controversal... The electronics layout is great - all the heavy parts are on the bottom. How are the CV joints holding up? Do the tan pins get worn out over time? I like your CV-joint! Good work! So far the CV joints dont show any signs of wear, we will see over time. Anyone interested in the .lxf? Share this post Link to post Share on other sites
BusterHaus Posted August 31, 2015 I'd like to take a look at it for the steering. Thanks. Share this post Link to post Share on other sites
AndyCW Posted August 31, 2015 Wow!! Designing lego to handle these kinds of forces is no small undertaking. I love the capability. With that much torque per wheel is there any chance of trying 12/20 gearing in the portal hubs? It also would circumvent the weak point of the 8t gear. v/r Andy Share this post Link to post Share on other sites
Victor Imaginator Posted August 31, 2015 8 XL... for 4 wheel vehicle. Man, you're crazy) And i really like this non perpendicular design, i'll study LXF if it exist) Share this post Link to post Share on other sites
syclone Posted August 31, 2015 Your creations are always amazing, but this time you made it to 1000000 stars out of 10! Love the hood design , the power,Everything!!! +1 interested in .lxf file Share this post Link to post Share on other sites
Kristof Posted August 31, 2015 I usually love your models but this I have rather mixed feelings about this. Having zero experience with new PF elements and with RC cars in general, my oppinion doesn't count very much - yet I think this is more of a show off and waste than some technic masterpiece. Maybe pushing the lego limits and destroying gears and axles have some sense that I'm missing... I don't know. it doesn't even look like it performs that well, probably loosing a lot of it's overkill power just to carry the weight, fight against the friction and deal woth flex. I hope you find some better use for that motors soon ;) Share this post Link to post Share on other sites
JJ2 Posted August 31, 2015 Didnt try to pull car yet, seems rather controversial... Ya I can understand this....... I have seen a lot of hate about "faking" pulling a car on you FOX video comments. Share this post Link to post Share on other sites
vliet Posted September 1, 2015 I am also interested in the lxf, but have to take apart my fox aswell. Share this post Link to post Share on other sites
brunojj1 Posted September 1, 2015 Yeah, this is a nice experiment again! I like your fun and crazyness and the spirit of trying out unconventional solutions very much ! The torture of plastic can get an obsession to somebody... Share this post Link to post Share on other sites
DickesC Posted September 1, 2015 Nice one! .lxf of the complete front axle would be great ;-) Share this post Link to post Share on other sites
Rockbrick Posted September 1, 2015 quite simply......Nuts! as crazy as a bag of babies Share this post Link to post Share on other sites
Lucio Switch Posted September 1, 2015 I'm happy to see you back, and happy to know that you worked! The MOC, technically, is impressive. I have to study your CV Joints, seems to be a really clever solution....and yes...8 XL motors are something crazy...and I'm not one that build small!! If I have to do some criticism....I'm not going crazy for the aesthetic, but it's a question of personal taste. Anyway great job and it's nice to see you back!!

Block_Smarts Lego Technic Posted September 1, 2015 (edited) Anyone interested in the .lxf? Mmmmm yeesss pleeeaaase I think this is my favorite creation of yours! Edited September 1, 2015 by Block_Smarts Lego Technic Share this post Link to post Share on other sites
Technic Jim Posted September 1, 2015 8XL motors for a 4 wheeled vehicle. Mental. Just mental. I also love those CV joints but can't help wondering if they woud be better (or at the very least cheaper) to use blue 3L pins? Share this post Link to post Share on other sites
vliet Posted September 1, 2015 I agree with Jim why are tan pins used in stead of blue or black or grey. Share this post Link to post Share on other sites

I hope you find some better use for that motors soon ;) It was more of an experiment if such a vehicle can be made. I am thinking of making a lighter version with only 4 XL motors using a combination of Fox's and Jaguar's suspension systems. 8XL motors for a 4 wheeled vehicle. Mental. Just mental. I also love those CV joints but can't help wondering if they woud be better (or at the very least cheaper) to use blue 3L pins? I agree with Jim why are tan pins used in stead of blue or black or grey. Tan pins have almost no ridges, meaning no friction when they slide. Blue ones on the other hand are rather rough. Thanks guys, LXF is almost done, gonna upload it tomorrow along an idea for a lighter, smaller version of the Jaguar. Share this post Link to post Share on other sites
