  1. I have to agree here, especially on the rear end with that wacky diffuser. Quite a few proportions are off and some curves/features were lost. Functionally, the model is great, but your previous models better captured the looks and curves of the cars you modeled.
  2. "Surprise, I'm back!" It's been quite a while since I've posted on Eurobricks, and I just couldn't call my Koenigsegg project officially finished until I made a post on here. What better way to do that than to take you along for the whole journey of the build! The Journey This project started well over a year ago - October 2015, to be exact. The Arocs' long pneumatic cylinder was a perfect fit for an accurate Triplex suspension, and that's exactly where I started. Version 1 by VKTechnic, on Flickr The first prototype had several problems, notably the 4L differential's odd geometry and the stubby wheel axles. Along with the revision of the rear axle came the first front axle prototype, which despite being very slim had problems with the suspension travel. Version 2 + Front Axle by VKTechnic, on Flickr The next logical step was to build a mock chassis and hook up some motors to test the speed. The logical step, however, turned out to be a roadblock, as I realized the front suspension was two studs too wide. Back to the drawing board... by VKTechnic, on Flickr After this roadblock came a long 11 month hiatus, during which work, school, and participation on a Formula SAE racing team kept me busy. During that time, my Facebook page surpassed 1000 likes, and BrickCon 2016 was steadily approaching. The imminent threat of a MOC-less convention spurred me to start livestreaming builds again, and with that, we saw significant progress on the chassis: Shady's Back by VKTechnic, on Flickr At this point, the front suspension was rebuilt to use the torsion of axles in place of shock absorbers, mainly to keep the assembly compact and simple. A functional door assembly and the start of the active rear wing mechanism was also taking shape, and an order of electronics from TLG finished off the engine bay. Quick update by VKTechnic, on Flickr The next livestream marked a key feature off my checklist: a remote controlled, active, top-mounted rear wing. Not only that, but the rear engine cover could also be opened to reveal the technology below. Taking Shape by VKTechnic, on Flickr At this point, I began running out of white pieces, but progress went on with any colored piece I could find. Capturing the iconic front end required a lot of creative building techniques and some compromise, but by the end of the next livestream, I saw the finish line in sight. A Unicorn Pooped on my Car! by VKTechnic, on Flickr Only one livestream came after that, in which I completed the rainbow car. Five Bricklink orders and two small LEGO sets later, and the model was displayed in all its glory at BrickCon 2016. Despite an amazing crowd response, the Koenigsegg took home no awards. Nonetheless, the final model was a massive success, and it surpasses my Mustang as my best model I've built. The Final Model Koenigsegg One:1 Photoshoot by VKTechnic, on Flickr Let's get the specs out of the way first. Full suspension, with Triplex SLA rear suspension, rear Z-shaped sway bar, and front torsion bar SLA suspension Remote controlled drive and steering, with 2XL motors for drive geared 1.191:1 and steering powered by a servo motor with a working steering wheel and Ackermann geometry Remote controlled top-mounted active rear wing powered by 1 M-Motor Opening engine bay and working synchrono-dihedral doors Adjustable seat angle (just for fun) As the specs list shows, this is my most technical model by far, and seeing all of those features working on the final product is extremely satisfying. A few drives around the convention floor at BrickCon showed very minor problems with the car, most notably the tendency of LEGO's CV joint axles to slip out of the differential. Aside from that, the suspension was very responsive and balanced, steering radius was adequate, the rear wing worked, and overall the model was very solid. Koenigsegg One:1 Photoshoot by VKTechnic, on Flickr As always, a few things could be improved. Quite a few bits of the model were "floating", i.e. not fully secured. The taillights are a prime example of this, since the only piece holding them in place was the stud end of a 3L axle with stud. This meant that the taillights were not only prone to falling off if handled poorly, but they had to be occasionally adjusted to be symmetrical. Aside from that, the roof line was slightly too flat, and the studded wing bugs me ever so slightly. Despite all this, I'm very, very happy with the final product, and to this day it sits assembled right by my build area. Koenigsegg One:1 Photoshoot by VKTechnic, on Flickr Media Coverage Despite the Koenigsegg not taking an award at BrickCon, it managed to get a large amount of media attention. I do need to begin by personally thanking Ben Dominguez Studios, a good friend and local photographer, for the professional photos of the finished model you see in this post. I myself couldn't have achieved the same level of professionalism and quality that he did, and the final result speaks for itself. The next piece of media happened at BrickCon itself: an interview with Beyond the Brick. Having this interview released to the public was my excuse for not making my own video covering the Koenigsegg's functions, since it was a very well done video! This video was later noticed by Koenigsegg's own social media team, and seeing them share the video absolutely made my night. That social media post resulted in a request for the purchase of a copy of said model, which necessitated the creation of an LDD model. Should this commission fall through, I will most likely release the LDD file for public download! While the Koenigsegg video was shared around, the model made its way to a blog I had never been able to reach before: The Brother's Brick. Seeing my model among the cream of the crop of LEGO creations of all themes just leaves me speechless, just wow. Conclusion Koenigsegg One:1 Photoshoot by VKTechnic, on Flickr This model easily takes the title of my best model to date, and I could not be happier with the result. Each bit of media attention has brought a massive smile to my face, and I think I can confidently say that my inspiration to build has been rekindled. I hope you all enjoy the model, and I look forward to your thoughts and feedback!

    [MOC] Koenigsegg One:1 Summary

    I'm away from home, but once I'm back, I'll send you a copy to look at. I totally understand your point. I've thought about it for quite some time, and I've considered selling instructions or having them available by request, rather than sharing them for anyone to get (if that makes sense). At the end of the day, it really comes down to how much work it is to create the instructions themselves, and as it stands, I'm already struggling to find time to build. @TeamThrifty sounds interesting so far, once you get a thread going do let me know.

    [MOC] Koenigsegg One:1 Summary

    I'm very hesitant to do building instructions for any of my models, mostly due to Lepin's existence. I do have an LDD file of the model, however.

    [MOC] Koenigsegg One:1 Summary

    To be honest, there isn't as much flex as there is just slack in the pieces themselves (namely, the ball joints), so there is a slight delay before the ARB starts to work. However, there is still some flex in the gray ball joints at the point where they mount to the #2 connector, which is enough to create an anti-roll effect past the flex in the system. Your Peugeot build sounds interesting though, do you have a WIP thread here on Eurobricks (or WIP photos somewhere else)? I'd be interested to follow that progress.

    [MOC] Koenigsegg One:1 Summary

    In the One:1's anti-roll bar (ARB), instead of using a long bar in torsion to transfer energy, they use the central beam (in the MOC, it's a #2 connector) in bending to transfer the energy during roll. Essentially, the Z version has flex, just in that central member. Also not quite While you're kind-of right about the 'give' of the roll bar, it's less about bumps and more about cornering. Essentially, the more a car rolls or leans in a corner, the less grip you have on the inside tires, which decreases your maximum cornering speed and the stability of the car. The anti-roll bar transfers part of the load from the outside tire to the inside (minimizing the roll), while having enough 'give' (storing energy via twisting (or in this case, bending the central link of the z-bar)) to allow the car to go over rough patches in the road and also roll a slight amount (some roll is good for mechanical grip). Hope this clarifies it a bit
  7. Starting work on my next project, which will be a lifted Nissan Xterra! Got a full set of RC4WD Rock Crusher tires (essentially the same tread as the popular BF Goodrich tires), and I've also started modeling a fully functional transfer case based around the new (to me) driving rings. New Tires and things! by VKTechnic, on Flickr The green axle is the motor input, orange is rear axle drive, and yellow is front axle. In the middle, the lavender and blue gears are for HI/LO, respectively, and as expected, the FWD can be disconnected as a 2WD/4WD switch. Fairly compact, as the geared part is only 5x5x7 studs! A couple of things are still undecided with this model, the first of which is how to activate the functions. Right now, the transfer case is actuated by mini LAs, which would mean that I would likely be using mini LAs to lock the front and rear diffs. However, there is the option to use small pneumatic cylinders, in which case the axles will be a little simpler to build (more on axles later). On the other hand, using pneumatics means integrating a pressure-regulated compressor and remote controlled valves (or a valve-pump combo), which could end up being bulky. I do have the option of manually controlling those functions, but what's the fun in that? The other undecided aspect is suspension. The Xterra I'm modeling after has A-arms in the front and leaf springs in the rear, so from an accuracy standpoint that is the way to go. On the other hand, 4-link live axles front and rear would be great for off-roading. The tradeoff with 4-link suspension would be space, as independent suspension in the front would let me cram the driveline components in front of the "firewall". TL;DR I've started on an Xterra, but I've got a lot of thinking to do...

    BrickCon recap time! BrickCon Recap! by VKTechnic, on Flickr XTerra news first. The model was very well received by the public, lots of people recognized it and even more took pictures of it. It ended up winning "Most Complicated Technic", making that the fourth time I've won that award. Apparently someone wanted to make an offer for it too, but I wasn't around the model at that moment. Exciting. Aside from the model, the convention itself was a blast. Got to hang out with Austin Harper and Alexander Holroyd, both awesome builders. We brainstormed a few collaborative builds that might be built at some point in the future...maybe after I finish the other 20 models I want to build. I also managed to pick up a few older LEGO Technic sets, namely 8466 Extreme Offroader, 8674 1/8 Ferrari F1, and 8009 R2-D2. 8466 and 8674 are most likely going to be disassembled for parts, but I've got plans to motorize R2. Gotta finish that other model first though....

    Nice rig The guy who owns the original car is a good friend of mine, so no need to inform him. Update for everyone else: I'm back from BrickCon, and I had a blast. Austin Harper, who builds some amazing motorized small scale cars (and set mods), decided to join me in the Technic section. There was only one thing to do.... BrickCon 2017 by VKTechnic, on Flickr In a few days I'll be posting a full recap of BrickCon, then this weekend I'll be taking photos of the XTerra and wrapping up the build. As for my next model, you can see it on the right side of the above picture...

    It's been slow in my workshop, but I'm still alive. Still Alive by VKTechnic, on Flickr Work's been keeping me busy, and I had a couple non-Lego projects come up. XTerra progress was slow, but I rebuilt almost the entire chassis to replace the transfer case. Small details here and there are slowly being added, and I'll probably consider this model done after I show it at BrickCon. Speaking of, I've got something special in the works for BrickCon, expect a teaser soon...

    Bricks By The Bay is right around the corner, and boy am I not ready at all Almost there! by VKTechnic, on Flickr By not ready at all, I mean that my model is 99% done, weighs enough to overload my kitchen scale, and I still need to make a spec sheet and pack. Other than that, this week has shown a lot of progress on the bodywork, only a few tweaks left to go (looking at you, red skid plate beams): Almost there! by VKTechnic, on Flickr Doors and hood open (trunk and spare tire carrier still work too ), and the interior is simple, but it does the job. Almost there! by VKTechnic, on Flickr I'm pretty worn out from building, but if anyone's interested, I'll be doing the final tweaks live on my Facebook page this Sunday at 6PM PDT. I'm in the final stretch!

    I've been wanting a subtractor that small for ages...great work!
  18. IMO not too blocky, great work! Didn't think I'd ever see those tiny tires used in an RC moc like this, but you nailed it

    Another day of progress, albeit a little slower today. Slow day by VKTechnic, on Flickr Started today's livestream with cable management, and finally got all the cables in order with the addition of a manual light switch. Then came the rough bodywork, and I finished the day with a rough hood, dashboard, and trunk: Slow day by VKTechnic, on Flickr The rear is missing two of these (in a fairly obvious spot), but that won't be for long. Slow day by VKTechnic, on Flickr Won't be making much more progress this weekend, but next week the livestreams will continue!

    [WIP] Nissan Xterra

    Today's livestream showed some serious progress! Livestream 2 Progress! by VKTechnic, on Flickr Started off today by reinforcing the front end and building a skidplate. After building the axles in blue, looks like I'm out of 9L liftarms in that color, so time to order some more! Once the front end was done, I made a jig for the rollcage, which needed to be 22 studs wide on the bottom, and 15 on the top. A bit of fiddling later, and the rollcage took shape: Livestream 2 Progress! by VKTechnic, on Flickr With the rollcage done, I moved to the rear of the car. Chassis got some much needed reinforcement before the tire carrier could be attached, and I relocated the receivers in the process. Livestream 2 Progress! by VKTechnic, on Flickr Ended the livestream with a rattled brain. Since the chassis is an odd width and the rollcage is an even width (with doors on the outside of it), I need to figure out a good way to mate the two together. In the meantime, the only two attachment points are in the rear, behind the tire carrier and (nonexistent) trunk. Livestream 2 Progress! by VKTechnic, on Flickr I'll need to sleep on the rollcage mounting problem, and I'll hopefully have an answer by the start of tomorrow's livestream. In the meantime, I'd love to hear your thoughts on the progress so far!

    [WIP] Nissan Xterra

    Doesn't look like a lot, but I livestreamed on my Facebook page today and made some good progress. Progress! by VKTechnic, on Flickr In 5 hours or so, I rebuilt the front end a few times to get the winch installed and working, reinforced the transfer case, and got the majority of the bumper assembled. Going to be livestreaming again tomorrow, goal for tomorrow is to finish the front bumper, rough in the rear tire carrier, and start work on the roll cage that the rest of the body will attach to (the bodywork will be removable, so the structure holding the bodywork together will resemble a roll cage). Figured I should also mention that there's a looming deadline for this project. I'm planning on attending Bricks By The Bay (August 4-6), so this model needs to be done by the end of the month. A lot of work ahead!
