  1. Thank you all for the kind words! Steering rack is to the rear of the car, so the suspension will slightly toe in on compression.
  2. Alrighty, another update! Took some time today to test livestreaming on YouTube. In that livestream, about at the 18:12 mark, I ramble about my progress on the Lightspeed Transmission and do a short demo: As you can see, the concept works, but there are a few improvements that need to be made (namely, a non-human logic controller). Feel free to take a look and let me know your thoughts!
  3. Alright, finally an update. Transmission video is still on the to-do list, but I've made some good progress on the rear suspension packaging: Rear Suspension by VKTechnic, on Flickr I've had to make a few aesthetic sacrifices compared to my One:1 model to ensure that all the functionality of the rear suspension is there. Two hard shock absorbers per side should take care of the weight of the model, and the long pneumatic cylinder acts as a squat damper. Upper control arm (magenta) and lower control arm (green) are different lengths, resulting in decent camber gain through the suspension travel. Rear wheels are driven (orange) and steered (red). The Anti-Roll Bar (white) is still subject to change, but is currently functional. Next challenge is to connect all the mounting points with some sort of structure...
  4. I found pics of a Nissan in your flickr stream.

    Almost there!

    What model is this? And do you have a build thread for it?

    I'm planning a Nissan Patrol my self, and this seems very interesting. The only part that sharply separates it form a Patrol is the rear end...

    By the way, Very Nice Build!!

      This is a Nissan Xterra. I had a WIP topic here, but never got around to publishing the final model. It's been finished for a few years now and has visited 5 conventions, so I guess it's time that I publish it and move on. Feel free to look over the WIP topic in the meantime while I'm preparing final model photos.

      Thank you. Looking forward to seeing the presentation topic!


  5. No, the engineers at Koenigsegg are the ones cheating ;)
  6. The hard part with using both ends (at least with pneumatics) is that you have to be able to select the neutral precision precisely. With my current setup, I'm using one switch to control extension of two cylinders. Each output of the switch is responsible for the extension of a cylinder, and once the air is released from the line, a rubber band returns the selector to neutral. This way it only takes 4 servo motors and 4 switches to control the 7 "clutches".
  7. White car I am hoping to do a video demonstrating my prototype soon. I don't necessarily need a complex setup, but it's a good engineering challenge. Mostly for fun, but also the packaging of it ends up being actually quite a bit nicer with pneumatics actuating the clutches directly. Based on my current sketches I should be able to fit everything in. I was also already planning on adding in a compressor for pneumatic doors, engine cover, etc.
  8. Just came back from BrickCon where I showcased my model of the Jesko's Lightspeed Transmission, so I figured it's time to start a build thread. Light Speed by VKTechnic, on Flickr This will be a car built around the Porsche wheels, giving the model a scale of roughly 1:8.6. This will be my biggest car model yet and hopefully the most feature rich. Below are the planned functions for this model: 9+R 7 clutch transmission operated with pneumatics Drive with 2 XL motors Front and rear wheel steering (real car has ~5 degrees of rear wheel steer) Front and rear Triplex suspension Opening synchro-dihedral doors, front trunk, and engine cover (hopefully with pneumatics) Active top-mounted rear wing This project will take me quite some time, especially between my university studies, work, and a few other things, but hopefully starting this build will keep me motivated to build.
  9. 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.
  10. 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.
  11. 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.
  12. 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.
  13. 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
  14. Been taking some photos... Another one by VKTechnic, on Flickr
  15. Would love to see pictures of the chassis! Great work!
