It is instantly recognisable and I am Impressed with your shaping. However, I also think that this time the wheel arches built in this way don't work well and for me they mess up what is otherwise a really brilliant MOC.

If putting an axle through a part that is designed to have an axle put through it is "too much stress" then my bad. I accept that age can play a part, but some of these new parts break far too easily in my view. I guess if you still have some parts from the 90's like I probably do, they are bound to start getting a bit brittle by now. Perhaps that is the problem. We have been playing with our Lego for too long?

Correct. These ones NEVER seem to break for me

Yes. I have plenty of these broken parts. It is pretty annoying. Also annoying are splitting axle hole connectors parts.

Done already! And with some good MODs. I agree that the wheel covers really enhance this model.

I have finally had some decent time to get my Lego out so have been playing with the new gearbox parts from the Chiron with the aim of installing a new gearbox into my last supercar I have ended up with a 6+N+R sequential gear box. A nicely working return to centre gear stick, adjustable seats upgrade and completely redesigning the chassis. I am thinking about some changes to the body work as well to differentiate the MOC but not quite at that stage yet. The shifting mechanism evolves from the recent one discussed in topic The gearbox looks to reduce friction as only half of it is driven at any time. I probably need to build a stand alone version to show how it works properly - when I get time. The step ratios between the gears are also fairly realistic as each gear doesn't share its ratio with any other gear further down the sequence. Gear Step Ratio 1 2 1.667 3 1.333 4 1.250 5 1.200 6 1.200 Shakey (hand held) video that shows the sequence https://bricksafe.com/files/PvdB/mocs/ultimatum-gtr-s/VID_20190407_115614168.mp4

Wow you are putting that together fast.

I am interested to see this car. What era does this car originate from??

After a lot of testing I believe that the design of the rachets that you proposed does work better than the solution I put forward with regard to the fact that your version requires far less tension on the rubber bands, and is thus far more reliable under load. I sorted out the blocking issue by swapping out one of the pins. It must have been very very slightly bent as with the new pin every thing works fine. This is a great modification of the larger knob wheel sequencer.

I think you have answered the question here. I think that even running the band between the support and the ratchet lever can give that important level of precision needed for your version. I was a bit lazy with the band placement when I built it!! With my mod, it doesn't seem to require so much precision, and surprisingly while it does require tension, its not as much as I expected. You can just throw it together in a fairly loose experimental assembly without any tweaking and it works.

No idea why it kept catching, but I played around with it quite a bit. Ignore the rough and ready construction below, but it shows the modification. The tension should be provided in a slightly more refined manner as well! but this was good enough in experimentation.

I had a problem with the shifter when I built it. It works well in one direction but keeps catching and getting stuck in the other direction. I made a modification to the ratchet mechanism which seems to hugely improve it. Will post a pic later.

Well that is an absolute beast. You have gone all out on this one and I really like the styling. I am quite interested to see some of the insides.

That somehow looks way better than a standard Chiron in my opinion

This looks great. I am going to have to build the shifter to see if it works on my new gearbox. I am also working on a different 90° stepper at the moment but it is not reliable yet.

I really like it. The chassis looks great and the bodywork is really interesting. Great model

Happy holidays and new year everyone. Nice MOC Paul. I hope you all got some good presents for Christmas.

Lack parts??? I am not sure what you mean.

Cheers @Lox Lego I agree, @KD123 took some nice photos. As for my next build (MOC) - it is going slow as I have been busy over the summer. And now I may have to build the brilliant Mclaren P1 from Brunojj which will add further to the distraction

I wondered where you had got to Grum. Glad to hear that you are feeling better again. Your earlier descriptions of the build inspired me to download the instructions and start building this truck as I have never built it. Good to see it finished. It looks really good.

I agree, it is impressive work to reverse engineer such a complex model, but good that you managed it so well as we all get to see this great MOC again.

I am also not heavily into building 3rd party MOCs but every now and so often it is worth a try purely because it is so interesting seeing the techniques of other builders - which are all a little bit unique. I find that seeing this variety has helped develop my own technique. Having experienced this, I find building Lego's own models which seem to follow a similar construction style a bit boring these day, so I get my 10 yr old son gets to build them - even the Chiron!!!! I just get him to show me any new interesting bits along the build - Win - Win situation for me. However, I stray way off Topic! LvdH is right, the "knock off" brand seems incapable of doing a decent job on the more complex MOCs so good luck to all the "knock off" fans who spend their hard earned cash on their cheap imitation rubbish.

Taking into account a few of the later comments - I had heard that Lepin did have a deal with one particular MOC builder, whether its true or not I am not sure. When I build a MOC and it comes out well, then the furthest I would have gone in the past would be to present it, and perhaps create a digital file for myself to preserve the ideas and an image of the MOC into the future. Creating instructions is a task that I would never consider doing for my own sake and I am sure this is the case for a few other MOC builders. If the recent and brilliant Mclaren P1 had been presented without instructions I can garuntee that Brunojj would have been in-undated by requests to create them. Thus comes a strong justification to charge for the time it takes to create the instructions, not forgetting the time it will take in future providing technical support when required. Of course there are a few builders who are creating models purely to sell instructions, this is fine in my opinion but is different motivation for building.than I have.

My view is that I am quite flattered that my model was made into an official knockoff brand set, even though I am not particularly happy with the fact that the model ideas was used without any recognition or reward to me the designer - in effect stolen. While I am a fan of Lego and would never dream of mixing it with an alternative brand, I accept that the alternative brands now exist and even seem to be growing. As with many young companies, the methods employed by some of these alternative brands are not what many would call legal or morally correct, and in this particular market this is much more obvious. (a small start up tech company using cracked versions of software is much less obvious but similar principals) In my view, from the perspective of MOC designers having their ideas stolen, Lepin could solve all of this by offering a small royalty and designer recognition. Even though I might not approve of Lepin's current practices, if they are going to use my idea and I can't stop them, then the above would at least solve the issue between Me and Them. Accepted they still have an issue with Lego parent company!!!!

A pretty and stunning replica. The bodywork is amazing.
