Thank you. I know that here in the forum such crazy things are quite taken with a certain amusement, if they are well done. So I was really looking forward to sharing this MOC here.

Congratulations to all of you. Every MOC impressed me! Word!

Another advanced one is the Motorcycle carrying an engine in its sidecar. The front wheel is steered via virtual pivot point steering. And the sidecar wheel is connected to it. The steering is seasoned with some hint of Ackermann. The engine is connected with a gear grabbing into the rear wheels. _DSC3955ready by Pow, Flickr MotorcycleAction by Pow, Flickr

That is possible. This mock up is meant to show the principle. i've tested it in a much wider (9 studs) build. @stevendejong What could be interesting for you is the steering knob. thanks for the calculation In my larger build i used the L-shaped 4x2 Liftarm. This image is just a quick mock up, as i wrote.

Another approach with ackermann (untested mock up) It builds up pretty high It needs some explanation: I have wanted to introduce this modification of the virtual pivot steering to you for quite a while. Now I think it fits, because the topic is being discussed again and my version brings some useful improvements. So I quickly clicked together a 4 stud wide version. One improvement is the "Ackermann mimicry", which is easily realized by moving the front pivot pin further forward. The other is the possibility of a knob control. In the example picture this is indicated by the long black axle with white angled liftarm, which pushes on the extended steering arm (light blue 5 lift arm) via a the orange liftarm. The long lever results in a very smooth steering behavior that is easy to control. studio-File: https://bricksafe.com/files/wop/studdstuff/4-wide-virtualpivot-steering-with-ackermann-prototype.io

A number of smart ideas have been incorporated. For example, the hinges for the back doors. <Joking mode on> The wheels are nice and wide. Good that there were already first tuning attempts in 1928. <Joking mode off> No seriously - This is a really nice and well designed model.

& Thank you

Thanks for sharing your many information. to fix the unwanted change in the caster angle, would it be possible to use such modified swing arm design (just a fast mock up)?

Thanks for your review. The fact that the instructions are only delivered digitally has so far kept me from building the B model. But after your review I will make up for that in a timely manner.

looks promising. i am curious how it continues and look forward to the videos as they are superb!

@Lipko Your creatures are very well made. Good luck to all participants! EDIT: Is that really an official TLG Event?

@vergogneless Thank you. But i don't know if it's terribly or ingenious ;) But at least it's following the rule: "something is finished when nothing can be removed." -> This steering is definitely finished. ...and no, I am still not satisfied with it.

Gluing: No brick was harmed during build. There is no glue involved. and the Slope: You'll be surprised how simple the solution is.... And I really wonder why you don't see that more often. Oh, I'll just throw in the promotional video.

The structure is nice and tight. And looks great. But if you move the steering linkage in front of the wheels like in the case of the car, don't you automatically get an anti-ackermann geometry? So the the curves outer wheel steers more than the inner wheel?

You know the rule. If a set has wheels, or parts that can be used as wheels. Then at least one F1 car must be built! I built one. Sorry! _DSC3525ready by Pow, Flickr _DSC3538ready by Pow, Flickr _DSC3539ready by Pow, Flickr ...at least it has a lot of different angles. Have a nice week.

@vergogneless Here is a third photo. It's pretty self-explanatory. What i like about this mechanism is that the pivot point of the wheels looks more natural compared to legos default steering mechanisms. where the wheels move forward and backwards a lot. The blue liftarm with the brown axle is connected to the motor at the front. It pushes the steering arms. The rest is just unholy wizardry. And yes it has a lot of Anti-Ackermann! But that can also be fixed. And if you provoke heavy load changes say push the steering very hard more weight goes into the curves outer wheel and the steering becomes sharper. Plus Anti-Ackermann is used in very fast cars (NASCAR for example). So perfect for brushless motors. Any questions?

As i am a in a hurry i just post two pictures of the front suspension. a few words on how it works will follow on monday. Or you find it out yourself

small and simple. I like that! In that scale you can easily integrate a shock absorber - getting rid of that rubber band. I build something very similar like your car last year. ...Just for inspiration. The finished product is on rebrickable: https://reb.li/m/131895

Thanks for sharing all that knowledge. i like it! what does low cost mean?

They did a relatively good job with the pins. nearly all pins connecting the (green) panels to the car are in black. But what would important to me is the amount of gears. And whats a shame: it has 100 parts less then the bugatti but costs 3 Money more.
