I love this, it has thin body and full suspension incredible.

[@bramweinreder2346]

This is definitely the way to go. It would also be very cool to see different configurations of this: - horizontal push rods (side to side instead of front to back), with an engine bay between the front wheels. - torsion bar rear suspension. - passenger cabin between the front- and rear wheels, payload above the rear wheels. (In other words, more like a passenger car but with the same efficient engineering)

very epic! one of the cooler 4x4 chassis I have seen

[@LucasDynamics]

Nice design! It's so compact!

[@ShaharShoshan]

Awesome work! thanks for sharing the project

[@willbingo]

Careful Traxxas might sue you

[@clipdump]

this is beautiful

[@technicunited]

Great!! It's like a F1 frame!

[@nak_attak]

this is really sleek and nice! and free instructions?!?!?! i think I'll have to use this and attempt to make a bac mono

[@erikjones9112]

Great job, also very impressive you managed to fit steering. I would love to see this thing with a sleek body on it.

[@olegchetcin]

I agree, unfortunately I don't have many body parts yet

[@joewood306]

This thing would deserve a scale body (Tamiya, HPI, Kyosho,...)

[@Legotyres]

This looks awesome, well done

[@alexlizogub1]

its sick, just gotta lower it 1 stud

[@williamschultz298]

Impressive, well done.

[@Spedley_2142]

Very cool but I think you need to look up Ackermann steering geometry.

[@olegchetcin]

thanks, will try!

[@PiefacePete46]

I believe a formula one car uses reverse Ackermann... the outside wheel turns sharper than the inside wheel. It's to do with slip angles and tyre temps. Not that I am saying this is a F1 car... just a really nice job!

[@sebi8124]

very nice

[@saveusfromidiocracy35]

Very well done. As others pointed out, the differential would make steering better. Which tool did you use to animate and design this?

[@olegchetcin]

I am using BrickLink Studio 2.0

[@bilsy413]

A really nice design, I've played with pushrod stuff lots. One thing I've found is you have to be very careful with eccentric loading with lego mechanisms. eg. here the shocks are a block higher than the pivot location for the rocker arm. This will add bending through the arm, through the arm pivot, through the shock pivot etc. this adds a LOT of friction which greatly reduces the function of the suspension. Hopefully that's not an issue for you?!

[@olegchetcin]

that is true, but in this case it seems to be working ok with hard springs

[@mooncake5874]

great job

[@jurekgadzinowski2895]

It would be even better if it had an open differential in the front and a closed one in the rear.

[@olegchetcin]

I agree, will try to fix that

[@jdbrickcreation]

Nice ! I really appreciate the way you use the suspensions 👍

[@jeremyschafer2978]

I think using a buggy motor with a 3 speed trany would probably make it a little faster

[@olegchetcin]

will try!

[@jwdjpajtgjm]

and more power speed i want one!

[@Edward-wk9su]

Is it possible you make rebrickable instructions please 🙏. No computer needed

[@olegchetcin]

do you mean that you don't have an option to open the 3d model on computer that is linked in the description? It is possible for me to create a step-by step instructions but it would just take a huge amount of time, they don't generate automatically from the model (well, they do but the result is almost always is garbage)

[@Edward-wk9su]

@@olegchetcin yes but can’t you make like a picture steps

[@olegchetcin]

@@Edward-wk9su I cannot promise about this particular model, but I hope to come up with a better version of it and I will try to make a pdf instruction for it

[@teamlesdiy3176]

Our company also has a 3L engine. I wonder if you are interested in testing it.

[@olegchetcin]

sure, could you link me some details? thanks!

no differentials?

not in this version, will try to add them in the future

How did you make it remote control with a camera?

[@olegchetcin]

I just attached my gopro in the front =) I have a 3x3 brick with glued gopro mount

is taht as a F1?

[@olegchetcin]

right, something similar =)

[@jwdjpajtgjm]

​@@olegchetcini like rally car or buggy

[@dudefromvillage]

No differential will cause bad steering

right, I learned from this at least =)
