Oh ok, I'll look into it Hopefully done tomorrow

Here's the topic :)

That caster angle gets way too large (or is it small?), it'll be very unstable when driving, as in not willing to go straight forwards. Should probably lower the suspension a lot or redesign the front axle to not be dissapointed when it's all finished.

I really recommend flex axles, 7l are perfect in my opinion. You can adjust the stiffness of them depending on their connection to the chassis too. I'd say go with leaf springs

YES! Lada Niva it is! I had a really hard time finding anything short enough, but the Niva is just perfect in terms of dimensions.

@LvdH Yeah, that would work, maybe even a series 1, 2 or 3?

Ok, let's put this thread to some use. Here's my new WIP, a micro-sized (is it micro or mini?) 4x4: What body should I build? by Pego's Legos, on Flickr What body should I build? by Pego's Legos, on Flickr What body should I build? by Pego's Legos, on Flickr What body should I build? by Pego's Legos, on Flickr The steering is very special to make it fit under the L motor, a servo to a linkage system to the axle. It is a little sloppy, but very usable. What is not usable are the tires. They have of the worst rubber, and are useless offroad. I already found a solution, model team tires as rims and some old tires on top, with much better rubber and grooves. The question then is what body should I build? I want something fairly simple, light and small, so Suzuki Jimny and Samurai came to mind. I don't know if I want to build a fourth one of those though, so something else would be nice. 17 stud wheelbase 13 studs wide body, 15 at tires FJ40 doesn't work, as its body tapers inwards

Thanks! Sure, a little more flex could work, but I personally think suspension flex is over-hyped, you don't need 45 degrees of flex for it to be good. Mine is arguably however a tad too stiff, but there isn't much I can do. The front leafs are how they are, but the back has some tuneability. I wouldn't loosen it up, as that would sacrifice stability greatly, and to be fair, driving skill can almost always compensate for the flex, but it can't when you are hillclimbing. Still, feel free to argue with me on this one. Haha, I wouldn't call this one small, there's almost room for a smaller rock crawler under the seats

Hello Here's another Samurai, but this time a long wheelbase version. Even if it looks similar, it is not at all related to my previous Samurai, as this one has completely new axles and an XL motor to power it, while an M motor steers it via linear actuator. This one even has room for a midifigure! It has leaf spring suspension, and relatively little flex, but I like it, as it eliminates torque-twist too. The gearing is also very slow, an XL geared 5:1, but this makes it very controllable, and I enjoyed diving it much more like this than with faster gearing. I did try to make a gearbox work, and it did fit, but it just didn't hold up to abuse that well, so I took it out. I'm very happy with the front axle, as it uses the wheel hubs, but still has lots of clearance and doesn't have much camber. It has very precise steering too, thanks to the mini linear actuator. It has lights in the front too.

@JJ2 Yeah I had to make the suspension like that for it to fit. I like these tires too, but too bad that they become unusable normally.

We finally got some nice snow here in Finland, so here is some footage from that: I also made the tires wider and flatter by pulling the tire out to the edge of the rim, making it perform much better.

I advise not to use the wheel hubs on this one, they would explode immediately under the torque from a couple kilos on 81 mm tires. Use portal axles instead, prebuilt or built-up. They might be bigger and more restrictive, but at least it will move. I like the design of the axles though, but they aren't the right ones for the task.

Yes I'll make an LDD file From various sets, the tires are the 81.6 mm ones, and rims are unimog tires rim. The tires are stretched on, and they are now unusable on the original rims

Thanks guys! Yes the suspension system worked quite well, it's simple and robust. And no the xerion tires wouldn't fit, they're about 25 mm too big
