Yes. Rims from Zetros are less than 5 studs, sadly.

I love the fun and diversity of contests there. And what is more, it seems that nobody bothers so much about the look of MOCs, the most important thing are fun and their capabilities. I wish to be able to be part of something like this in Poland.

Constructive feedback is necessary if anyone wants to improve. Aware constructor knows that. My UAZ 3151 at the beginning was ugly as ... Let's say it was very ugly :P But thanks to advices from people here and from FB group it became quite a beauty (at least as pretty as old UAZ can be) and it was appreciated in this improved form.

I put together a simple frame to test motors and buwizz 3.0. Power of motors is astonishing, but I have problem with return to center steering. Front of my frame is taken from 42124, so it should not be a problem of weak construction etc. But at the current state, even with calibration, Buwizz 3.0 with L C+ motor for steering is unusable. Did you guys come across similar problmes? I saw similar posts, but maybe something has changed since then?

And I, instead of arguing if it is ok or not ok to compare Zetres to MOCs, I would sit, watch and enjoy nice prepared video :)

They are some noname tires I bought a while ago, but recently I find out, they can be based on Rock Crusher X/T 1.9" model. @Celeri Thank you. I tried to reach more people by allowing using also more available and common short shock absorbers. Also the possibility to choose between "Power" and "Agile" makes the MOC more versatile in my opinion, more useful depends on situation you want to use it.

@Mechbuilds thank you. I did it with hope, that some people will decide to build it and share their experience from testing it outdoors. I believe Hornet/Red Ant can proof itself as a capable and fun to drive off-road machine.

Of course planetary hubs are not the source of the sound. It is sound of clutch in small LA :) In case of 3xL motors and one Buwizz 2.0, yes, I experienced that in some extreme testing, when I almost blocked wheels, but Hornet is pretty light weight so it should not happen when standard, even hard off-roading is done. In case of axles, their connection points are identical, so you can switch them as you like.

Hi, Here is my take on rock crawlers – I present to you an unstoppable and fully customizable rock crawler: „Hornet”! I called it unstoppable and fully customizable not without a reason. You can find out why in the video and in extensive list of features, details and links below the video. Instructions can be found HERE, they are free of charge, I hope many of you will be able to build it and have fun playing with it outdoors as I did. Without further talk, please enjoy the video! Details and main functions: • dimensions LxWxH: 36x22.5x19.5 cm • weight: 1.55 kg • 4x4 drive (3xL motors) • steering (M motor) • live axle suspension, front and rear • openable doors • easy removing the whole body with locks hidden in bumpers • it fits Lego Technic Figure Configuration options: 1. Drive and steering • Power version: 3xL PF motors for drive and M PF motor for steering front axle • Agile version: 2xL PF motors for drive and 2xM PF motors for steering on both axles 2. Body • „Hornet” – default body, more build-up, with opening doors • „Red Ant” – alternative body, more open one, 25% lighter than „Hornet” body 3. Suspension • Four independent, clearly visible mounting points available for each shock absorber • Multiple mounting points allow to configure four parameters of the suspension and the whole MOC: - suspension stiffness (from soft to hard) - suspension travel (from long to short) - body height (from low to high) - body style (from rock crawler to monster truck) • suspension can use both long and short shock absorbers Other features (which you may or may not spot on the video): • both bodies are equipped with two seat simple interior with steering wheel and some minor details • both available bodies are prepared in a way to avoid visibility of blue pins • frame is also prepared in a way to avoid blue pins • blue pins in frame are used mostly to high light mounting points for suspension and point out the front of the frame • frame prepared to be allow easy pairing with any new bodies • frame is equipped with simple cable management to avoid damaging motor cables during off-roading • changing connections of shock absorbers to the frame is fast and easy • MOC can be easy carry on both via body or accessable handle at the bottom of the frame • center of the mass is located at the center of the MOC • center of the mass is located low, most of the weight is present in axles • drive doesn't use differentials to maximize off-road capabilities • both axles are secured with panels to protect axles and drivetrain against any dangerous objects (grass, rocks, etc) • high ground clearance for both axles even with using planetary hubs • L motors are connected to planetary hubs without any reduction – this provides both speed and necessary torque • approach angle is 90 degrees, front and rear More photos you can find HERE

I am curious how (or/and with what tool) you prepared this blueprint :)

There is something seriously wrong with prices in your country ;/ I did fast recalculation and you should pay something around 430NZ. My inner voice to me: Haha, don't be so smart, you will see how prices in Poland, when revealed, will bite you in the megablocks. (Megablocks?? I see some sort of auto correction here :P)

It is not so bad as for one day build considering the scale. But I need to point out one thing - "off road wheels" - c'mon, those wheels are far from being offroad :D And you could take some underbelly photos to show us the suspension.

I finally received my package. I haven't test unit yet, it is charging, but motors are working :) All looks very solid and profesional. I have a question for people, who also received their buwizz 3.0 Does your on/off button look like mine? It is made from rugged and LBG plastic. I am not very concern about this, but I decided to ask.

I am pretty sure it will be the first thing to improve in topic related to this set improvements. Just like in 42128.

Look at the back of the box and rear axle. GC is far from beeing nice.

I love your construction of seats. I will propably never use it, because of the scale and supercar theme which are not my thing. But the fact that your seats are beatiful and build with technic pieces - this is the great thing.

Sure, I got you. Yes, in my model I don't use diffs (because it is designed to be totally unstoppable no matter the terrain). But even if I do, the GC would not change and the max you could see on my photo would be some tips of red teeths from diff gear :) And the solution presented on the video. I believe it can allow to create portal hub, without an actual portal hub, with the new hubs from 42099. I hope you understand what I mean. But as I mentioned before, I wasn't able to test that idea because lack of old 16t gears.

@gyenesvi Yes, no tricky geometry here, and yes, the lower part of the hub is tilted inwards a bit. But this tilt is so small that fully acceptable. And about new CV joints, yes, it is some sort of drawback, because my amount of those parts is based only on 42099 inventory (new CV joints are constantly unavailable on lego store and quite expensive on bricklink - at least in my country). There is a way you can avoid CV joint and still be able to use hubs - check the video, 1:33. I did not test this solution because I couldn't find my old 16T gears :P And about the tires, there are no names tires from ali I spotted other day. But I believe that the original model is this one you mentioned.

In some sense, yes :) I apologize for kind of mysterious photo, but I still working on this project and as you can see it still needs some minor recolors and parts adjustion. But I am pretty happy with ground clearance (it is the same for LEGO tractor tires). At the picture you can see how I decided to deal with ground clearance and new hubs. Steering is done with M motor and small LA.

I hope soon I will present my rock crawler with those hubs and the solution, which shows that it is not so bad with GC with 42099 hubs. @Danifill Great functions and recognizable body. What is more, it really can drive even considering the weight.

They should use tires from batmobile set to make them less rare and a bit cheaper. And it seems they would fit better here, but we will see.

I will pick this set up, no question about it.

I am hyped and I consider this not as a part pack, but as a set to put on shelf and admire and that means something!

I did. 4 out of 10 pieces had alignment issues I contact support and they sent me replacement. And new pieces also had alignment issues :D I stopped there. It is sad that quality drops, but I will not contact support again (about this order at least).

You are great in this scale, it is clearly visible. Please continue you work since you are inspiration for MOC creators like me who prefer such scale. I will definitely back to trucks in this scale, as soon as I finish my rock crawler :D
