What a project, great job! Must have taken a lot of time and effort, thank you for that. This should help a lot of people in the following years. Just make sure they know it exists :) (advertise it somewhere) I hope you find time to finish it completely (or at least get someone to help you with it) considering you're going to LEGO soon (congrats once again for that).

Mini Trophy Truck V2 V1 was quite a good model, even getting 3rd place on the 2025 BuWizz Gathering, but not good enough. So as I usually do, I had to make a V2 to fix some things. Specifications and features: powered by a BuWizz 3.0 Pro driven by 2 BuWizz motors with total gear ratio of 1.4 steered by a PF servo motor front independent double wishbone suspension with ~3.5 studs of travel and 14° of caster rear live axle suspension with ~4 studs of travel interior with one seat and a steering wheel sturdy body flat and completely covered underside and wheelwells place for a pair of PU LEDs Now to compare it to the V1. First thing I changed was that I moved the axis of rotation of the rear suspension one stud lower to have more effective suspension travel. That has allowed me to run a bit of sag for better suspension responsiveness. I had to also have one more pair of gears to get the motor output lower. I decided to upgear before the axle to stop U-joints from exploding and to minimize torque twist. It is effective, although it doesn't "look" better because of the aforementioned sag. One more thing I did in the rear is improve the construction of the rear axle, this time interlocking most of the things instead of stacking halfbeams. Changes in the rear have resulted in a 1 stud longer model, which I combated by using a PF servo motor reducing the length back by 1 stud. Replacing the steering motor also eliminated the possibility of annoying bugs associated with PU motor calibration and operation. In the front I also moved the steering rack and links behind the axle for more stable bump steer geometry, increasing the wheelbase again by 1 stud. Slightly longer wheelbase and better steering geometry have made the model more stable and easier to handle. Some of the other changes are the relocated battery for better lower weight distribution, significantly reducing the possibility of rollovers, even on tarmac. I removed spare tire for less weight. Shock absorbers are now mounted at a angle for a slightly progressive force through the travel. It also "consumes" less parts, the U-joint is less prone to breaking as well as the front hubs which pop out instead of breaking. Overall I'm really happy with the model. It is better in every way than it's predecessor and I will keep it assembled for a while (until I finish my next small trophy truck digitally :)). It will be competing at the 2026 BuWizz Gathering in the Trophy truck competition.

Very nice! Took me a minute to realise which motor is doing what function, there are a lot of gears :) I like how you packaged it though. Nice body as well. Is there a lot of slack in the steering system?

Nice little model, I like how the flames look with the lights, and minifigs are a nice touch :) Could you show how how the mechanism for the moving flames work?

Very nice. I like this one better as it is able to hide the battery in the cab, and the cab itself looks really good. Maybe mounting it on those rubber-connector-things would give it a more controlled wobble and actual suspension?

Green Purple Formula Update (V3 I guess?) First most obviously, I recolored it to give it a fresh new look using the stickers from the 42048 Go-Kart (my second ever Technic set :)). I think it looks a lot better now. Second thing I did is move the rear axle half a stud up in reference to the chassis, making it sit half a stud lower matching the ride height of the front suspension. I achieved that with a lot of thin beams creating that half stud offset. I have also made the parts holding the rear hubs a bit thinner and flexible, so they look better and (maybe) have tiny a bit of flex travel acting as suspension. That's it for now. I've been building a lot during January and winter break so when I get some free time from school I'll try making a little video and a post here as usual :)

Very nice, looks solid. Do you have some images/renders of rear suspension? Wanna see how you made it :) Also, any video footage of it driving? Seems like it would do well.. until the motors overheat from the power of 2x BW 3.0 :D

This is incredible! Great job! What inspired you to build it? Since you designed the exterior in 18th century style as you say (it looks amazing btw), did something like that exist back than?

I'm very glad you came back to building, and what a model to do it with! Just a amazing model packed with features. I like it a lot :)

It's amazing, I like the trailer steering solution. There should just about be enough space for HOG gears to go around the steering motor making it a manual and RC model at the same time, am I right?

Very nice trophy truck, like the color scheme. Can't wait for the heli, will it be around the same scale as the trophy truck?

Thanks!

Thanks! Do they? Well, I guess I missed that. They must be rare than :)

Thanks!

Arctic Trail Truck Hello everyone This is my second attempt at making a trail truck, but this time I did it better so I felt like it was worth sharing. As last time, it's a 6x6 and I plan to run it at the BuWizz Gathering. My plan was aslo to have it as a bigger camera vehicle replacing the Mini Tracked Vehicle that has been serving me for over 2 years now. I wanted to use these spiky tires as I think they have better grip on loose surfaces. I got the name "Arctic" as in the snow (I know, I'm very lucky to have snow now, especially in Croatia) it kinda looked like one of the vehicles they have there, mainly because of the orange body. Specifications and features: steered by 1x PU L motor geared down 3:1 front and rear axle steering powered by 2x BuWizz motors gearing from the motors 12:20 + 1:5.4 (planetary hub) skid steering double wishbone suspension on all wheels space for one set of PU LEDs one "scale looking" seat working steering wheel connected to the steering motor 2x working fake I4 engines flatbed - place for accessories From the experience of the Mini Offroader I knew that I needed slower gearing than that so I went with 12:20 combination while keeping independent left-right side drive as that is still allowed in the rules, although I use it more to lock one side still for tighter turns like real trail trucks than for skid steering. I wanted to use bigger fake engine parts as they are more realistic and seem to me they might last longer and have less friction. They just about fit under the motors and almost go over the middle axle and are connected directly to the fast output. Steering was also geared down 3 times for smoother and more precise operation as in my previous trail truck. Front wheels turn to about 30° and the rear to half that, so 15°. There is also a limiter next to the gearing to prevent gear racks from going out of range. Working steering wheel was connected with a few bevel gears directly to the motor and it has whole 2 rotations lock to lock. You might see I used a interesting solution instead of a axle to connect a gear to the steering wheel. That is a 1/2 pin without friction and a 3L bar going through it. I did that so I can have the steering wheel half a stud further from the small frame to be able to rotate freely. Chassis was made to be as stiff as possible without weight in mind and with smallest overhangs. I used a lot if interlocking parts between the rear 2 axles to make that area as thin and stiff as possible. in the middle I focused on having all the gears and moving parts covered for better durability. I also managed to position all the electronics somewhat high off the ground so it can go through pretty deep water. I also want to talk a bit more about the suspension. It is a double wishbone setup on all wheels with 2-3 studs of travel. I the rear I had a problem with suspending it as the hard shocks were too hard and the soft ones were too soft, both with not that good articulation. I fixed that by connecting the 2 axles by a beam and suspending the beam instead (see picture below). This way I have one side suspended in semi-pendular way. That allows better articulation and control which axle is suspended more changing the balance. I can also easily add one more shock to be able to carry accessories on the flatbed. Body is... well a box. I did put the A pillars at a slight angle and it also has a place for a set of LEDs in the roof which make it a bit better than a box. The flatbed was made to be easily removable (only 2 axles need to be pulled out). Overall I'm quite happy with this model. It looks okay, with quite a lot of functionality. It is also quite capable, but a bit top heavy. Some more photos: You can find the .io file for the model here: https://bricksafe.com/pages/N1KOLA/arctic-trail-truck Video:
