Lego Technic Baja 1000 – mini version of agrof’s class 1 unlimited buggy

The 50th Score Baja 1000 off-road race starts today, the best way to pay a Lego tribute to this event is to take an RC Technic car outside and see how it performs 🙂

Last week I showed you the BuWizz & buggy motor equipped version of agrof’s Class 1 unlimited buggy. Although the performance was impressive compared to the original with Power Functions, the car was a bit too big and heavy for my taste. I decided to shrink it down proportionally, and this mini version was born. It has smaller wheels, the body is 2 studs narrower, and the overall length is proportionally shorter as well.

The track width did not change as I did not have the proper replacement parts for the steering, I’ll work on this later. The car feels quicker, although due to the smaller wheels some obstacles can be problematic. The color scheme is not the final one, I had to use what I found in my boxes 🙂 I’ll work more on this car later as I really like the sturdiness and the performance. And now, pictures!

agrof’s class 1 unlimited buggy on steroids – Lego Baja 1000 race car with BuWizz & Buggy motors

The 50th Baja 1000 off-road race will take place next week so I wanted to create a Lego tribute video to this fantastic event. The best vehicle to choose was agrof’s class 1 unlimited buggy which is a great build, highly recommended to everyone! As usual I made some modifications, the car is upgraded with 2 buggy motors and 2 BuWizz units. It also has 2 SBricks added so I can swap the BuWizz units with Lego battery boxes. My version lacks the fine details of the original vehicle as I was afraid to loose parts at high speed 🙂

Many thanks to agrof for the opportunity to see his car and for his help making this video.

You can find the original build here with instructions:

You can find below some images of the car and the description of the changes I made.

Obviously the biggest change was to swap the 2 L motors with buggy motors. To integrate the buggy motors I had to rework the rear suspension as well. The IR receivers were replaced with SBricks.

Lego Technic 41999 4×4 Crawler Zombie Hunter mod

This car was created for my Halloween stop motion animation. I had a 41999 black and white replica built from a 9398 set with the big power puller wheels. I also happened to have a big box of Bionicle parts that were ideal to turn the car into a proper zombie hunter. I did not want to modify the original chassis if possible, rather adding some extra functions. I added a spinning blade to the front, alternating side blades powered by an M motor, and a rear spinning swatter / mallet combination powered by another M motor. Here are some additional pictures of the vehicle:

Lego Zombie Hunters – halloween brickfilm

A spooky Lego animation with zombies, vampires, mummies and a heavily armed & customized Lego Technic 41999 4X4 Crawler.

The idea was to use my custom-built Lego Technic 41999 4×4 Crawler and a huge box of Lego Bionicle parts and have some Halloween fun 🙂 There are 3 custom motorized functions on the crawler, the spinning front blades, the alternating side blades and the rear spinning swatter / mallet combination. There are 2 manual spring activated blades in the front as well.

Obviously no Lego zombies were harmed in the making of this video 🙂

Fastest Lego RC Technic car powered by BuWizz – speed record breaker over 40 km/h

A couple of months ago I saw some guys on the Eurobricks forums trying to build a Lego RC car that can go faster than 40 km/h. Although I don’t have a properly working old Technic RC unit with the remote (somehow I have only faulty ones), I have the necessary amount of buggy motors and 2 BuWizz units, so I had to give this a try 🙂 The whole process turned out to be much-much longer than I expected, but at the end it was a success 🙂

I spent several weeks creating, improving and testing the car. The basic idea was to use 2 BuWizz units, 4 buggy motors and 4 Technic motorcycle wheels and to add only the minimal amount of components to create the lightest and fastest BuWizz powered Lego Technic car. It had to be solid enough to survive all the crashes during the tests and record breaking attempts.

I had several tests at various locations until I found a proper track and the final configuration of the car was created. During this time a lot of parts had to be replaced as the axles were bent after a couple of runs.

The car does not have a conventional steering to reduce weight. For the speed runs only small adjustments are needed, so the direction of the car is controlled by the speed difference of the wheels – there are two control sliders on the phone for each side of the vehicle.

The speed was measured with the on-board GPS unit. The car was controlled mostly with my phone, but for the fastest run I was using an iPad (longer range). Even like this at full power the car ran out of range very quickly.

I think it would be possible to go even faster with this car, but that would require a completely flat surface and a chase vehicle to ensure the controller stays in range. Maybe another time 😉

Lego Technic 42069 rc mod with wheels – partial building instructions

Since I received many requests again to provide instructions for the wheeled speed recorder Lego Technic 42069 Extreme Adventure RC mod, I try to help you and took a series of pictures while disassembling the model.

Please note that this video is far from being a complete guide – it shows how to build the 2 axles with the 4 buggy motors.

Fastest Lego Technic 42069 RC mod with wheels & 4 buggy motors

This is my third and last Lego 42069 Extreme Adventure remote control mod. After the Superleggera mod I did not plan to create another one but I was convinced by some comments on my YouTube channel (thanks for the tip!). Although I really liked 42069 on tracks, I realized that the top speed was limited by the construction so the 4 buggy motors could not show their full potential. I removed the tracks and added the wheels from the 9398 Crawler set.
The pickup-style body was kept from the previous mod to ensure the car is as light as possible. The axles were rebuilt completely to fit the buggy motors and the wheels.

Mercedes AMG F1 W14 Speed Champions digital moc

Lego has organized recently another Rebrick contest with the Mercedes AMG Petronas F1 Team – the goal was to create the F1 car of the future. I wanted to create a car that looks somehow futuristic but looks like an evolution of the current cars, and represents the color scheme and the logos of the team. As I do not have too many non-Technic bricks I decided to create a digital entry. I started to build with LDCad, that’s the application I’m more or less familiar with. I started to sketch some ideas but the summer holidays came so I forgot about it. I only realized the deadline 3-4 days before it arrived, so I had to act quickly 🙂 I finished the build in LDCad, but as it does not offer any rendering abilities I had to look quickly for a solution. The Ldraw-Povray connnection was not that easy to figure out in such a short time frame, so I had to look for something else. I considered rebuilding my car in Lego Digital Designer as there are multiple good rendering options for the official app, but unfortunately I used some pieces that are not available in LDD.
