Lego Technic 42078 Mack Anthem proportions

Last week we received the pictures for the complete Lego Technic lineup for first half of 2018. I have to say I really like the 42078 Mack Anthem truck, it’s got plenty of details, tons of pieces for a fair price and a B model that could easily be an A model on it’s own. I read a lot of complaints (as usual),Β  and one of them is about the proportions of the truck. I made a quick comparison with the real thing:

Please note that the perspective of the 2 photos is different and it is a very quick and dirty alignment. What I can see from this:

  • on the Lego version the nose is longer and the curve of the bonnet is not that significant
  • the rear wheels are 1-2 studs too close to the front

It is very important too see that this is not a scale model but a Lego Technic interpretation of the Mack Anthem truck, with all the limitations of the system and the available pieces. I think the designers did a very good job, and as always – it’s Lego, you can build it just the way you want πŸ™‚

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 πŸ™‚

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 πŸ™‚ 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 πŸ™‚

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:
https://rebrickable.com/mocs/MOC-4247/agrof/class-1-unlimited-buggy/

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 rearΒ 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 πŸ™‚ 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 πŸ™‚

Building instructions for the BuWizz powered speed record breaker

I received many questions and requests to provide details about this car, so I created this step-by-step assembly video and uploaded the part list to rebrickable.

Let me know if you build the car or something based on this version, I’m really curious how fast can you go with it πŸ™‚

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 πŸ™‚ The whole process turned out to be much-much longer than I expected, but at the end it was a success πŸ™‚

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 πŸ˜‰

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.

The car is driven by 4 buggy motors and there’s a PF Servo for steering. It is controlled and powered by 2 BuWizz units. It became surprisingly fast, I was curious so I added a small GPS tracker to measure the top speed – you can check the result in the video πŸ™‚
