agrof’s ULTRA 4 Crawler Buggy – hill climb

I had a chance to test this fantastic little buggy, agrof was kind enough to give me the opportunity to drive and film his latest creation. The buggy has 4 wheel drive, it is equipped with 2 L motors and a Servo motor. It has an AAA battery box and an IR receiver by default but for this occasion I swapped them with a BuWizz unit and also replaced the wheels. The location is the beautiful hill of Hegyesd (https://en.wikipedia.org/wiki/Hegyesd), hope you’ll enjoy the video as much as I enjoyed shooting it 😉

agrof’s class 1 unlimited buggy on steroids – building instructions

I finished the building instructions for my buggy motor mod of agrof’s class 1 unlimited buggy. Please note that these are not complete instructions, the aim was to show you the main modifications I made on the car. There’s no part list either this time. I tried to highlight which part/sequence needs to be changed compared to the original build. I was using 2 BuWizz units to power the buggy motors, the units were replacing the seats in the cabin.

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.
