The video & free building instructions are published for the LEGO® Technic 42065 RC Tracked Racer buggy motor & BuWizz upgrade:
Exclusive footage of a previously unseen RC prototype of the LEGO Technic 42077 Rally Car! We took the risk to get this video & photo material for you, stay tuned for more details soon!
I was asked many times before why I do not try a “proper” RC car instead of my LEGO RC creations, so I decided now to give it a go. The JJRC Q60 6WD RC truck is a really cheap one (currently available for $30-$35), it was really interesting to see how it compares to the different LEGO RC vehicles I have.
I’d like to share with you the RC mod of the 42077 Buggy B model with 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.

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!
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.
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 🙂
A brand new type of video from RacingBrick – stop motion brickfilm! 🙂 It’s a short teaser for my BuWizz powered Lego Technic RC speed record breaker. Join my little helpers to see the final tests for this beast and see the wheels spinning over 3000 RPM!
