I would like to present you the motorized remote control mods of the LEGO® Technic 42077 Rally Car. There are two upgrades available, 2 wheel drive and 4 wheel drive with additional extras.
I’m starting a new Lego Technic tutorial series focusing on the Power Functions parts and other electric components that can be used to make a Lego model remote controlled. I’ll try to make it clear and simple, so don’t expect immediately some advanced RC trickery – the aim is to help the ones who are not that familiar yet with the Lego RC world.
The Lego brick turned 60 years old, so I thought I need to celebrate it with a fun little Technic creation. Nomen est omen – I created a racing brick 🙂
I made my first quick proof of concept rc mod of the Lego Technic 42078 Mack Anthem truck to see which motors fit and how in the chassis using some spare parts I had. I did not plan to release any instructions or images about it as it was just a test and I will do a proper RC mod sometimes in the future.
I would like to wish you all a Merry Christmas with this video and thank you for your support!
The Lego Technic 42078 Mack Anthem received additional rc functions with the lights and the motorized trailer, controlled by 2 SBricks. The light sequences of the container are also controlled by one of the SBricks. The trailer has 2 Power Functions L motors built in. Also tested with M motors but they could not handle the load. Please note that this is a test RC mod, so there won’t be any instructions for the time being. I’m planning to do a proper rc conversion and I’ll share that one in details.
The upgraded container interior is based on the following alternate build of 40223:
Lego Technic 42078 Mack Anthem review updates and RC mod with SBrick
– Updates/correction of my review
– RC mod with Power Functions and SBrick
This is my first proof of concept RC mod of the 42078 Mack Anthem truck with Power Functions Servo motor and L motor, controlled via SBrick. I’ve also posted some updates and correction of my review published yesterday. I was informed via the comments how to properly operate the crane so I did a test again and apparently the whole structure is much more stable when the trailer is connected to the truck. As you can see I’m not an experienced crane operator or truck driver but I’m learning quickly 🙂
I’d like to share a small but agile creation – the remote control mod of the 42033 + 42034 Extreme Off-Roader combined set. Additional parts (mostly for steering) were used only from the set 42035 Mining truck.
The sets and Power Functions components are:

- 42034 Quad bike – http://ebay.to/2fiyVqo — http://amzn.to/2zki9Qh
- 42035 Mining Truck – http://ebay.to/2xxHpo7 — http://amzn.to/2yb01Hv
- PF L motor (drive) – http://ebay.to/2wF3Kgc — http://amzn.to/2zlJtxD
- PF Servo motor (steering) – http://ebay.to/2x89pP0 — http://amzn.to/2ApqzGf
- PF Lights – http://ebay.to/2x8jueR — http://amzn.to/2zmfHZK
There are multiple options for the remote control:
- PF Rechargeable Battery box (8878) – http://ebay.to/2xkDw53 — http://amzn.to/2zBunqJ
or AAA Battery box (88000) – http://ebay.to/2xjTbBV — http://amzn.to/2zmZAuS
- PF IR reciever (8884) – http://ebay.to/2y5KkRV — http://amzn.to/2y7WDgd
or Sbrick – http://ebay.to/2eDtXUu — http://amzn.to/2AnwHyN
- Buwizz – http://buwizz.com
For the video I used the 8878+SBrick combination as the control was easier with an USB gamepad through the SBrickcontroller app. It turned out to be a very fun little car, pretty quick considering the size. Enjoy the video!

After building the 42069 Extreme Adventure set the next challenge was to motorize it. Luckily the set has a spacious internal structure, it is pretty easy to squeeze in several Power Functions components. The aim was to add the Power Functions parts without taking apart the set completely or to change the original structure, so obviously there are more elegant ways to hide all the motors and to upgrade the suspension and the drive train. The list of the added elements:
