Today we are going to look at how I motorized Lego’s 42111 Dom’s Dodge Charger
1. The concept
I wanted to keep this mod as simple and keep the set as original and functional as possible.
I also wanted to use the brand new BuWizz motor as the main drive motor. For steering we used a Power Functions® Servo motor. And of course the modified motor is powered by a BuWizz.
2. Motorization process
The first challenge faced was where to position the drive motor. As stated before, I wanted to keep the same functionality of the V8 engine and the wheelie bar, so the drive motor had to be placed somewhere where it would not interfere. After looking at all the available space and options, I decided to place the drive motor directly behind the V8 fake engine, facing the passenger side. Using a few additional pieces and a 16 tooth gear, the motor was coupled directly to the fake V8 engine.
Next the Servo motor had to installed and connected to the steering system. After fiddling around I found the perfect spot at the rear next to the steering gear. No additional gears were required and the Servo motor fit perfectly in the spot.
After testing the prototype, I noticed that the original gearing had a too low gear ratio, which resulted in a poor acceleration. In order to increase the gear ratio and reduce torque flex on suspension, the rear axle gearing was changed to 1:3.
Last thing left was BuWizz placement. The trunk turned out to be the perfect place and with a single Technic® brick, BuWizz was placed on the bottom. The wires were carefully routed to the trunk and connected to the BuWizz brick.
3. Custom profile
With the release of custom profiles, I turned to our graphical designer to create images for this model’s control profile. He did an amazing job with the photographs which really bring the car and control profile to life.

When can I buy your BuWizz motor?
Soon. Stay tuned.
Any manuals for buwizz motorization of chatger 4211?
And when will be soon?
what is different/better about the BuWizz motor compared to the lego buggy motor?
It’s more powerful and we are working on making it more compatible with the technic system.
Best regards
how much will it cost?
Will the motor be available before Christmas?
hoe duur word de motor?
A Buwizz servo motor would be great too, since Lego stopped producing it.
There should be buwizz physical remotes I would get this if there where
Are there any details about the release of your buggy engine? I’m would love to buy if for myself for Christmas 🙂
Will it be available before Christmas?
Hi
Looking to buy one for a MOC project. Had a look at your app but it looks fairly minimalistic compared to your direct competition at least in terms of design. Any plan on adding the possibility of customizing the inteface (further than just background color)? Possibility to redesign the controls / use custom images?
On the same note, I was trying to have a look at the charger profile to see if customization was possible (even if I have to play with json) but it’s no longer available for DL. Would you mind sharing it again as a reference?
And finally, any plan to add official gamepad support any time soon? (seems to be doable through a 3rd party app currently)
Thanks in advance for your answers,
Regards,

Our App is minimalistic by design. This year we will introduce the new design.
