MOC - LEGO Technic 42198 C Model - Safari Helicopter

When it comes to LEGO Technic, I love the challenge of creating alternative builds (C Models) that push the boundaries of what a set can do. My latest creation, the Safari Helicopter, is built entirely from the pieces of LEGO Technic 42198 - Bush Plane, making it a true C Model that doesn’t require any extra parts.

Design & Features
Rotors & Engine Integration
One of the standout features of this build is the functional connection between the main rotor blades and the flat-four engine. As the rotors spin, the pistons move, adding an extra layer of mechanical realism to the model. This was a key element I wanted to include, as it brings the technical charm that Technic fans appreciate.

Working Landing Gear
A helicopter isn’t complete without functional landing gear. In this design, both the front and rear landing gear lift and lower simultaneously, providing a smooth and realistic mechanism. The synchronization took some fine-tuning, but I’m really pleased with how well it works.

Sticker Integration & Aesthetic Challenges
One of the unique challenges of creating a C Model is working with the pre-applied stickers from the A Model. Rather than seeing this as a limitation, I embraced it, carefully designing the bodywork to complement the original sticker placement. This meant rethinking panel positioning multiple times, allowing the model to evolve organically as I built it.

Color Scheme & Final Thoughts
At first, I wasn’t sure how the black, white, and yellow colour scheme from the Bush Plane would translate to a helicopter, but I think it works surprisingly well. The zebra-like patterns and the “Wildlife Service” branding give it a distinct, safari-ready look, making it stand out from traditional helicopter builds.

I’m incredibly happy with how this turned out. It’s a unique take on a Technic helicopter, packed with functionality and built only from parts included in 42198.

Mini Review - LEGO Technic 42197 - Mini Backhoe Loader

LEGO Technic 42197 - Mini Backhoe Loader: Is This Even Technic?

LEGO Technic Set 42197 - Mini Backhoe Loader really stretches the definition of a Technic set. With only one real function—the bucket raising and lowering—it feels more like an advanced LEGO City build than a proper Technic model.

While the single function works well, the lack of mechanical complexity is disappointing. Manually moving pieces doesn’t count as a function, and without many gears, pneumatics, or a proper linkage system, this set lacks the engineering depth expected from Technic.

Overall, it feels like a simplified take on construction equipment, but not something that lives up to the Technic name. If you're after a true Technic experience, this one might not cut it. It was a easy build and for somebody taking the first steps in to the Technic world, it is easy enough to build, but it also does not really "show off" what Technic is all about.

MOC - LEGO Technic 42203 C-Model - Road Grader

LEGO Technic sets are always a source of inspiration for custom builds, and the LEGO Technic 42203 is no exception. While the official A model offers some good functionality, the true beauty of Technic lies in the ability to create alternate builds (C-models) that push the limits of what the available parts can do. One such build is the Road Grader, a construction machine that levels and smooths surfaces.

Concept and Design
The idea behind the Road Grader was to maximize the use of the truck's parts, while introducing a functional blade mechanism, rippers and steering. Road graders are essential in construction and roadwork, making them a perfect subject for a LEGO Technic alternate model. The challenge was ensuring a realistic blade movement while keeping the structure stable and maintaining playability.

Key Features of the Build
- Steering: The grader includes a steering mechanism often seen in real-world graders, providing precise manoeuvrability. This can be controlled via the steering wheel inside the cabin or via the top exhaust funnel.

- Adjustable Grading Blade: The build includes a blade that can be raised and lowered simulate grading functions.

- Rear Ripper Attachment: An added ripper tool at the back can simulate breaking up tough ground before grading.
The design and building process took about 10 hours, across a few days.

Final Thoughts
This C-model of the LEGO Technic 42203 dumping tip truck, takes these parts and makes them into a detailed and functional Road Grader. It captures the essence of real construction equipment while staying true to the Technic philosophy of engineering and creativity. If you own the 42203 set and are looking for a fresh challenge, this build is a fantastic way to expand your LEGO experience.
