MOC - LEGO Technic 42198 C Model - Safari Helicopter

Paul B Technic · March 30

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.

Colour 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.
