Here at The Lego Car Blog we’re big fans of up-cycling. Repurposing one thing into another thing is both advantageous to the wallet, and means that one fewer new thing has had to be made, usually by digging something out of the ground/cutting down a tree, melting/refining it in a factory, and shipping it in a giant box full of other new things half-way round the world.
Of course LEGO by design is an up-cycler’s dream. Endlessly reusable, reconfigurable, and hand-down-able, it is the antidote to crappy single-use plastic toys that will last a thousand times longer in landfill or our oceans than they will in the hands of a child.
Cue previous bloggee M_Longer, who today demonstrates LEGO’s greatest attribute brilliantly by up-cycling two 2025 entry-level Technic sets into entirely new models.
M_Longer’s JCB Fastrac (above) uses every one of the parts from the 42199 Monster Jam DIGatron set, whilst his helicopter (below) swaps the ocean depths of the 42201 Deep-Sea Research Submarine for the skies, and includes a pitching main rotor and a hand crank that turns it and the tail rotor simultaneously.
There’s more to see of M_Longer’s 42199 JCB Fastrac, or alternatively his 42201 helicopter, at both Eurobricks (where links to building instructions can also be found) and Bricksafe, and you can take a look at each up-cycled alternate via the links below;
