Review of the 8865 C Model. https://paulbtechnic.blogspot.com/2025/12/lego-technic-42213-c-model-8865.html

No, it was the whole Technic forum had a theme applied, I could not see any text, even my own posts from the past.

Yes, same here. Looks like a theme has been. Applied that has not worked...

Build an A model under 250 / 300g and then build a B model, using the same parts.

That is great news :)

Late to the party, but finally got this set :) https://paulbtechnic.blogspot.com/2025/11/review-lego-technic-mercedes-benz-g-500.html

This build started life as the LEGO Technic 42121 B-Model, but it has been heavily modified and redesigned into an articulated tractor, something that is compact, functional, and full of character. Features HOG (Hand of God) Steering: Smooth and precise control from the top of the cab, making it easy to maneuver the tractor through tight spaces. Opening Engine Cover: The hood flips open to reveal a working engine connected to the front axle, showing off the mechanical detail inside. Rear Mounted Lift Point: Designed for versatility, this rear hitch system allows for a range of attachments. I’ll be designing and building several different tools and implements to connect here soon. Design Notes Transforming the original 42121 B-model into this tractor was an enjoyable and creative process. The articulation joint adds a lot of realism and play value, and the proportions feel just right for a mid-sized off-road tractor. The color scheme, mostly yellow with black accents and a few pops of red and grey, gives it a rugged industrial look. I’m really happy with how this one turned out — a compact, functional Technic build with plenty of room for customization and future add-ons. Stay tuned for the next post where I’ll start developing some of those rear attachments. http://paulbtechnic.blogspot.com/2025/11/lego-technic-articulated-tractor.html

This is great, I might get another copy of 42213, just to build this :)

A video of some changes I have made to improve this. https://paulbtechnic.blogspot.com/2025/11/lego-technic-42198-c-model-combine.html

Review: LEGO Technic 42198 C Model - Combine Harvester On the website Rebrickable, the model is listed as MOC-226110 and titled “42198 Combine Harvester” by artemisovsky. It uses 277 parts. It’s an alternate build of the official set 42198‑1 Bush Plane (which has 333 parts) — meaning you can take the parts from that Bush Plane set, use no extra spares, and build this combine harvester instead. The key features listed: - Hand-of-God (HoG) steering on the rear wheels. - A working thresher driven by the front axle. - An opening hopper. - A functioning header (the front cutting bar) with raising and lowering. - A movable auger. The designer notes that the build uses some “unusual” wheel gearing because the original set only provides three wheels and he had to press a tire with a gear — which might be a “grey area” in terms of part legality. After building this, it seems to work "ok" but does have some room for improvement. Why this is interesting This MOC has several appealing angles: Compact alternate build: Taking one set and converting to something entirely different is a great fit for my mindset of doing more with less. Mechanics rich build: Steering, driven thresher, header lift/lower, auger movement — plenty of mechanical motion to explore or modify. Strong modification potential: While this is already a well-designed MOC, you could use it as a basis for further customisation. Minimal parts overhead: Because it uses only one official set, it’s efficient. I value efficiency and predictability in my builds and this ticks that box. Final thoughts This combine harvester MOC is an elegant example of how you can extract more from a single set, something I value given my low-footprint/efficient hobby orientation . It also aligns with my love of mechanical motion and system design. Building it gives you a fun, relatively compact project, and turning it into a modified version adds even more play value.

I personally am focusing more on older sets, to do MOD's and MOC's. I only buy new sets to get parts these days.

This is amazing and my next purchase will be these two sets to build it.

Working brakes would be awesome.
