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.

I love the level of detail you have managed to get in to this, well done.

Very nicely done.

Amazing....

Project 42213 Unimog Mods and Attachments – 11/09/2025 – Rear Mower Video - https://paulbtechnic.blogspot.com/2025/09/project-42213-unimog-mods-and_11.html

Project 42213 Unimog Mod - 08092025 - Tilting Tray Removal and Rear PTO Added Today’s update on the 42213 Unimog C Model brings a big functional change at the back of the truck. I decided to remove the rear tilting tray feature. While it added some realism, the movement was limited and it restricted what I could attach to the truck. By taking it out, the rear of the chassis is now cleaner and provides a stronger mounting point for future attachments. In its place, I’ve added a rear PTO (Power Take-Off). This modification allows the Unimog to power rear-mounted equipment through a simple gear connection. The PTO is driven via the central driveline and sits neatly at the back of the chassis, ready to connect to different add-ons. This upgrade opens up a range of new possibilities for attachments — such as mowers, winches, augers, or anything else that can be powered by the truck’s gearing system. The PTO is geared with a small bevel gear assembly (shown in the picture above) and keeps the build compact while remaining robust enough for Technic-scale accessories. With the tilting tray gone and the PTO installed, the rear end of the Unimog is now much more versatile and better aligned with the “multi-function truck” idea I’ve been working towards. Stay tuned for the first attachment to use this new PTO system! Video - https://paulbtechnic.blogspot.com/2025/09/project-42213-unimog-mod-08092025.html

I purchased 8832 when it first came out (1988) and have purchased three more copies off eBay in the last 15 years, these have all had the same instructions. Given that 8720 came out in 1990, and this was a number of years after these sets were released, I am not sure if / why TLG would have gone back and made official instructions for these older sets, especially the smaller ones, such as 8832 and 8835.

If they can make the "new" 42122 as good as 42213, I will be very happy.

That is coming along really well.

I really love the level of detail in this.
