Recently, I assembled a 1/10 scale turbofan engine model (Teching DM135). I just finished it and took some photos, which are at the end of this post. I'd like to share it here and see if anyone else is also interested in this kind of mechanical structure.
The engine is based on the F135 turbofan used in the F-35 fighter jet, although the model itself doesn't specifically label that. The whole kit includes more than 600 parts, mostly made of metal. From the front fan blades to the high- and low-pressure turbines in the back, every section can rotate. After assembly, you can manually turn the shaft, and the entire airflow path drives the blades to move. Seeing the mechanical linkage for the first time felt really satisfying.
The manual was much clearer than I expected, and the packaging was quite well-organized. But the screws are really tiny, so I strongly recommend using a magnetic screwdriver to avoid losing parts. During assembly, there are some things to keep in mind: the small parts are especially tiny, so having a magnetic screwdriver and a storage box is a must; each component needs to be precisely aligned—if not, the rotation can get stuck. I suggest turning each section manually after assembling it to check if it moves smoothly. Also, the manual is detailed, but you shouldn't skip any steps or miss small parts. When tightening screws, be careful not to use too much force, as metal parts can be damaged.
The Teching DM135 model is very well-designed. The parts are finely made, with a solid metal texture and high detail accuracy. What I find most interesting is the realistic mechanical linkage. The airflow structure is mimicked through rotating components, and watching it move is quite satisfying. The manual was better than I expected, with clear illustrations that made it easy to follow, almost like assembling the real thing. It wasn't easy, though—it took me about 10 hours to finish—but the final mechanical effect made it totally worth it.
Once powered on, the engine can actually run, and it even has lighting effects, which I've never seen in other model kits. I especially love the semi-cutaway design, which lets me see the internal movement clearly. Overall, I think it's a fantastic experience.

I've been away from the forum for a bit, but recently got back into building and wanted to share my latest project.
Actually, this model is fully functional, and the lighting effects look really cool. If you're interested, I can find some time to shoot a video of it.
A cool, oops I mean HOT, looking model and it's neat that it operates and has lighting effects!

Actually, you know how it is—pictures just don't do it justice
Sure, a video would be helpful to show what this model is capable of.

I've uploaded some updated videos to better showcase the full appearance of the model and highlight its lighting effects.
Impressive. How does it create the vapor effect of the exhaust?
You can add water through this hole, and it will generate 'smoke'. In a dark environment, the combination of lighting effects and mist looks especially stunning.

Very Nice

Very impressive kit! I love the light and vapor effects.
