Review: Fully Lego compatible - Just finished this build today. I made e modifications that I think turn this into an excellent RC excavator. First I swapped out the dual battery boxes for a single 6 channel battery and remote with proportional controls. Mould King sells it for $40 her on desertcart. It's a tight fit. But will fit into the rear battery box spot unmodified. Just adjust the position of the technic beam on top of the xl motor forward one stud. 2. The mounting brack that attached the rear of the lift cylinder that controls the sticks in and out movement. ( Located on top of the boom) Needed to be raised up by one stud, ( or hole) to make the mechanisn work smoothly and not bond up. 3. The bucket it comes with is way too wide for a real excavator. So I 3d printed my own bucket that looks much more realistic. Basically the same exact shap but half the width. Every piece was there and it's a fun build. Definitely challenging. Pay close attention to details and go slow. Keep an eye on some pieces that look almost identical to each other but have slots in them to mate up to other parts. If you use the wrong ones, you'll regret it later, and be tearing pieces apart to swap them. Trust me! All in all great build. Just needed a few tweaks to make it perfect. Fully 100% compatible with Lego and Lego technic. Even the motors are Lego power functions basically.
Review: Totally worth it if you dont need Lego-level quality - If you just want to build a unique and well engineered mechanical model for the joy of doing it, then this is GREAT value. If all of your problems are first-world, you have $500 to burn, AND you demand the absolute finest quality control in every respect, then buy yourself some lego and what are you doing even looking at this? Anyway, I was consistently impressed with the fit, design, and features throughout. The instructions are FINE. There was no point where the quality of instructions was nearly as low as the price. I expected absolute trash based on the price! But this set was clearly produced with much more care than chinas typical level of effort when producing knock-off type products. The parts fit together in a consistent and surprisingly precise way( not as good as lego but way better than COBI). They consistently exceeded my (minimal) expectations with sufficiently detailed instructions, and mechanisms which were engineered with a clear priority for high functionality and aesthetic over cheap simplicity.

### ⭐⭐⭐⭐⭐ Buy with coinfidence
*by B***R on December 21, 2022*

I bought both this 13112 RC Excavator and the RC Tractor Building Kit from this seller and they were both great products. Half the fun with these kits is the point of building the models yourself, and when you can drive them afterwards, that's just the extra bonus. Neither set had any problems, just make sure you get the stickers on the right area on your first try. Only 1 small piece from the excavator was missing but when I informed the seller of it, they shipped over a replacement right away. Now that's true customer service, my set is 100% perfect and I'm 1 happy customer.
