Très belle pelle mécanique
Aucune pièce manquante. Le contrôleur manuel fonctionne conformément. Bien que le plan aurait pu être plus clair, il est simple. Avec de la patience et de l'effort, le résultat final est impressionnant. Je suis très satisfait de la qualité ! Le rapport qualité prix est excellent. Je recommande vivement ce produit.

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 Amazon. 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.

What an awesome project!
If you want to exercise your mechanical abilities this project is for you, never thought I’d be taking over a kids toy but it proved to be too much and grandpa had to take over, great on keeping the mind active!!

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.

Awesome! Mostly
This is a great build! Drives great, operates great! Only downsides: 1) you have to turn the remote off/on if you want to switch from driving to using the bucket. 2) the drive control is reversed on each side so to go forward one side is the top button the other is the bottom button. Tried to fix that but failed. 3) the bucket is WAY, WAY to big. You can't pick up anything because the weight is too much for the gears. I tried picking up a half bucket of dog food (it was there. Lol) and the gears just clicked or stopped all together. I have also never seen an excavator with a bucket that size (proportion wise) in my life. it looks like they used the bucket from a loader for this model because they didn't feel like making one specifically for the excavators. If they put the right size bucket with this it would be PERFECT. Maybe I'll make one out of ABS sheet for it. Lol
