An exceptional model in every respect!

The LEGO feat of this model is to offer a fully remote controllable device (infrared) with 6 + 1 movements controlled by only 4 engines. The dual control allows the three movements at a time.

Motorized functions are:
1. Left Chenille
2. Chenille right (operated in reverse, the loader pivots)
3. Rotation of the entire assembly placed on caterpillars
4. Vertical arm
5. Horizontal arm
6. Bucket
7. motorized Lever switch to change function (1 motor to switch the functions of the three other engines)
Moreover end stop of a movement, the motor "hold" (blocks) without any cracking nuts, so super nice (not like on other models like the 8265 bulldo)

I encourage you to go see the setechnic website that details what model.
Well thought out and well done, the mechanical system is bluffing efficiency and complexity
I bought it for myself, but my child 9/10 years helped me build it, he realized the whole arm, with a small error that blocked the gimbals certainly, but it was regaled by assembling the fairing (and since he is finished, he squatted on the remote). Even Madame was packed for playability.

> Gameplay: 5/5
> Realism: 5/5
> Design: 4/5
> Inventory: 5/5
> Mechanical: 5/5
> Difficulty in building: 4.5 / 5 (well thought out, easy enough to climb but requires care)
> Clarity record: 4.5 / 5
> Batteries: 3/5 (it takes not less than 6 + 6 LR6 AAA rechargeable as in my case)

Model B. 4/5 (yes there is a second model! Loader bulldozer)
> Surprising Reactivity caterpillars
> Designing a bit less extensive but still 4 motorized movements!

I am not a collector but I appreciate the sophisticated models.
In my opinion this is a great set for those who design their own models. The inventory also helps build other Lego Technic models by adding some other "rare" coins.

>>> For me it's the best of all time box designed by Lego.

Note on the price:
- The Amazon store is always well placed prices on the big boxes. Note that prices fluctuate.
- Bought at 147, I consider it excellent value for money!

Only unfortunate side item LEGO: he did not book the second manual models for a few years (to download on their website)
