Perfect technique and a lot of content:

The crawler excavator 8043 Kit consists of many parts.
The construction is very complex. Alone the gearbox is amazing.

The engines are equipped with very many shafts and gears with
the control elements connected. A small marvel of technology. After the building, took me in 1-1.5 days,
(2x parts (shafts) I stupidly mistaken)
has the same model works beautifully from the outset,
although I as due to the complexity and the fear,
to have something not installed correctly, had my doubts.

The model runs flawless. Because of 4x small engines
but not as fast as models with large engine,
the yes has more power.

In the model a lot of infected technique and you learn a lot about
clever Lego Lego mechanics and technique, what you can safely use in other models.

The Most Important:
The model contains for a cheap price lots of important
Special components such as the motors 4x, 4x actuators (actuating cylinder), a large number of gears and special pieces,
and not forgetting 2 IR receiver, IR transmitter and 2x a Bateriebox.

The parts alone are a treasure trove of their own ideas un conversions. Those who wish can separate IR receiver and 2x additional motors convert the excavator so also with 1x, 6x that all functions work simultaneously. (Assuming some skill).

In the life I've deducted a point.
The model is, as with Lego usual, though quite stable.
Due to the shape of the long boom and the complex
Construction, but it can eventually lead to damage of parts in case of accidents.

Conclusion:
The model has a lot of technology for the money.
Is not just for kids. ;)

PS Be sure to download the manual for the second model in Lego.

Greetings and happy building.
