Good for all gamers, let's talk about the new defensive building and its use, el controlador aéreo.
The air traffic controller has been created to cause difficulties for air strikes, because in war there are many who use dragons to get at least one or 3 stars.
Air Traffic Control is nothing but a device launches powerful wind gusts on air enemies, regardless of the enemy to be.
For now we only have 1 controlador aéreo, it may eventually introduce some more as more and more people need to put an expert attacking and difficulties.
We can turn around 360 degrees at several positions, and convenient place some focused and pointing to an area where we have defense rockets.
We have 6 levels of air traffic controllers to improve, and these improvements are reflected in the power of the blast of air and in the distance , can reach up to 15 casillas.
Once activated the air traffic controller, it can automatically rotate to various sides to hinder air enemy advance.
We can unlock the air traffic controller from the level of council 6 and it occupies a size 2×2 in the village , still a very small space.
Then let's talk about each of the levels and their differences :

El controlador aéreo level 1 is an air container located where a spring presses and expels the air inside large force.
The air is expelled through a mouth of expulsion which will increase as the levels increase.
The structure is made of wood.

In level 2 we can see that the mouth of expulsion amending this being a little older and knots of the previous level become elements of silver plate.

In level 3 Air Traffic Control observe how the support legs are reinforced with more elements of silver plate. The upper base is also strengthened with an edge making it more resistant sheet. The air eject port remains the same as in the previous level.

In level 4 we see as the only differences with the previous level are the bases of the support legs have a new molding silver plate fixed to the ground and the upper base plate introducing silver and gold items.

In the air traffic controller level 5 We can see several changes. The wooden legs are reinforced with golden ornaments and anchored to the ground with more force through a new anchors.
In the upper base we see the predominance of golden color, making more robust the structure against enemy attacks.
The air exhaust mouth has changed color and shape, now is grayish blue against previous levels and its tip is dark gray, a parte, It is slightly longer.

This is by far the highest level of air traffic controller. As we can see, the air ejection face is maintained as in the previous level. What really changes is the disappearance of almost all the elements of wood and silver, giving way to the golden elements.
Here you have a picture-scheme so you can see the evolution of air traffic controller and what it costs us upload:
| LEVEL | Restoring force | LIFETIME | COST OF GOLD | TIME FOR IMPROVEMENT | EXPERIENCE | LEVEL OF HALL |
|---|---|---|---|---|---|---|
| 1 | 1.6 casillas | 750 | 500.00 | 1 day | 293 | 6 |
| 2 | 2 casillas | 800 | 750.000 | 3 days | 509 | 6 |
| 3 | 2.4 casillas | 850 | 1.250.000 | 5 days | 657 | 7 |
| 4 | 2.8 casillas | 900 | 2.400.000 | 7 days | 777 | 8 |
| 5 | 3.2 casillas | 950 | 4.800.000 | 8 days | 831 | 9 |
| 6 | 3.6 casillas | 1000 | 7.200.000 | 9 days | 881 | 10 |
As we can see, the more we climbed the highest levels of air traffic controller recoil force will act on the air enemy, You can hold a little further from our air defenses before they are destroyed.
The strategy for placement would be put near other defenses and our bursts of air defense our rockets to be destroyed not easily give us support and destroying enemy air.
If we want to destroy, we must attack them directly with a montapuercos and a giants to eliminate them as soon as possible. The giants entertain the enemy defenses and montapuercos do the rest of work.
The cost to improve the air traffic controller is not very high considering what cost us improve other defenses, while improving the level 5 to the 6 It is a bit excessive.
Air Traffic Control is a very good air defense, but has not defended against enemies terrestrial, so I recommend that mejoréis before a defense that defends both by land and by air as may be the infernal towers, teslas or archers towers the towers wizards.
