I'm going to create a drone (Quadcopter). It is going to be 40cm x 40cm. The propellers will be 25cm each. What motors should I use? As cheap as possible but still powerfull enough to make it fly easy.

Should begin from the beginning. The designer needs to start with basic information - size and total weight of vehicle.... and total amount of weight to be carried, configuration - eg quad-copter/hex-copter, aeroplane type etc. And then you need to build up knowledge on motors for UAV, such as for heavy lifting UAV or light-load UAV.
Plus need to read up on aviation rules. Eg....where are UAV allowed to fly legally.

Unlikely.
Step one, read this
Step two, abandon those plans for now.
Stick to simpler projects until you figure out what's what and stop licking 9v batteries.
stop licking 9v batteries.
How else would you know if they are good?
Hmm well looks like everyone thinks you need to be a genious and have few years experience to create a drone. I can guarantee I'm not going to have any problem when it comes to programming it (Few years experience). The only problem I have is on the electric side. I already have few motors in mind but I asked for a oppinion but it looks liike noone is talking on topic.
I mean, people MAY have gotten the wrong impression of your understanding of things when you wanted to browse webpages on an Arduino and couldn't tell the difference between a motor and a motor controller. It's entirely possible you were just joking.
I decided to make the drone 40cm * 40cm and have 25cm propelles.
I'm thinking to use this motor : A2212 1000kv Brushless Outrunner Drone Motor for Aircraft Helicopter Quadcopter for sale online | eBay
Now i need a speed controller and most of them are really expensive (no idea why...). But i was able to find this one a little cheaper : http://www.ebay.com/itm/10A-Electronic-Speed-Controller-RC-ESC-BEC-For-RC-Helicopter-Brushless-Motor-/401161863325?hash=item5d671c409d:g:adcAAOSwdzVXotIy
Is it good?
Reading all the comments still couldn't understand what kind of "Drone" you want to build?
Airplane?
Helicopter?
Quadcopter? Hexa..etc?
Mono prop. ?
drone 40cm * 40cm and have 25cm propelles
Quadcopter?

Quadcopter.
Ok finally we know what you want to build.
Quadcopter, you need to have 4 motors, 4 props, 4 ESC, a X body or square, you chose that, battery,
that's the basic you need, you will need as well a balancing / control circuit and a radio module.
That's all the components you need to build a simple quadcopter.
1.Next we need to talk about the weight, you want to add extra stuff on it or just the components?
2.How big you want it to be? (ofc you gave the dimensions).
3.What material you plan to build the frame?
4.What flying time would you like?
5.What Radio Range? meters/km?
- You plan to buy a radio and balancing circuit or to build on your own? there is options we can chose.

- Just the components at first but I'm going to play with it later and add someone other stuff. So I need a motor powerfull enough to support the main drone + 100-200 g extra
- Aluminium.
- At least 10 minutes
- ~100 meters.
- I never tought about a balancing circuit. I'm going to create it myself if it is needed.
By radio you mean something to receive commands? If so, I'm going to create it too.
Btw. This pack might be perfect for what I need : http://www.ebay.com/itm/High-Quality-4X-1806-2400KV-Brushless-Motor-4X-Simonk-12A-ESC-for-DJI-H250-/291561834897?hash=item43e2708991:g:c6wAAOSw-W5Ut001
What do you think?
EXAMPLE:
So 1st of all you need to chose the right motors/props, for example we got 1000kv motors with 10inch
prop with give max thrust of 400gr,
400gr * 4motors = 1.6kg (1600gr)
Now we got 1600gr all 4 motors at 100% thrust, we need to lift up the quadcopter at 40~50% throttle,
which means your quadcopter should be maximum weight 800gr recomended, WHY? If you add to
quadcopter 1600 gr in total the quadcopter will not be able to lift at all and will burn your motors/esc and heat
up the battery a lot.
You need to put maximum weight lower than half of your motors can lift.
BATTERY:
You have 4 motors/ESC for example 10A each ESC and your motors works with 3 cell battery with is 11.1v
If we calculate the maximum throttle of your quad 11.1v * 10A = 111Watts * 4 motors/esc = 444Watts
Your battery let's say 11.1v 2.2A it's almost 25Watts per hour
One important thing, while you picking separated motors and esc remember to buy esc 5A more than recomended, if you throttle at 100% your esc will heat up really fast.
Any question till now? This topic will be really big

Got it. Let's talk about the motor + speed controller. I got 2 options.

Which one is better?
Personally I wouldn't buy anything without testing it or seller data:
Gladly I wound a video of your motors:
A2212 Motor and 10x4,5 Propeller
Looking the video setup we got same motors with 30A motors
which gives at full thrust 700gr, 50% approx: 400~500gr let's say 450gr, personally i would chose 350gr.
350gr * 4 motors = 1400gr / 2 = 700gr, so with this setup I would recommend a 700gr quadcopter.
Is that ok for you?

Is that ok for you?
Sure. 700gr is perfect. So first option?
Yes you can buy the A2212 motors with 10x4.5inch prop as in the video, i would recommend that
because we got real available data.
BATTERY:
While talking about ESC you need to be sure you buy the right battery, for example
11.1v 2.2A but you need to chose the C Rating as well, what is that?
Example:
If we got the battery I described you get the 2.2A * let's say 10C (by the C rating)
2.2A * 10C = 22A, that's lower than your 30A ESC, so you need to chose more C than your ESC
so the battery could supply the Amperage the ESC needs.
Another battery
11.1.V 2.2A with 30C
2.2A * 30C = 66A, that's better double than 30 ESC, if it's more that's ok but if it's lower that's a problem and your ESC can drain more power from the battery and burn the battery so rememer buy
a higher C rating for your battery.
As well be sure your motor recomended LiPo cell voltage.
questions?
next! ?...
So this one should be ok? http://www.ebay.com/itm/Hot-Power-11-1v-2200mah-Li-Po-Li-Polymer-Rechargeable-Battery-AB-/252372976831?hash=item3ac29a04bf:g:UNUAAOSwYmZXJFYW
The seller say it's 20C but i can't see anything on the battery.
I wouldn't recommend it, try to find other one.
