An FPV racing quad can cost anywhere between $200 and $900, depending on a variety of factors. This does not include the cost of FPV goggles, which will set you back another $300 to $400 or so.
Keep in mind that you will need to replace parts, especially props, on a regular basis.

An FPV racing quadcopter is made up of the following parts:
•    Frame
•    4 motors
•    4 ESCs
•    4 props
•    Flight controller
•    Lithium-polymer (LiPo) battery
•    Video transmitter (vTx) and receiver (vRx)
•    Antennas
•    Battery straps
•    FPV goggles or monitor
•    HD camera for recording
You'll want to buy a lot of spare props. It also doesn't hurt to have spare batteries, motors and ESCs if you want to avoid waiting around for replacement parts after a crash.
To build and maintain a quadcopter you'll also need some tools, such as:
•    LiPo charger
•    Soldering iron
The parts you choose will depend mostly on your budget. To see what parts we recommend, check out the products section in the website.
 

You have two options:
1) Buy a ready-to-fly (RTF) or almost-ready-to-fly (ARF) quadcopter.
2)Buy parts such as a frame, motors, props etc. and build it yourself.
We can't really say which of these options is better for you. If you like building things, the second option is great. For many of us, building the quad is half the fun. The other main advantage of building your own quad is that you'll have the knowledge and skills to fix it when you crash.
But if you really can't wait to get in the air, there are now some decent RTF racing quads on our store. You might pay a little more than if you had built it yourself, but at least you'll know it flies.

If you're new to flying quadcopters, the first thing you should do is buy a quadcopter, maybe you can refer the link below:

Yes, we know... it looks like a toy, right? Don't be fooled by the appearance or low price. The DLFPV 265mm is an amazing quadcopter that will allow you to practice a range of flight manoeuvres before you move onto a complicated quad. This is very important for a number of reasons:
1   Flying a quadcopter isn't as easy as great pilots like Charpu and Metalldanny make it look.
2   You will crash a lot whilst you are learning to fly.
3   Crashing a large-size quadcopter can be dangerous and expensive.
You will have fun and learn how to fly in a safe and inexpensive way. Most of us started with a quad like the DLFPV 265mm, and they all enjoy it.
 

Quadcopters are very useful and have many different types, for instance quadcopters can be made for filming and lifting cameras or built for doing mid air acrobatics. Well a racing quadcopter is a quadcopter meant to go fast. Extremely fast. Racing quadcopters can also be entered in competitions where they are put into different classes, the most popular is the 250 size.

A quadcopter is multi-rotor copter with four arms, each of which have a motor and a propeller at their ends. Quadcopters are similar to helicopters in some ways, though their lift and thrust comes from four propellers, rather than just one. Control of vehicle motion is achieved by altering the pitch and/or rotation rate of one or more rotor discs, thereby changing its torque load and thrust/lift characteristics.
