This means you need your own radio control system. A transmitter and a receiver.
The last line specifies the battery pack to power the motor. Hobby King can sell you the right one.
That airplane is a bad choice for a first-time flier. It is low wing and will be hard to control. It will do advanced acrobatics when flown by someone sklled, but a beginner will just crash it.
Start with one of their trainers. Then move up later. If you think you will save money by buying only the plane that you will fly when you are a sklled flyer, you'll lose more money in crashes than it would have taken to buy one trainer and one more advanced plane later.
Buy a four channel (or more) radio. You can use the same radio in your second plane without buying it again.
If you want this plane, find a trainer that uses the same battery to power it so that you don't have to buy a new battery.
