I agree with Ybenjulkay2x. Even though they are free, with this type of helicopter you will learn some really bad habits as they will not fly like a higher end heli. I found this out the hard way. These small fixed pitch helicopters are very hard to learn on. They are unstable, almost impossible to trim and forget it on a windy day. I finally broke down and got a 600 size electric and after I finally got the nerve to put it into forward flight I was amazed how stable and easy to fly it was. My experience with the larger heli is nothing short of wonderful. So take it from a beginner helicopter pilot, If you want to actually learn to fly helis, don't waste your time with toys.
