They are not really hard to fly. Just takes some practice to get the hang of it. Need to get used to the stick controls and whats does what while flying. Those on that website do fly fairly easy for the money. One thing though to keep in mind is that once you learn you will be addicted! Then after that you will want something better.
If I was you and wanted to get into flying I would go with a regular trainer. This way you will have everything you need. After you learn to fly the plane well you can always use the same gear for another plane later. Now with that plane on that website you are in a way limited.
check out this link. This is a good way to go.
