While I have no experience with the Flyzone Piper Cub, I would bet that it is a great starter plane.

I do own the SuperCub LP that Minnflyer had a link to. This is still one of my favorite airplanes to fly, and I have several! I can't remember the last time I went to the field and didn't bring the Super Cub along. I find that the Super Cub is good for relaxing flying at around 1/3 throttle, and it is a lot of fun at full throttle.

Last year, I had my 8 year old son flying the Super Cub some as well- it flies very nice.
