RE: battery advice
More than likely true if your very first flight will be with a Cub. I really enjoy mine but they are not beginner planes by any stretch of the imagination. The ground handling is tricky (especially on takeoff), they are corks in the wind, they are easy to stall if your throws are too hot, and they have very little self-righting characteristics. Are you going to be working with an instructor? If not, you can go ahead and back over it with your car to save yourself some time. Whatever you decide though, best of luck to you and I hope you have a great time.
