So now you have to buy 3 sets of competition batteries and 3 sets of practice batteries. How does that save someone money?
I'm buying 4 sets of batteries for my plane. If my plane needed an expensive, light set of batteries to make weight, then I could buy 3 sets of heavy, cheap batteries and one set of expensive light batteries. Given the situation, this seems like a cost effective approach.
You need at least 2 sets of batteries to compete with. Sometimes you have less than an hour between flights and what happens if you pack goes bad.
