I have A, B and C power packs. I've hunted around for recommended batteries but had no luck. The pack pages at the store site don't contain that information but I feel I've seen it somewhere. Am I missing something? I have no idea what I need. Planes are built or almost built. Receivers are arriving. I have a bunch of batteries a buddy left me. A newbie learning on the fly on my own for the most part. My buddy got me hooked and then moved to Cleveland chasing a woman. So he's lost in action, at the moment.
