batfish, your right about the fast charge option with the fma packs and you dont have to worry about checking for yourself, if they are balanced. that is a factor i did not weigh in when comparing products. if i were a competitive racer, i would surely end up going with the fma packs, mainly because you can charge them so quickly. im just a daily basher and i have nothing but time on my hands, it can get really boring in afghanistan when there are no broken helicopters.:C:
