You know - I'm right now looking at purchasing a 600 and I got all the stuff I want picked out - now I'm getting into finding out that the "Charger to end all chargers" that my LHS guy sold to me a few months ago only handles up to 3 cells. Now I've got to get a whole new charger, not only that but I've got to get an adapter for whatever brand battery's balance lead charger to make it compatible - because I'm reading a lot about how you really should balance charge a 6s. Pain in the ass - I'm also reading that the Align battery is crap - they tested it out and found that it was way over temp after only a mild 3D run of about 5 minutes. I'm thinking thunder power 5000Mah - but you know the costs of this crap tags on an Extra $89 for the better battery, and a whole new charger that I priced at around $120. I was already looking at $1400! Now I gotta spend more? I was thinkin about sayin to hell with it! Who wants to wait for a battery to charge anymore? I know I'm getting sick of it - fly 8 minutes - wait for an hour - fly 8 minutes - oops - last battery isn't cooled down yet - wait another 20 mins - ok now charge and wait another hour - I'm thinkin about junking the whole 600 idea and going straight to a Nitro - I'm almost positive I can get a nice Nitro setup with everything I need to fuel it up and start it for under $1500 - AM I RIGHT? Hell - I can fly it for 20 minutes - fuel it up for 1 minutes - and fly it for 20 minutes again - Much more flight time I would immagine.
