My balance charger (from Flight Power) was charging for the first time, when a bluish white smoke came out the sides. At the hobby store where i purchased the charger they toke it apart and found out someting inside it was loose (and causing it to short circuit). So i had it replaced. Also had to go through 3 of Flight Powers batteries because all of them had some sort of deffect. I'm starting to lose trust with Flight Power's products.
