[:-]I am baffled by this too I have a corona with an atomic force motor and a phoenix 35 ecs so what voltage do I need? What about the amperage? Most of the websites with litho for sale don’t mention amps just volts so does that mean I shouldn’t worry about it? I want something with good power and long flight time (yea I know I want it all) I really want to use lithium because eventually I will be switching to a brush less set up so I want to purchase only one charger and get longer flight time with my brushed motor any one got any advice for me?[&:]
