Good point Dsegal and I totally agree but I'm thinking of keeping the least amount of weight in my airplane, actually regulators have charging switches included like a regular switch, I only have 3 planes so if all my planes have 1 lipo 2 cell 1000 mah each i would only need 1 charger, also I beleive lipo batteries last alot longer than nimh and nicd. I could be mistaken and that is why i'm asking questions and figure out what i'm going to do depending on cost and whats the best possible route to go. so I'm doing some research.
