Well I do have that solar charger, that you seen and liked but I have plenty of batteries for each helis. Each heli has 4 batteries for flights.You need a field charger......you saw mine.....to take with you, so you can stay out there longer.
Yeah, I forgot about that. Pretty cool set up, actually. Next time we fly at the place we went to though, I`m bringing a couple of 10X10 popup tents. LOL.
