Hello veteran aviators.I'm new to the sky, but I have owned many rc cars, from childhood to adulthood.... Now I'm going to take to the sky and I hope I'm welcome to share the air space with everyone. After a lot of research and a shallow wallet a X5sc black in color, is what I decided to purchase. I'm already looking to upgrade the battery and add a router antenna as soon as possible! Any ideas for the batteries that work best in the X5?
