What charger are you using? For a cheap one, get this one, but only if you are planning on using 2s or 3s lipos. Also get some of these so you can actually measure voltage, and also know the voltage while flying. For servos, understand that these are the things that actually allow you to control the plane in the air, so you don't want to cheap out too hard on them. These are the ones I use. Also, what radio are you using? If it is not this one, dont buy it.
