I'm new to the hobby. I bought a X5SW and love it. When it worked. My problem started by charging it one day and now the quad it's self won't turn on. No lights and it won't sync with the controller. I've only had it a week. Could the battery be bad? It powers the camera because the red glow comes on it. Tried disconnecting the camera. No help. What exactly does a bad battery do? Thanks..
An inexpensive (~$10) multimeter is something all flyers should have. That way you can check the battery right off the charger, it should be about ~4.2V. Did you crash it?
