airwolf 450 calibration help

[Gigg]

I was not able to get my helicopter to get the gps satellites the light was blinking yellow and would not turn to green. I am thinking it needs to be calibrated? It came ready to fly and i only had to attach the blades. I dont see any way to get to the usb port! im guessing the body has to be removed. Im not sure how to do that! could someone give me some guidance or a link to a video that might help?

Thanks for any assistance
