Hi , first I would like to apologize for the newb questions . I am recently getting into the field and need lots of help and guidance. Well anywho I have a flying 3dx8 GPS worked at first but now I am not getting any GPS at all . And when I calibrate it now by flipping switch up and down the light initiates and rapidly blinks green , but nothing else happens when I go through the process it just keeps blanking green. I tried connecting to computer but not sure if I need a program or something .. please help and again Im sorry for newb question
