I have a phantom 1 and I love it. Have not had any issues. I talked my brother into buying one and he is having trouble getting it in the air for the first time. When he turns his transmitter on, the red light on the transmitter comes on for a second then flashes 5 times then stays on solid. He has also been unable to calibrate his compass. He tries to toggle the GPS/Atti switch in the transmitter but the Phantom light stays at a yellow flashing, it never gets to the solid yellow needed to start compass calibration. As just mentioned, the Phantom light stays at flashing yellow. I think his transmitter may be bad. Any thoughts?
