Yesterday I tried to fly a P1. Did the spin-moves to calibrate the bird and powered it up. The lights would be blinking green as if they had good satellite signal so I would take off and I'd hover in the air for a few minutes and all is good. I would then go forward with the bird and in about 30 feet (sometimes more sometimes less), the back light would start blinking red and the bird would immediately land. I made sure the battery is charged and even checked after it landed and it was still charged. The P1 was bought off ebay to help practice and let my brothers learn, but I'm not sure what is going on here since my P2V+ flies great around here. I made sure all the firmware was up to date. Any thoughts?
