Hi, so I got my hands on an old P1, that has no remote for it, and I can have it if I can get it flying. I bought a new DJI remote for it, freq 2.4 ghz. The UAV boots, flashes 4 times green and then on to flashing yellow all the time. I've tried manually linking the UAV to the remote, by holding in the button in the battery bay of the UAV. The LED in the battery bay of the UAV is flashing red. When I hold it in it changes to flashing green. I hold down throttle and turn on the remote, and no success.. The LED On the remote remains red and the LED on the UAV is still flashing Never is the LED in the bay constantly red. Or off. Any ideas?
