I've not flown my phantom 2 for a while so I may be a bit rusty on the up to date naza led light sequence. Basically took off and everything was fine. Then I noticed when I went in a forward/backward direction the green leds would flash twice rather than the steady once, when havering they would go back to the study 1 flash. Then when I raised altitude at full throttle the green LEDs would start flashing red above 200m. Fpv still showed a 12 satellite lock. I couldn't find anything while searching so any help would be great.
