New pilot here. Flew my Phantom 2 last week put it away no crashes no probs. Took it out yesterday. Turned on Remote, then turned on Phantom. All 4 indicator lights flashed 2-3 times then both rear indicator lights went out. Picked up gps showing 2 front green lights only. Tried to see what would happen to start the props. Pulled down and in, all 4 props kicked in, i pushed up sticks and the two front props flipped it battery side up. All 4 props were spinning, only front two spinning enough to develop lift. Went thru and calibrated IMU basic and advanced, no change. Any ideas how to fix this? I have read in other posts that when they crash hard that the LED harness can unplug, not the case here, the leds come on when started for 2-3 blinks so they work..., it there a diagonstic download that i can figure WTH is going on?
