Sorry if this has been written about, it probably has but I didn't search using the right words. I've had a couple minor crashed and my Phantom 2 V+ v3. and it's no longer stable while hovering and in order for it to stay in place I need to take control of the sticks. It sometimes drops altitude and or moves forwards/backwards. Otherwise it seems to be fine, even looks stable at higher altitudes but that could be deceiving since I'm not close to it. Some background info: I'm running in the NAZA setting, happens while running in GPS mode, ran advanced IMU calibration a few times, ran remote calibration, rebinded the remote, am running firmware 3.12, I've calibrated the compass, and it happens at various locations with at least 7 satellites. I'm assuming that this wouldn't be covered by the DJI warranty but any opinions?. Does anyone have any home brewed remedies to try? I'm thinking of sending it out for repairs to DroneFly, anyone have any experiences to share? Thanks for your time.
