Upgraded my Phantom (original version) to 4.02 and now when I boost the throttle quickly to gain altitude, the craft is all over the place. I do have quite a bit of extra weight attached (FPV, Telemetry, Gimbal, External battery), but it has never been an issue before. Flight was fine before firmware update. See the attached video. I did reload the stock phantom settings after the firmware update. Any ideas? Interestingly enough, after the update I haven't been able to connect via USB to check settings.
