Default PIDs caused visible oscillation above 70% of throttle when flying straight. What is intresting, oscillations were also appearing on tight turns on throttle lower than 70%\r\n1. Lowering Roll/Pitch PIDs to 4/60/30 caused oscillations to go away, but tendency to drop the nose slightly increased\r\n1. I think \"nose dropping\" is connected to new I term behavior. I think so because despite AirMode copter was unable to old attitude immediately after cutting throttle and immediately after punching throttle up to stop the fall.\r\n\r\nToo bad I do not have BB Logs on that but I lost SD card last weekend somewhere on the airfield"}}
