Hi all, I recently installed new propellers. Non carbon fiber. White color, with rectangular edges ( my original propellers became chipped and useless). Since installing, my Phantom 2 has displayed very "twitchy" hover, constantly making tiny corrections (more so than usual) whilst displaying a vibration on the rear left leg. Faster flying reduces symptoms. Firmware update did not remedy the situation. Anyone got any ideas? Thanks in advance for your time and help!!!
