Want to make a wasd keys and mouse controlled flying script

Hi, I have a question, does anyone know how to make a third person perspective flying script that uses the w key to fly forward but is able to change direction with the direction of the mouse. I want to make a wisp character as the main character in my game but I can't find any good tutorials on mouse and keyboard controlled flight. Mostly the thing I want is to have the other keys be left strafe, right strafe and slow down or stop for the s key. Also direction being governed by the mouse, only function the w key serves is throttle for acceleration. If anyone knows how to make it so the camera follows the direction of the player movement but always sitting directly behind the player in third person mode that would be great. If anyone could help me out with this I'd be super grateful... Thanks.
