    Hi, does someone have experience with this filter for P3P/P3A?

    I mostly would like to know how it works, if it has a wheel and need to be manual adjusted before to fly accordingly to the sunlight conditions or it auto adjust. Thanks

    They do not auto adjust. You must manually rotate the filter to set the desired brightness prior to takeoff.

    I believe that they are two polarizing filters and one is stable while one rotates. Same effect as a pair of polarized sunglasses and a LCD watch
