Actually I feel that my reply was very helpful and informative. I wish you would refrain from such vulgar language as this is a board for all ages etc. Blasting us all because your problem had yet to be resolved by any of our suggestions is not the way to go about things. I myself have no clue as how to test the naza unit but agree google is probably your best bet if your looking for immediate answers. Please post the answer to your particular problem so we may all benefit from it. Thanks.
