I would leave it,..chances are the BRS being set back as far as it is ,,it's there for weight and balance instead of a lead weight on the tail,..I would do a weight and balance before removing it,.. if your weight and balance comes out true with the BRS installed,..then that's probably why it is as far back as it is,..you could remove it,,but you will have to replace the weight,,it can be less weight but it will have to go back further in the tail,..I sent you a private messege,, top right under your name is the private messege tab
