It was a good article. However I don’t think it was entirely accurate. There are so many different receivers or separate stand alone stabilizer units now that can be programmed for any configuration and can be oreiented any direction and any way. Ask any of the heli guys? Heck when I flew helis I had a spektrum AR7200bx and had to program it so it would work setting on the side of the heli frame. Point is they can be put anywhere in the airframe and not just sitting in what would be the standard flat location.
