Sorry, I'm sticking to my U-bend story SUPER SIMPLE to make and use no matter the wire size. Zero slop, and the angle of approach to the horn doesn't matter. FWIW, it's been over a year since I took the pic of the controls in the pictures in my post from March 2010, and the white one easily has over 100 more flights on it, and the blue one about 40-50 more. Still ZERO slop.
