I second the swb manufacturing hardware recommendation. Scott at SWB makes a high quality product and has alot of knowledge of giant scale set-ups. I spoke to him at length about pull-pull setup and his feeling was that the wires should be kept at right angles and not crosses. If you viewed the wires, bellcrank and rudder horn from the top it would ideally form a rectangle. He usually cuts long slots in the side of the fuse about 1/8" high so the wire can pass through without binding. He sells kits that are set up for specific planes so alot of the guess work is taken out of the set-up. He can even custom design you a setup if your provide him with the necessary specs and dimensions. Give him a call he'll be more than happy to discuss his products.
