SWB makes nice stuff, but all you may need is a simple servo arm with "X" offset, or maybe straight. So, the first thing you need to know... will you be crossing the cable or will they eb a straight shot. You'll need to look at you model carefully to decide which you want. Personally, I've always crossed them since no model I've ever had has lent itself to straight cables unless I was to do a lot of cutting of formers in the aft fuselage. Let us know and we can be of more help.
