I also use the SWB setup.I definitely recomend a bellcrank.It takes all the load instead of putting the load on the servo bearing and causing premature wear.The SWB tray with the bellcrank alows you to set up the servos and linkages on the bench.I use Dubro lazer rod housings and the exit's to guide the cables through the plane.I'll try and get some pics if you want.
