If you look at the picture I posted above, the light blue line would be the dogleg version. The aileron torque rod usually comes from the factory bent at a 90degree angle. If the plane is an ARF, it's often pre-installed. If you want differntial, bend the exposed rod to match the light blue line. The red line is how it comes from the factory. If you can bend it before installation, the dark blue line would be the way to go, a straight rod, just angled forwards.
