Servo mount is drilled and tapped. I'm not sure about the control horn yet. The bevel is deep enough that the linkage isn't in line with the hinge line. I haven't decided whether I want to find some different clevises or just deal with the differential in the radio. The location of the clevis and resulting linkage geometry was picked to put the clevis as close to the center of force of the aileron as I could reasonably get it. Using 75mph and 45 deg deflection, the outboard portion of the aileron will generate about 89oz/in of torque and the inboard about 90 oz/in.

The pushrod ends are from ConnectorsRC.com, the rods are from Goodwinds, and the clevis and ball links are from Dubro.
