Sorry, I probably wasn't too clear. This kit does not use surface mount horns for the ailerons. A single servo mounts on the bottom of wing at the center rib. This servo runs 2 control rods (L & R ). Each control rod is connected to torque rod which is inserted in and adhered to its respective aileron. I'm trying to determine which adhesive is best for the job. While the kit manufacturer suggests CA, several other sources recommend epoxy.
