    Let’s get started! Wing assembly 1. Locate the 2 wing panels as well as the composite aileron control horns and base plates. Use a soldering iron or sharp hobby blade to remove the covering over the slots for the aileron horn and aileron servo mount as shown. Make sure you are doing this on the bottom of the wing and aileron!
  • Page 5 2. Scuff the portion of the horn that will glue into the aileron and secure with 30 minute epoxy. Wipe away any excess glue with an alcohol soaked rag. Insert the ball link between the horns to ensure proper alignment while the glue dries. 3.
