Apply epoxy to the control horn and insert it into the slot. Attach a servo extension and a safety clip to the servo. Wipe away excess epoxy using a paper towel and denatured alcohol. Attach the servo wire to the installation string and gently pull the wire through the wing as you insert the servo into the wing.
