5. After the hinges have dried thoroughly, pull on them to make sure they are properly installed. The
hinges will probably feel a little stiff as it is almost impossible to get all of the glue out of the knuckle
joint. Spray each hinge knuckle with DuPont Teflon Silicone Lubricant or a similar plastic-safe lubricant.
Move the surface back and forth a few times and you will feel it loosen up. Wipe away any remaining
lubricant from the surface with an alcohol soaked paper towel and seal the bottom of the hinge gap with a
strip of Ultracote or Blenderm tape. Be sure to fully deflect the control surface when applying the tape or
Ultracote to allow full deflection once the gap is sealed. Repeat this process for the other stab/elevator
assembly.
6. Use your hobby knife to remove the covering from the slot in the bottom of the stab for the elevator
servo horn. You may want to brush a coat of alcohol thinned epoxy along the edges of the opening to
prevent gas/oil from seeping under the covering.
