I apologize for my brief reply and I understand your frustration with me. ZAGNUT and CafeenMan have described what I failed to iterate. If both the elevator and stab are already covered, a strip of iron on covering like Monokote or Ultracote about 1.25" wide and as long as the span of the elevator can be ironed into the gap providing a seal. Start by using a piece of tape to hold the elevator at full deflection. Then with the iron at low temperature, tack the strip to either the stab or the elevator--whichever is easier for you. Using a straight edge or ruler, push the strip into the gap down to the hinge line. Use the iron to tack the strip along the gap and onto the other surface. Once everything is tacked down you can increase the temp on the iron to seal everything in the normal iron-on-film technique.

If you haven't already covered the surfaces, a lot of times you can modify the above technique to cover everything all at once. You're just using a bigger piece of covering rather than a strip. With this technique, you can eliminate hinges entirely and the covering material becomes the hinge. This is known as a Monokote hinge. I've used Monokote hinges on planes up to 1.20 size without any problems. If you're into bigger planes than that, I would be leery of using just the plastic film as my hinge.

Does this help or do I need to explain further?

Thanks,
