I'd like to point out one big advantage of a different type of seal than the one being mentioned here. The amazing ten dollar redneck gap seal blocks more high pressure air from "leaking" through the gap... and offers big advantages compared to the over-under fabric or rubber that has been mentioned. (The over-under method still leaves air gaps where the hinge lugs and pins are, and COLLECTS corrosive water, snow and dirt)
The big advantage to the amazing ten dollar redneck gap seal is that rain, ice, snow, dirt, global warming, Florida voting ballot chads, and everything else simply cannot fall onto or into the hinge pins or the small exposed pieces of steel tube. Guess what? Not only do you get the full air seal, you get NO more water in your hinge pins to corrode them. No more corrosion starting under the fabric where you had to cut it away from the hinge lugs (during covering).
And guess what, part deux? It looks slicker, and reduces the "surface discontinuity" drag from air flowing past the upper tail surface. And guess what, part troix? It's a LOT easier to install. And guess what, part quatre? It still gives your mechanic full visual inspection of the hinge and related structure from underneath. And guess what, part cinq? Any water or mud splashed on it from underneath will be able to drain off, or get washed off and drain completely.
The simpler, less high-falootin', "redneck method" will be the easiest to install on a Maule, Cub or any other tube and fabric tail. Won't work on Cessna elevators, sorry.
Simply save up ten dollars for the upgrade. Go get a roll of clear shelf paper. Not the colored stuff, the clear "satin" shelf paper stretches better and cracks less. Spend two of the dollars on the shelf paper... don't spend any more than that or your airplane will crash. Cut a strip 4 inches wide. Clean and wash your airplane's fabric. Lubricate your hinges with penetrant oil. Do a full safety inspection. Apply a thin layer of vaseline on the top of all the elevator hinge lugs (short tubes that the pin or bolt goes through). Do not get vaseline anywhere else but the hinge lugs. Make sure the elevator is in the full nose down (stick forward) position. Peel off the backing from the shelf paper a little at a time, and stick it down centered over the gap to the stabilizer side. As you stick it down, push the tape with your finger down into the gap before you stick it to the elevator. It is important that the shelf paper is NOT tight at any time, even with the elevator full down! Verify that the shelf paper is not sticking to the hinge lugs, so that movement of the elevator will not tear or shear or rip the shelf paper. Verify once again that the shelf paper cannot and does not introduce ANY extra friction or resistance to full elevator movement.
In a year or two when the UV weakens or cracks the shelf paper you just peel it off and do it again. You'll have five or six years' worth of seals on one roll. "Goof off" and "Goo Gone" which is essentially Xylene will remove the adhesive when you need to peel and clean off the old adhesive.
Now this last step is important. Take the other eight dollars and get a 12-pack of beer, and give me two of the beers at the next BCP fly-in.
