OK Ralph, see my reply #3, you must be the guy I heard it from...please explain the process in detail, for us "challenged" individuals...(Like, say, me)

OK, it almost takes longer to describe than to do. These hinges are applied after covering with the film of your choice.
1) Cut two long strips of film covering, about 1/2" - 3/4" wide, depending on control surface thickness. For ½A's, 3/8" is wide enough.
2) Peel off the backing from both, and lay one strip adhesive-side up on a piece of glass (The adhesive won't stick to glass!)
3) Lay the other strip of film adhesive side down, with the desired amount of overlap - 1/4" is plenty; perhaps 1/16" or 3/32" for ½A
4) Set your Iron on the "adhere" setting, not on the higher "shrink" setting, and iron the two pieces of film together
5) Now cut the strips into "hinges" about 3/4" wide (1/2" for ½A's
6) Apply the hinges, with your iron on the "adhere" setting, over-and-under and side-by-side just like you used to do with cloth hinges. They should be very close to each other, without actually rubbing against each other. Don't pull them super-tight, just don't leave any slack. This will give you the greatest freedom of movement.
You can use Clear film, which won't cover up any designs on the surfaces, or use the same color as the surfaces and the hinges virtually disappear. I haven't tried it yet, but I imagine the use of Monokote Trim Solvent would obviate the need to heat-seal the hinges to the surfaces, and possibly result in an even neater, faster job! This would require the use of Monokote Trim Sheets; the kind with the sticky adhesive.
I have had exactly one Monokote hinge "failure". When the Cardinal crashed, the outboard wing broke completely off, and that broke all the hinges on the outboard flap. All the hinges on the inboard wing, and the stab-elevator were intact, and it was one impressive crash! I have a lot of faith in these hinges, even for large planes, as with increased wingspan comes more hinges!
One of the chief, and almost automatic, benefits of this system is a sealed hinge line, with no extra effort and no ongoing maintenance.
