Al, Your split elevator should have a range of movement of up 20? and down 10? (4.9" up, 2.5" down). By the old documents I've read, the pre-loaded spring should be adjusted so, when the controls are up against the spring, you should be gliding at 65 mph. Then, if you pull through the spring, you should get to the full 20? up travel for minimum flying speed (which you'd only do inches to a couple of feet above the runway). I sure don't know how to get it that way. What's the model of your Coupe? If it's an "E" or later, it needs no paperwork for the split elevator since it came from the factory with one. If it's a C, D or CD model, it should have a signed-off form 337 to be legal with a split elevator and Greg is right that a few STUPID FAA wienies have turned down paperwork for a few people around the country when they tried to make this upgrade. On the other hand, there're probably fewer than five FAA wienies nationwide who would detect the upgrade unless the elevator were a factor in an accident and they did extensive research. Some insurance companies might refuse to pay in such a case. Fred Weick, the Coupe's designer, told me he thought the split elevator was a very good idea and he wished he had thought of it himself. He put a lot of effort into having the Coupes fly the same at idle and full power and that's just what the split elevator does by letting the slipstream go through the split.
