In regaurds to your idea about flaperons for the coupe, I owned a Rans S-9 ( Mid wing arrobatic single seat) for about 3 years and it was equiped with a flaperon system. It had a max setting of 20 degrees and it made a world of difference. That plane had very small wing area and an airfoil built for inverted flight, not so much STOL. The way Rans made the system work was by using teleflex cables to move the ailerons. They were mounted in a bracket that slid up and down with a flap lever. By raising the lever the bracket would raise and pull both ailerons to 10 or 20 degrees and still maintain complete aileron control. It is a very simple system and might be worth looking into. My coupe is such a basket case that it would be quite some time before I would even look into flaperons. Thats ok though in a couple of short years there will be one more coupe flying again!

When I got my coupe - an overweight conversion to a D...with lots of radios/ instruments, etc...I was concerned about climb performance out of the 2100 AGL field I was using.... I had read about Coupe's poor climb performance, etc....BUT, I was getting 550 - 600 f/m even in the hot summer at 1400 GW. I was pleased with the climb performance. On close insepction when I rebuilt the Coupe (1984), I noticed that the aelirons were drooped about 3/8 inch from trailing with the stub trailing edges. Equal amount on each side, when the controls were in neutral.... At first, I started to correct this discrepency...then , second thought...Maybe this is why I get such good climb out of my ercoupe...as compared to the magazine articles....so I left it alone. I recognize I might loose some top speed, but I have been happy with the performance and especially with the climb rate..... Now, suppose one could mount the aeliron bell cranks on a sliding mount so the ailerons could be drooped at will by the pilot......giving flaps for landing and take off performance, yet re-alinged for in flight performance... I know, It requires engineering and FAA DER approvals, etc...maybe Experimental Desigination, while developing, etc..... But after considerable thought I think the slide mounting might be the simpliest solution. Other options could be extendable push rods, etc....... One needs to keep it simple and also safe so one side doesnt extend while the other side doesn't, etc.... So, Pete and Larry,....and others, here's a project to work on during those long winter nights....
