Harry, your idea certainly has merit, however, it would appear that the rear spar would have to be the primary support surface for any flaperons. I had my Coupe stripped to the bone and the rear spar is really quite pathetic from a structural standpoint. It would take a sharp engineer to come up with the necessary methodoligy to make the flaperons safe. Whilst the winters up here may be long and dark, they are not long enough for this farm boy to come up with a plan. In short, it looks like it would be a huge undertaking involving the front spar, and someone from MIT.

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....
