One area I always wanted to follow was the use/modification of the Ercoupe
aeliron system  into flap-a-rons ...the combination of aelirons with a
system of moving both aelirons down for flap action...... may be fairly
simple to do.

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....

Fly Safe - Have Fun


Best regards, 

Harry
