No, NO, *NO!*
Don't stop it from doing that.
Fred Weick explicitly designed
Here's the text from page 26 of the Ercoupe Service Manual:
"Free control wheels and check aileron travel; with control wheel at 90
degrees, ailerons should have normal differential action of 20 degrees
up and 10 - degrees down. With maximum control wheel deflection of 150
degrees, up aileron should rise to 50 degrees, up aileron should rise to
50 degrees and *down aileron should have returned to about 7 degrees
below neutral.*" [Emphasis added.]
The Coupe ailerons are designed with strong differential action. The
main cause of adverse yaw comes from the increased drag (both parasitic
and induced) from the wing with the */down/* aileron. Fred designed the
Coupe ailerons so the up-moving aileron goes so high it's virtually a
spoiler. The down-going aileron reaches a peak of 10 degrees down but
then retracts to minimize adverse yaw.
This was partially necessary for good behavior in a two-control plane.
But it's also seriously advantageous in any plane for the ailerons to
give you great roll with little adverse yaw.
Get and use the service manual and other appropriate documents for your
Coupe. You can get them from Skyport. Contact information is on their

____________________________
I haven't written this recently so it's time again.
If you haven't got the manuals for the plane, I strongly urge you to get
them.
Every Coupe owner should have:
Airworthiness Directives
Aircraft Type Certificate Specifications
Bulletins, Letters and Memorandums
*Parts *
*Service Manual* and
*AD Manual*s
Flight Operations Manual (specify model)
Continental Engine Operator's Manual.
I have also found the Continental Overhaul manual to be useful, even to
me as a layman pilot.
The Continental engine parts manual can be worth having to hand to your
mechanic, as needed, and maybe for your own use.
Both our major parts and support companies have these manuals and you
can choose your preferred source:
