Hi all,

He's right.
But before you start fine tuning the rigging, you need to double check the
rigging first.
I noticed that a crocked nose wheel can affect the plane's flying
characteristics.
So make sure the plane is rigged straight by pulling it along a straight
line for some 20 30 feet - watch that you leave the nose wheel straight and
go see whether the
ailerons are aligning flush with the center section. Also if the plane is 2
control see whether the rudders are straight and evenly spaced from the
elevator.
Now look along the trailing edge of both ailerons like a carpenter does to
check wood for straightness. ( I need help here from a native speaker if
that's not clear).
The trailing edges should not point up or down. They should appear as a
straight line. If not you need to straighten out first what others did over
the last 50 years with the wide mouth vise grip. (Mine appeared like a
wobbly line, no straightness at all).
Now do a flight test.
If the plane still shows a wing heaviness, then take the vise grip and bend
slightly down on the aileron.
By then you should be the most experienced aileron bender in your area and
can help fellow coupers getting their plane straightened out. :-)
Good Luck,
Hartmut

This is really important.
I had a trim tab on my coupe.
Didn't help trim.
Coupe manual said to bend aileron. I did not believe them.
Sent plane in to have rigging tuned. Big bucks, but no help.
Finally, in desperation, I followed the instructions in the manual.
After taking wide mouth vise grips all the way from one aileron end to
the other, I inspected the edge and seemed to have moved it not one
whit.
Discouraging, but, I went test flying, anyway.
IT WORKED!!!!!!!!!!!
In fact, I had over corrected and had to pull it back the other way, a
bit.
The lesson, to me, was that the guy who wrote the manual knew more than
I (or my instincts) knew.
I truly and strongly recommend that you try the bending routine.

Subject: [COUPERS-TECH] Bending Aileron
----[Please read http://ercoupers.com/disclaimer.htm before following

Flying my Ercoupe (1946 415-C) at cruise speed I must hold slight left
aileron to continue flying straight. If I let go of the control, it
gradually turns to the right. The faster I cruise, the faster it turns
to the right when I stop holding left aileron.
To correct the problem, the manual indicates I should bend the entire
trailing edge of the left aileron down 1/8 inch. I would appreciate any
advice on how to correct this problem without bending the aileron.
Thanks, Dennis Hatfield
