REFLECTOR: Heavy Ailerons

[Chuck Harbert]

Gordon, I understand that the ailerons get very hard to operate above 160 
kts  which might indicate that the wings are flexing enough to rub against 
the aileron torque tube if there is not sufficient clearance. Maybe some of 
the others have some ideas as to why they would only bind at high speed.

Let us know what finally fixes the problem. I understand you did a beaytiful 
job on the build.

Gordon, Steve mentioned this when I talked to him yesterday and mentioned
that you were going to remove the aileron "fences" to see if that made any
difference. I assume it didn't, since you wrote. I know that there was
another V that changed the position on the aileron crank which made his
controls very heavy as well, so I'd suggest you try moving it back to the
factory recommended position to see if it makes a difference, although 3/16"
isn't very much. I assume that the control cables move smoothly and that the
anchor connection inside the cabin is per specs.

Could the VG's ( in front of the aileron) have any affect on the air
loadings on the ailerons? I've never heard of any problems, but they are
designed to keep the airflow attached longer to the wing which could
conceivably load the ailerons.
