I have attributed the aileron stiffness in my IVP to the aileron cabin-seal
boots rather than any linkage or airflow around the surface. There is no
resistance down low, and only at high altitude does it come into effect. You
might try flying high (with nasal O2, of course) and a de-pressurized cabin
to see if your stiffness goes away--if so, you too have normal stiffness
related to the pressurization of the boots. As such, gap seals would make no
difference.
