Ah, you found out why you need stiff ailerons, stiff hinges, stiff linkages, and counter balanced ailerons eh. If the previous statement were true a miniscule servo with no gear slop would be sufficient. Effectively by adding a larger servo, you are damping the system with its resistance due to its torque needed to move it off its assigned "spot".

<span style="color: rgb(255, 0, 0);">To help eliminate flutter, do NOT place your servo linkage at the aerodynamic center of the aileron. If its a kit, most likely, they predetermined this for you already. Place it at a prime integer value of the AC. 1/3, 3/7, etc.</span>

Enjoy your introduction into vibrations.
