The main thing I was trying to say is that when it comes to aileron placement you want the stiffest aileron possible. I've never heard of moving horns off center to reduce tip flutter either.

My reasoning for locating the horn in the center was quite simple. The stiffness "k" of a shaft in torsional vibration is inversely proportional to length "L" of the shaft:

k = JG/L

k is stiffness
J is the second moment of area
G is the modulus of rigidity for the material
L is length of shaft

Here is another mind numbing math link for those who want more:

So making the free length as short as possible will make it as stiff as possible. Since we have one servo for each aileron in VMS's plane the best horn location for stiffness would be in the center (total length/2). If there were two servos for each aileron the best location would be at 1/3 and 2/3 length and so on. Following this logic a torque tube strip aileron is the worst setup possible for inhibiting high speed tip flutter because the constraint is as far as possible away from the vibration source at the tip.

I remember your rare Duelist kit now. It's a beauty. If you look at those torque tube ailerons on his plan you'll see he was trying to cure highspeed aileron buzz on his prototype by adding more hinges. When you build it I would recommend locating the servos at mid aileron span for the reasons outlined above. It will scream with YS-45's!
