Mark,

Of course it is what you prefere but there are 2 arguments left:


1 servo versus 2 for the ailerons

Balancing of aerodynamic forces so better for the gear and current
Mark:
3) Makes no difference to the gear or current use. The gears and motor see torque only, the bearings deal with the side loads imposed.

My argument
Each servo of the two has to withstand a part of the lift force especially in situation with high G-forces (loops).
To keep his position each servo will use electrical power from the battery for that.
Not when using 1 servo.

Dynamic no differences in throw by diffferences of speed
Mark:
7) This is not much of an issue with quality servos and careful setup. It does require proper setup, though.

My argument
Servo 1 has to go against the lift force, servo 2 is helped by the lift force! See point 3



edp,

I think flutter is often generated by the wing when the construction isn't good, no D tube etc.
With the torque rod the rudder has a fixed postion even when the wing distorts, another difference!
