If I had a plane with dual servos that was really difficult to land without flaps, I would considering using them.

But I certainly wouldn't consider converting a single aileron set up to a dual setup in order to use them.

What I would do instead would be to cut the ailerons and convert the single aileron torque rods to work flaps and run the servos with either a single servo in the center, or add two more servos for ailerons
