they said that it could even be used instead of the flight control surfaces during normal operations as it would reduce aerodynamic drag due to sticking bits of aileron and the like into the airstream
And the fundamental principles of flight have been in place for how long ? Not to mention the millions (billions) of [insert favourite currency] that have been pumped into aerodynamic R&D over the same period of time !
If such a fundamental change were possible, it would have happened by now ! Sure as a trim / emergency / whatever thing .... but for everyday use, I'll keep my ailerons thanks ! For those doubters .... one word .... BA38.
or moving them front and back?
When were you last on a longhaul flight as pax Cosmos2 ?
