That depends on flight speed. Adverse yaw is strongest at low speed. A high-aspect ratio configuration will not be able to avoid adverse yaw, regardless of the degree of aileron differential. At high speed the same airplane might roll fine without rudder corrections, because then aileron differential will be able to compensate for the then low adverse yaw if ...

Based on my experience (seeing, not flying) with radio control models, no, not completely. I have seen "drag buckets" added to ailerons, as well as coupled spoilers, which can come close, but there are large efficiency penalties for drag buckets, and added complexity and weight for coupled spoilers. Coupled split aileron "drag rudder" ...

Can aileron differential completely eliminate adverse yaw? Absolutely. All you need to do is have the amount of aileron differential be controlled by a computerized fly-by-wire system that continually tailors the amount of differential to whatever part of the flight envelope (airspeed, G-loading, angle-of-attack) the aircraft is operating it, so that the ...
