How are control surface problems in wings having high bending dealt with?

Flaps and ailerons are weak in bending and have multiple hinges along the span. Also, as you can see in the photo, the flaps are segmented which not only helps to optimize the deflection angle over ...

Does the pilot always need to use stick to compensate roll caused by pedal?

Depends on the airplane, but normally there is some roll rate generated by yaw, so, yes, to some degree or another. It's called Roll/Yaw Couple, and sometimes, "secondary effect of controls"....

How does control system design ensure correct elevator position with the steering system unlocked?

This is a somewhat dumb question, but here's one take at an answer. The upside-down control stick with the rigging shown tries to remain vertical by gravity. If a wind gust tries to push the tail down,...

Why do the ailerons of this flying wing work oppositely compared to those of an airplane?

can you elaborate why this (adverse yaw) is more common on slow flying aircraft It may be a very good illustration of how Reynolds number can affect Lift to Drag ratios of airfoils and how Newtonian ...
