I've found several questions about differences between pusher and puller aircraft, but the effectiveness of control surfaces was not discussed in any of them.
Consider the following three scenarios:
- A: Aerodynamic surface in undisturbed flow
- B: Aerodynamic surface with a puller propeller
- C: Aerodynamic surface with a pusher propeller
In what case is the lift force generated due to the control surface deflection larger? What differences are there between B and C?
