=== Control reversal ===
{{main|Control reversal}}
Control surface reversal is the loss (or reversal) of the expected response of a control surface, due to deformation of the main lifting surface. For simple models (e.g. single aileron on an Euler-Bernoulli beam), control reversal speeds can be derived analytically as for torsional divergence. Control reversal can be used to aerodynamic advantage, and forms part of the [[Kaman servo-flap rotor]] design.<ref name="Hodges" />
