Default RE: Control surface trailing edges

Tall Paul,

Control surface shape contributes more than you realize. Turbulence begins at the TE and travels forward. Any shape that helps make a clean break when the air passes the surface helps prevent flutter. Flutter can be caused by the conditions you mention, AND by the airflow separating from the surface due to turbulence.
