Knife edge pitch trim ?

[Paul Horan]

    The NSRCA site's trim states that during knife edge if the model pitches to the canopy wing then increase wing incidence.
    I assume what they are trying to accomplish is by increasing wing incidence the elevator will carry more down.
    OK, how does elevator position tie in with rudder ?  Does rudder deflection cause the elevator to become more effective - thus
the pitch coupling ?

Thanks,
Paul
