Some stuff we fly simply needs -nor tolerates anything more than a breath of rudder in knife edge -
My 30% Dalotel needed just a little rudder
the old skinny fuselage pattern planes of yore with huge fins and rudders were awful - they fell sideways and adding more rudder just added more drag and upset things.
One of the beautiful things about getting proper rudder/fin to total lateral area sizing, is that snaps are much nicer as the plane easily -instantly yaws with little input.
