Default Ultra Stick 60 rudder design question

Greetings, my Ultra Stick 40 (older, origional rudder) absolutely does not like knive edge; it wants to snap out to the canopy side badly. The rudder has a strong triangular shape, narrow at the top and wide at the bottom. I am assembling a US 60 now, and might build a new rudder since it is the same. It appears to me that the extreme triangular shape of a rudder will give a lifting force (bringing the nose up) as well as the yaw that it is supposed to be doing. (much like a v-tail works...)

Am I way off here? Thanks for any input!
