I have tried that type of system in a Thrustmaster model http://www.thrustmaster.com/en_US/products/tflight-hotas-4 http://www.thrustmaster.com/en_US/products/tflight-hotas-4 (click on media to go to the gallery, the rudder "rocker" is visible in the 3rd-last and 2nd-last picture, on the back of the throttle). I have to admit that it is slightly better than twisting the stick, but still nowhere near the accuracy of actual rudder pedals.
