I have not seen a reason to have more on mine so far. The rudder seems very effective and I have taken most of my Aileron Rudder Coupling out except in launch and landing modes. I had a great day of practice with mine yesterday working on line landings preparing for the TNT and found that it steers down the line very well with the rudder. I now have about 3 hours of flight time and probably shot 20 landings with it yesterday working off my short zip start and never once wished for more rudder authority..
