Hi all,
I'm having a bit of a problem when landing my RC Guys Decathlon. After touchdown, during rollout, I can't seem to steer the airplane. Our field is grass, so sometimes steering is needed to stay out of the weeds as the rollout goes on.

My tail wheel setup is the standard springs to the rudder horn rods, (Dubro heavy duty), attached all the way out to the ends. I increased the spring tension also. I'm using high rates on the rudder and while it helps, I just don't seem to have the control I'd like, (I've made it a weed-eater more times than I'd like!) Takeoff is no problem. Do I need a different tail wheel setup?

opinions?
thanks all!
