No need to worry about that one.

Here's the line from the safety code:
"9) ...nor should any part of the model other than the landing gear, intentionally touch the ground, except while landing."

Clearly, this rule doesn't pertain to us. I've never intentionally touched my rudder to the ground. It's happened a bunch of times, but on every one of those occasions my intent was to touch the tailwheel to the ground or to hover a quarter inch from the ground. That's my story and I'm sticking to it.

Actually I have done some intentional tail touches, but I've always yelled "landing" or "touch and go" first. The rule does make an exception for landings.
