Narrative:

Made approach to full stall landing in tailwheel airplane on runway 2. Requested wind-check; wind reported as 360 at 6 knots. Landed on centerline on numbers in approximate 3-point attitude; but did not have tailwheel firmly on the ground. Airplane began to drift right; corrected with left rudder. Left rudder/tailwheel not effective; airplane continued to drift right. Airplane rolled slowly off right edge of runway between runway lights onto grass; came to halt about 50 feet to the right of the right edge of runway and parallel with runway. Tower asked if I needed assistance. I replied that I did not. I asked for and was given clearance back onto the runway. Turned left onto taxiway charlie; taxied to t-hangar with ground control. Examined tailwheel mechanism; found it to be working normally.2 hours later went back and made 3 landings in same airplane. Wind now reported 030-050 at 6-9. Made 3 full-stall landings; making sure to hold stick full aft. Airplane tracked center of runway perfectly.
