Good explanation NKP S2, Buzz here. NKP has it right. We use the steering "tiller" for the major turns on the ground, and getting lined up with the runway. Once the aircraft is on the runway, the rudder pedal steering is all you need, and blends in easily with the flight controls. Among other things at work i teach people to taxi and do high power engine runs. (when i'm not troubleshooting mechanical / electronic gripes)
With the DC-3 i play with on my nights off, there's NO connection between the tailwheel and the cockpit.... well i guess i forgot the tailwheel lock. To steer you use the "opposite engine" to blow the airplane in the direction you want, push a lot on the rudder pedals, and tap on a brake or two every so often. It's like sailing a boat...... more art than science.
By the way NKP S2, do you play with "Stoofs"? , reconditioned US Navy S2F's? ]
