Yes, swinging and swaying all over the place like a drunken duck but Take-Off tip from Avsim flyer will help:
No wind!
1. Tail wheel locked (assign key for it there is no click spot in waco)
2. Controls all way aft (to your belly)
3. Gradually apply power, slowly dance on rudder
4. At around 50 mph eas up stick to neutral (at this speed rudder become more or less efficient), gently apply rudder to compensate gyroscopic precession and tail lift.
5. As tail lift slowly bring stick aft and you are airborne!
May also help to set trim nose-up all the way. ( then stick neutral)
