Fuji,
Gyroscopic precession from a normal clockwise-rotating (when viewed from behind) prop will produce a left hand swing (requiring right rudder) when the tail of a taildragger is raised.
The way to figure this out is as follows: raising the tail could be achieved by pushing on the top of the prop. Imagine placing your finger on the top of the prop, then follow it round, in the direction of the prop (clockwise), for 90 degrees. Your finger would now be on the right hand side of the prop, at 3 o'clock. So the force from the gyroscopic precession will be as if it is being applied at this point. If you were to push the right hand side of the prop of an aircraft, the nose would swing to the left.
Incidentally, when the aircraft is rotated, gyroscopic precession should, in theory, produce a yaw to the right. However, I've never heard anyone mention this before. Anyone know why this is? I'd guess that the effect is negligable compared to the slipstream effect, but I'd be intereste to hear if anyone knows for certain.
