"Limits" are : as little as possible!!!! Especially for nose gears - when the plane is taking off 1 degree of turn is toooooo much - well maybe 2 degrees
Seriously, you do NOT need much throw on a nose gear - I like to say if I can see it move, it is too much.....as far as tail wheels, no problem, if they can move less than the rudder, great! If they move the same, it is O.K. - the prop blast over the rudder will be more effective anyway.
