Hi Hoppy,
the 4* is a tame tail dragger, you're not going to notice much difference on the grass,on a hard surface a little rudder management is needed. On take off,don,t firewall the throttle or the plane will torque to the left,set the tailwheel so it turns less than the rudder, that helps to keep from over controlling on the ground,nice flying plane,have fun.
Have a goodun,John.
