RE: rudders
The best way to learn rudder control.. and learning it makes you a MUCH better flyer... is to buy a foamie that will take a beating and just fly rudder, elevator..... it helps your turns look more controlled and less axial... also helps in landing with crosswinds..... if you want to try some 3d... you have to know how to control the rudder... why not use it if it's there ?
