its been done here in the uk, ill see if i can find pics, it works aswell!!
if planes didnt have rudders they would spin too. Am i rite?
partly right , most aircraft in a normal configuration need some form of vertical surface behind the c/g for directional stability, otherwise they would spin.
however, there are lots of tailless models out there including flying wings with no fins.
