I know thie is the extra forum, but as far as the nexstar the front wheel when aligned correctly will stop the pulling right on take off. It has to be slanted towards the left, trust me and try it if you have one, you will be suprised the rudder will not have to be used at all. I can knife edge with the nexstar my nexstar is fixed and ready to fly again now it is not a virgin crash model i can have fun with it
