I had gotten a Nextstar for my wife to learn on. I flew it a few times and did not like it all that much. The autopilot device fights you when you try to fly it, unplug that thing as fast as you can. This was the first plane that I ever had to use left rudder on takeoff, it has way too much right thrust. I and others in my club could never get the thing trimmed out to fly all that well. This was an arf which was to replaced the Nextstar Select that I broke while showing off for my wife, it had issues from day one. To make a long story short all of the gear from that plane is now to be found in a Sig LT-40.

If you want to reduce the effect of the steering on the ground just move the nose wheel steering link in toward the servo center at the servo end, or out to the furthest hole in the arm at the nose gear itself. I believe that 15 degrees is the norm for nose wheel steering setup, any more than that will cause handling problems on the ground.
