RE: Another Nexstar Post !
If you are learning on a buddy box ( which you should be) there is no need for all of that junk on the plane, your instructor can more effectively teach you how to fly without them .. Every bit of it adds a tendency which causes the plane to fly worse, not better. Once you remove all of the "flight aids" the Nexstar is a great little trainer and it is quite a good flyer and can be really aerobatic. It also has good radio gear and a great little engine. Its a very good starter plane, and the flight sim that comes with it is the icing on the cake.
Just to show my students what the plane is capable once they get a little further along, I like to take off and immediately fly through a rolling circle on the 1st non test flight. And that is on the stock aileron rate setup. That being said, you can do this with most any plane if you know what you are doing[8D]
Having the rudder and aileron linked together is pointless if not just a bad idea. I dont see how you can steer the plane on takeoff roll like this.
