I just taught myself on the nexstar ARF. I used the brakes and the airfoils (ARF does NOT come with AFS) and after 10 flights took them off and realized the plane was much faster with out them so put them back on for 10 more flights. With a OS 55ax and a 2.4 7C I think I have the perfect package for me. The radio should last me quite a while. I took out the dihedral and added floats to have more fun. Good luck.
