I am new to heli's, had a Blade CX2 and now have a HB 3, very basic and I can learn a little and pass on to someone else. I bought a S&D from Tower to learn a little more and moving up later to a 450. I have had a couple of Sim and am getting a 3.5 Real Flight for Christmas. They are about half price now that the 4.5 is out and take less memory on your computer. The FMS was in my HB kit but still have not figured out how to get it to work. A heli comes on the screen and I cant get it to do anything....Good Luck...
