I just had the Nexstar ARF. You can get free (albeit cheezy) simulators online, and you don't need the AFS or whatever the RTF comes with. I chose a 6 channel computer radio, and the OS 46AX. Spent way less money than if I were to get the RTF, and had a better radio and engine to boot. There's no need for more than a basic 4 channel radio with that plane, but once you get to more advanced planes you'll start to want a more advanced radio. I'm currently using the computer program part of my radio on my second/third plane right now.
