Mike,
I have heard and read good and bad things about the Nexstar, which is true about anything. Some people have good luck, others have bad. The first thing you will notice is the difference between 3 and 4 channel radio's, ie. aileron, elevator turns versus rudder, elevator turns. While aileron turns are easier, never forget and continue to practice rudder turns. I personally have never flown a Nexstar, so I cannot give an opinion, have seen several fly, they all flew great. I do have an Avistar, you can get an ARF from Tower for $99.00, add an OS .46 LA for $59.99, and Futaba 4EXA computer radio for 149.99, 10% fuel, glow starter, and a chicken stick. You've got all you'll need to get started. At about the same price of the Nexstar or even the Avistar RTF. You'll have to install the radio, engine, and fuel tank, but that is all good practice. I recommend the 4EAX because it offers you the ability to store memory for four models I believe. Which you will need as you get different planes. The Avistar is as forgiving and stable as a trainer plus you can do basic manuvers with it. It has less dehideral and a semi-symmetrical wing which lends to smoother aerobatics. Whichever you decide, have fun and fly safe. Hope this helps.
