RE: NexStar Trainer
I learned on the NexStar and loved it. I still fly it occasionally just to get some air under the wings. It's a nice trainer but as others have mentioned it is over priced.
I bought it because it had everything in one package and since I was new I didn't feel comfortable buying something here, something there, and putting them together. So, what I suggest you do is contact a local club and get an instructor. You may find they have a club trainer you can learn on or you may be able to find a great deal on a trainer. Before you spend any $$$, ask around.
Good luck!
