I'm an instructor & I've flown & instructed with a ton of trainers. The Nexstar is an excellent training tool, particularly if you are not a "natural" (& if cost is not a particular issue). It easily covers all of the training steps from no-skills beginner to standard aerobatics. If you have some prior experience, or are a "natural" at model flying (a good clue is that you are a killer at three-dimensional video action games), then something cheaper & more sprightly would be better -- a Hobbico Avistar is an excellent trainer in that case.
