RE: Trainer
The only problem I see with the NexStar, is that you are relying too much on the flight stabilization. That 9 year old that soloed with it probably couldn't do it with the stabilization turned off. IMO, learning without electronic help will make you a better pilot sooner. Unless you add this device to every model you build after the trainer, sooner or later you'll have to fly without it, and it might as well be the first plane.
