The H9 Alpha and Hobbico Avistar are practically the same airplane, and I'm very impressed with both as trainers. It's windy at my club most of the time and a traditional design trainer gets corky fast. That said, I've watched many with their Nexstars get the job done out there. The Avistar is our hands down favorite though, and that's from experience of watching new flyers learn faster on it than anything else.
