The [link=http://www.flyhobbies.com/combo.htm]Superstar 40 [/link] is a great trainer and very sturdy but Hobbico has a new one called the [link=http://www.hobbiconexstar.com/]NexStar[/link] that is incredible. It has an Active Flight Stabilization that keeps the plane flying level if a mistake is done. The parts assemble quite easy compared to the Superstar and its a whole package system so its a RTF.
I saw a 9 year old flying it with his dad and he soloed that same day. Quite an impressive trainer.
