RE: Recommended trainer, Hobbico?
The plane that most people consider to be the best beginner plane is the HobbyZone SuperCub (just don't use the ACT feature). It can take-off and land on pavement, concrete, dirt or short grass. If you feel that you gained enough experience with your old plane to put you past the beginner rank, then consider getting the ParkZone T-28 Trojan.
