My second plane was a 4*60 with an OS91surpass. It was recommended by someone who helped me get started in the "after trainer" phase. It's are real confidence builder. I will keep it forever!!!! I put the trainer radio gear and engine OS 46FX in another SIG plane called the Somethin Extra. That got my nerves going again!!!!!!! Fun to fly too, but very quick. Lands nice though. You won't go wrong with the 60. Good luck...........
