RE: 60 size ARF
The real question is not which one is best. I see it as which one can you find. All the suggestions so far are very good indeed. 4-star, Tiger 60, Big Stick and the Escapade to name some. I have put a Escapade 60 together and set it up for a friend. I have a forty size escapade. Both fly good and are fun. The escapade is similar to a four star. Not as rugged. Maybe it is just me, but there seems to be less 60 size plane on the market. The 60 is the standard of all engines according to my old friend Larry Poesy (RIP). He and another friend, Louis Penrod (RIP) helped design the modern Enya 60 while stationed in Japan in the late fifties. They told me that the sixty is the engine of all glow engines and every other two stoke is just a modified 60. That may not may not be true. What I do know is the sixties I own and have owned have always been good and reliable engines.
I hope you find that perfect sixty size plane. You have been given good advice. I would say the Escapade or Stick.
