I have the Global .46 Ultimate Arf and it is great! A few winkles in the covering but flies "like it's on rails". Easy on take off if you lift the tail then rotate. Great roll rate and will knife edge all day long. I'm running a ST.45 and 11-6 mas so no unlimited vertical but very close. Stalls tend to drop a wing tip but softly. Landing are uneventful. This not a good choice for second plane but possibly a third depending on your experience.
