RE: Return to pattern
While you're on the F3AUnlimited site, also take a look at Andrew Jesky's Osiris. Same size. Flies EXTREMELY well on a 5s pack and I've flown it through every sequence including F3A. My son is currently flying it in intermediate, but it flies the advanced schedule very well also. I have not seen the WindS 50 fly, but there are many that have endorsed it. I don't think you could go wrong with either.
