I was actually looking for a bit more of a comparison, rather than opinions. The YS is in stock and costs a few dollars more than the Saito if I order it on line because I can buy the Saito for $319 +tax at the LHS. To order it from Horizon it's $339 + shipping. So, cost is close but power is greatest concern. I have a 110 on a 60 size mayhem but am concerned about it flying the Big Boy with the same authority. The mayhem weighs about the same as the big boy I think but has a smaller wing 72" compared to 80".
