Thanks every one for you copious posts. I'm still leaning toward a two stoke because I would like to keep the plane as light as possible but I also know that a YS .63 would weigh about the same as a .45. However I really don't want to pay up for the .63 since I'm going to hang it on a profile. Profiles ought to be light, cheap and fun (IMO) so you can really hang it out there without getting sweaty palms I'm kind of thinking a YS .45 and a MCP. Any further thoughts? Has anyone tried a MCP on a YS .45?

Thanks
JW

PS sorry for the slow post
