i purchased a os .61 for one of my other planes thinking that it would drop into the stock mount, well it doesnt! so now i am looking for a new plane to put this thing in. i am still kind of a newb to this hobby, got an avistar and a hanger 9 f-22. so now i am at the point where i a really want something better (and bigger). since there is so many choices out there i was hoping for some advice. thanks
