GP Escapade as a second plane with an OS75AX? Not much more than a 4 star 60 kit, which I would have to build.

I assume you mean the GP Escapade 61. An OS 75 AX would be fine in that plane. I have a Fox .74 Eagle IV in mine and it flies great. It might do as a second plane but be careful and get some help from an experienced pilot.
