84" Eagle 2 clone
 

HI, i'm currently building an eagle 2 sized up to 84", or 130% of the original, In my eagle 2 i have a supertigre 45 that has been great, What size engine should I be looking at on this project, I've seen st's new 90, but was wondering if that was overkill?
I might add I'll be doing aerial video and digital stills from this plane, had lots of success with the old eagle 2 and a minolta cheapie autowind, but onward and upward :)

If it were me I would throw in at least a 1.20, and 1.80 would be better, as you can then power other planes with the motor after you tire of the Eagle
