Honestly I would put the OS La 40 in there and nothing more. It's a great little engine and easy to get going. Pulls the airplane perfectly, and it will do more when you are ready. My bro has one in his.
Btw I crashed my Eagle today. Radio interference, or severe downdraft...not sure but I hit the tops of a tree. The fuse smashed in the woods 200 feet from the wing. The front of the wing lost all it's ribs or splintered the rest. But from the center spar back it was completely perfect. Very minimal rebuild for how hard it hit, and had to drop from the tall trees. The fuse, only the fin was badly damaged, and the gears ripped out (a problem already with eagles). But the fuse was in pretty damn good condition considering.
Needless to say, this thing is strong.
