Default RE: Suggested Engine Size for Bi-plane

. . . but my goal is to have better climbing power than speed.
Speed (as in the kind that "is life") gives you momentum, which carries into climb. If you're doing "high alpha" or whatever they call the wing stalled, nose up maneuvers you would benefit from the 4-stroke turning the larger prop. To pull you up from a low inertia state.
