The correct answer is the Luscombe 50 (Model 8). The Model 8 used the new horizontally-opposed small engines that had just been developed by the engine manufacturers. Just in case these engines didn’t pan out, the aircraft was designed with a round firewall to minimize frontal area and simple construction. Although it was alleged this might allow the installation of a small radial engine if the flat four did not work, none of the original design engineers recall that being a design consideration.
