Beechcraft 18
The basic Beechcraft model 18 has two radial engines mounted in the wings, a tail wheel undercarriage and an H-tail. This makes it similar to the Lockheed 10, Lockheed 12 and Barkley-Grow T8P-1. The cockpit windows are the best way to keep them apart. The Beechcraft Model 18 comes however in many different versions, of which some even with a single vertical stabiliser and/or nose wheel. These are described separately.
