Figure 8: Influence of tail size on glide performance of Microraptor.
From: Aerodynamic performance of the feathered dinosaur Microraptor and the evolution of feathered flight

Colour coding as before. Bold lines: large tail (as used in all other tests), pale line:small tail. (a) Speed-specific Lift-Drag polar. (b) Glide ratio against speed-specific aerodynamic force coefficient. (c) Speed-specific moment coefficient against speed-specific aerodynamic force coefficient.
