Stall: 45 m/s (100 mph); requires 56 MW
Loiter Speed (least power): 55 m/s (120 mph); requires 53 MW.
Cruise Speed (least energy/distance): 73 m/s (160 mph); requires 60 MW
Lift/Drag ratio: 15
Hover (non-stall, using a helicopter approximation): 120 MW; downdraft 18 m/s.
The actual dragon had a Max Speed of around 120 mph. Would have been 160 mph if he hadn't been clumsy and stiff from his long sleep.
