Tail Rotor
Don't assume the tail rotor is producing the same amount of thrust as an aircraft propeller. The blades are variable and might even 'go into reverse' if you need to yaw quickly in that direction. . . .
For an aircraft you can use the glide ratio, = L/D, to find out the Thrust of the propeller. Maybe there is a similar easy way to find the thrust from a tail-rotor.... Are there any helicopter engineers out there..?
