Hello,
I tested my 3D model with the software Flow Design de Autodesk (see the message of Jukka http://www.rotaryforum.com/forum/showthread.php?t=43878).
I do not know if the values are exact but it is interesting to compare the various configurations.
First simulation without fairing, drag coefficient 0.715
The second simulation with fairing, drag coefficient 0.347
The third simulation with brought in landing gear, drag coefficient 0.285
The fourth simulation without mast nor head of rotor, where from the interest of a fairing of mast, drag coefficient 0.249
