Mart,
You asked;
CEFOSKEY,
when are we going to see your bits?
Your request is a little unusual. But if you must,
this should satisfied your desires.
IFMU,
Your article says;
"In the new design, the vertical tail rotor is moved to a position similar to a submarine's propellers."
Let's see now.
The gross weight of the X2 is 5,300 pounds.
The engine delivers 1,452 horsepower.
Propellers can deliver a thrust of 5 pounds per horsepower.
No! No! Igor. Don't change the X2 to
a Nose Sitter.

OK. No more jokes. A serious question.
How come Russian-American Igors like tail-fans?
Igor Sikorsky is the father of helicopters that have tail-rotors, and
Igor Bensen is the father of gyrocopters that have pusher-props.
