No, it is a helicopter. It uses two rotors, one for lift and the other to
counter the torque of the main rotor. This design is (I believe) more popular
among Russian designs than any others.
Popular helicopter rotor systems include a primary rotor with a tail rotor,
two primary rotors on opposite sides of the VTOL (think Chinook), and two
contra-rotating rotors above each other (mine).
The secondary rotor of a helicopter doesn't have to be on the tail, it just
has to counteract the torque of the main rotor.
