How does a twin rotor helicopter turn?
Tandem rotor designs achieve yaw by applying opposite left and right cyclic to each rotor, effectively pulling both ends of the helicopter in opposite directions.
Is the Ka-52 good?
So, yeah, the Ka-52 is a great helicopter. It can carry a wide range of weapons, it’s fast, and it has a decent range and flight ceiling. And if you ever have to fly against it or fight under it, watch out. Especially if you’re on a boat within 80 miles.

Is the Ka-50 still used?
It is currently manufactured by the Progress company in Arsenyev. It is being used as a heavily armed scout helicopter. During the late 1990s, Kamov and Israel Aerospace Industries developed a tandem-seat cockpit version, the Kamov Ka-50-2 “Erdogan”, to compete in Turkey’s attack helicopter competition.
