![[image loading]](http://wiki.teamliquid.net/starcraft/images2/d/d3/Banshee.png) The banshee has two rotors that provide lift, so there is no net torque on the aircraft. It shouldn't need a tail rotor. Helicopters with one rotor need a tail rotor, because the main one, in a classic, Newtonian way, wants to rotate the main body of the helicopter in the opposite direction of the rotor's rotation (equal and opposite reaction etc). ![[image loading]](http://upload.wikimedia.org/wikipedia/commons/thumb/b/b2/HH-65C_Dolphin.jpg/800px-HH-65C_Dolphin.jpg) If there are two main rotors, they can be made to rotate in opposite directions, cancelling out the toque... so there's no need for a tail rotor. ![[image loading]](http://upload.wikimedia.org/wikipedia/commons/thumb/8/83/Piasecki_H-21B_USAF.jpg/800px-Piasecki_H-21B_USAF.jpg)   | ||

I've always been more bothered by the fact that a machine with rotors is supposed to fly in space. | ||

A jet with 4 engines must be able to fly (for a certain distance) on one engine, which means its tail and rudder needs to be sized so that it can fly in a straight line with unbalanced thrust. Helicopters with multiple counter-rotating rotors are also designed so that in the event of one engine failure, both rotors can be driven by a single engine. This results in some pretty complicated mechanics, especially in a beast like the Osprey. So my assessment of the situation is that instead of cross-linking the two lift rotors so that both can be powered by a single engine in case of a failure, the engineers felt a tail rotor could provide sufficient torque to allow the banshee to fly in a straight line, counteracting the torque from the main operating rotor. Believe it or not, the tail rotor may have been the cheaper alternative of the two. Not only that, but the tail rotor is used for directional control. Some multi-rotor helicopters use differential torque for yaw control, but on the banshee this would also induce roll, and there's no room for cyclic rotor control inside the fenestrated rotors. A rudder would be sufficient at high speeds, but would not provide any maneuvrability at low speeds, which would be an incredibly poor design for a vehicle that has to stop to fire a missile. | ||
