Driven tail

From RC Helicopter Wiki
Jump to: navigation, search

A driven tail is a tail rotor that has power supplied to it during autorotation. This power, delivered by the tail belt or torque tube come from the energy stored in the spinning main rotor, leading to a slight degradation in autorotation performance.

Helicopters that do not have a driven tail will simply weathervane during autorotation; as there is no longer any torque reaction that the tail rotor needs to manage.
