CRAB - extract from the SL

In the various cases which resulted in the loss of yaw axis control, the action applied to the RH yaw pedal was not enough (amplitude/duration) to stop rotation as quickly as the Pilot wished.
As the aircraft continues its rotation, the Pilot generally suspects a (total or partial) tail rotor failure and decides either to climb to gain speed or to get closer to the ground.
In the first case, increasing the collective pitch results in increasing the main rotor torque and consequently further speeds up leftward rotation. This results in the loss of aircraft control.
Geoffers - remember it talks about light wind conditions only, because in any stronger wind the directional stability will stop the spin or slow it enough to regain control - it won't keep spinning like the one in the video.

Have any of the long-time 365 pilots here ever experienced fenestron stall/LTE that spun you round and round like that?
