in autorotation the txsm drag will yaw the helicopter and those fans will not help more pieces more problems more costs  |

When you kick full right or left depending on the rotation during autos you max the freaking tail rotor authority. When there isn't anything to kick.....well....I hope you enjoy spinning rides.  _________________  A walk in the woods helps me relax and release tension.

Help me out here - I’m not a helio pilot but I always thought that in autorotation there was no torque on the airframe. In this case it looks as though the tail rotors are electric and should still operate on battery power if you had to land Xwind?

no torque but you have drag on the stuff attached to the gearbox pumps generators etc,
even the gears, lube and bearings in the txsm will impart a little drag  a full left & right peddle are needed for maneuvering -  |
