Hi,
This is the information given on Midland Helis web site for the above part.

PV0379 : Auto-Rotation Tail Pulley - 30/50
Autorotation Tail Pulley for the Raptor 30/50. This gives a driven tail on autorotations. This item is standard on the Raptor 50V2.


I have not used this part as the Titan has a driven tail but autos fine.
From the description it sounds to me that the Raptor 30 has a non driven tail.
can someone confirm or correct this please?
