This is an optional 25T Helical Pinion Gear, and is used for the Tail Drive Gear on the Synergy 766 helicopter. By switching to the 25T gear, this will provide an effective tail gear ratio of 4.7:1, which is suited for headspeeds between 1300-1850 providing a sped up tail rotor RPM compared to the factory provided 27T pinion. With this 25T gear, you are able to use up to 116mm tail blades for an increase in tail rotor authority.
