    Maybe you have already discovered that the stock tail rotor gear ratio of king 2 is not fast enough. It is only 1 to 3.2 (32t belt pulley and a 10t tail rotor gear). That means when the main blade rotates 1 cycle, while the tail blade rotates 3.2 cycles. Users are sometimes complaining that the tail is not stable and will yaw or drift when throttling up; it is because the tail blades are not generating enough force under this low gear ratio.

    A 43 teeth belt pulley will increase the tail speed ratio to 1 to 4.3. This is a common ratio that is used in many popular helicopters. With this new pulley, you will feel the tail of helicopter is more solid and locked.
