Description of the Product

  • 43 teeth belt pulley increase the tail rotor speed ratio from 1:3.2  to 1: 4.3
  • with this faster ratio, the tail rotor is rotating faster and generate a bigger wind force
  • the yaw or drift of the tail when throttle up is greatly reduced, it is a must get upgrade of king 2.
  • This pulley must used with the longer belt provided.
Maybe you 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 complaining that the tail is not stable and will yaw or drift when throttle up; it is because the tail blades are not generating enough wind 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 using in many popular helicopters. With this new pulley, you will feel the tail of helicopter is more solid and locked.
