KO PROPO Drop Box Extension Unit Ver.2 For EX-RR EX-2 #KO-10645


The KO Propo Drop Extension Unit 2 features an updated angle sensor that improves durability and the operation feel for both steering and throttle. The design prevents deterioration of durability and operational feeling due to wear, which can be said to be the problem of contact sensors. Along with smooth operation feeling by smoother sliding, the durability is approximately 100 times greater compared with the prior sensor. Therefore, the best feeling of operation can be maintained for a long time. In addition, the updated sensor outputs a more linear signal to the Master Unit. You can control the ESC and servo with a detailed operation sense. The number of ball bearings supporting the steering shaft has been increased from one to two. The double-support type supports higher precision operation and reliability. The normal spring included in the extension unit has been modified. The previous spring used was a progressive spring becoming stiffer as the wheel angle increased, but the updated softer spring give a linear stiffness as the wheel angle increases. Since the spring tension can be adjusted, you can set the spring tension to your personal preference.

  • Color: Black
  • Increased the number of ball bearings that support the steering shaft for higher accuracy.
