EX-RR Drop Extension Unit w/Soft Spring by KO Propo
This is the KO Propo Soft Spring type EX-RR Drop Extension Unit. With this unit, the distance between the right hand and the throttle lever compared with the 3D extension unit can be shortened. Also, this is the soft spring type (included). The previous spring used was a progressive spring becoming stiffer as the wheel angle increased, but the new 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.
EX-RR included this unit. The EX-RR used an Aluminum wheel but this package uses the normal wheel (plastic). You can change this wheel to other options to suit your taste.
