DS Racing RCO Kansei Chassis Conversion Kit. This Chassis is a highly adjustable performance upgrade intended for the Yokomo YD-2 and Reve D RDX platforms. This conversion kit is designed to give the driver a wide range of adjustability and compatibility with parts from both the YD-2 and RDX. The Kansei chassis features a wide range of tuning features including multiple slotted servo mounting holes that allow the servo to move laterally with the chassis for correcting the steering link's alignment along with servo depth adjustment for tuning weight bias to your driving style. With flex in mind, this chassis has plenty of adjustments to increase or decrease flex, steering response, and overall stability by changing the number of supports in the front end or removing the chassis braces in the rear end.
