Zen Racing introduce the Zen-RS conversion kit that has been developed to offer the 1/12th racer a wider tuning window and a more neutral balance in all grip conditions. A revised pivot location helps the car to have a stable balance and the new chassis layout incorporates a bellcrank steering system. The bellcrank offers a true Ackerman effect, removes all bump steer if required and the new servo placement makes for a better balanced chassis layout. The battery location is adjustable with the pack being held in position by two LiPo braces which can be moved forwards and backwards in three fixed locations. Also included is the Zen adjustable rear pod and a set of front and rear ride height shims making for a perfectly stable race platform. Servo posts, centre shock mount and rear posts are also included in the conversion with a final update in the form of a diff thrust bearing. The thrust bearing and spacer take away the side load from the outer diff ball race offering better consistency and diff action under high loads. To complete the conversion an R5 based front end, side links, rear pivot and side spring set-up, AE centre and side shock, body posts and rear axle are needed.
