Kyosho Ultima RB6 Readyset

World Champion DNA embodied in a fully assembled Readyset!
Based on the ultimate buggy chassis with brushless unit and 2.4GHz R/C system installed!

Shortly after winning the 2013 Japan National Electric Off-Road Championship, the Kyosho ULTIMA RB6 claimed the 2WD Racing Buggy World Championship! This world champion chassis has been enhanced with easy control and handling in this Readyset. The black anodized Duralumin main chassis provides superior strength and durability in combination with the uniquely designed resin side guards to maintain rigidity in pitching direction while using flexibility for roll direction. In addition, increased height of the chassis bottom under the rear unit limits contact as well as produces greater stability and control under a wide range of conditions. The inverted gull wing shape of the rear suspension arms realize progressive shock movement that makes it hard for the suspension to bottom out and utilizes the full range of suspension stroke to deliver secure road grip. The set is fully equipped to race with advanced setting parts such as 3-stage caster angle adjustment. At the center of the power train is a sensorless brushless motor that delivers more than enough power through the ESC specially designed for the RB6 that can be used with either Ni-MH or Li-Po batteries. A pre-cut and pre-painted body is also included in this fully pre-assembled Readyset that only requires a charged battery for the chassis and batteries for the transmitter to run. This world Champion machine is designed to be easy to drive and the Readyset delivers this in an unbeatable package.
