The Kyosho Ultima line has earned a strong reputation in competitive 2WD buggy racing for adaptable chassis dynamics and thoughtful engineering. The Ultima RB6.6 continues that legacy, offering a Readyset package that simplifies getting on the track while keeping the core performance traits intact. The inclusion of a 4-gear midship transmission gives a well-balanced drive feel for both practice laps and race heats.
At the center of the Ultima RB6.6 Readyset sits the G15 brush motor, a recent addition that provides strong torque and reliable throttle response compared with earlier sensorless brushless options. Combined with the Vortex WP Brush ESC 45A, the powertrain is tuned to be smooth under load and straightforward to manage for varied track conditions.
The Readyset includes a slipper clutch to guard the drivetrain from shock during heavy landings, plus bold, high-visibility body decals that help with orientation on the circuit. The Syncro KT-231P+ transmitter supplies easy-to-access trims and endpoints so drivers can dial in steering and throttle characteristics without fuss.
This model shares compatibility with a broad selection of standard Ultima RB6.6 components and popular optional upgrades. Whether you plan incremental performance mods or visual changes, the parts ecosystem supports steady improvements as your setup and skill evolve.
The Kyosho Ultima RB6.6 Readyset is a dependable platform for hobbyists who want a race-capable 2WD buggy that is easy to run and upgrade over time.
