The Redcat Racing Kaiju EXT 1:8 scale brusheless 6S monster truck is a powerful beast which features a longer wheelbase, belted tires and a rear wing. The Kaiju EXT can handle a single 6S LiPo or double 3S LiPo batteries. If you prefer to run 4S through the Kaiju, you’ll be happy to know it is also capable of running a single 4S LiPo or double 2S LiPo batteries.

While the Kaiju EXT started off as an extended version of the original Kaiju, it has grown into a whole new beast. The Kaiju EXT has an extended wheelbase, along with some additional major performance upgrades. These upgrades include new belted tires, motor heatsink with fan, new motor mount, metal servo horn, rear wing and a new race bred body that includes a working air scoop.

The Kaiju EXT’s chassis provides the truck with a wheelbase of 360mm. That’s an additional 51mm of wheelbase over the original Kaiju. The original Kaiju is an incredibly fun truck to drive, especially while using a 6S LiPo to perform standing backflips and pulling wheelies at almost any speed. The Kaiju EXT is fully capable of the same backflips and even longer wheelies due to its added stability.

The Kaiju EXT’s chassis is super durable and encloses the entire drivetrain to protect it from rocks and debris. Three heavy duty sealed differentials, each with metal internal gears are designed to provide smooth performance and are completely tuneable. The center differential helps the Kaiju EXT perform like a race bred monster truck on or off the track.

The Kaiju’s power and high-performance comes from the Hobbywing 2100kv 4-pole brushless waterproof motor with a perfectly matched 150A ESC. All that power requires strength and lasting durability, and the Kaiju EXT has certainly succeeded. The Hexfly 25KG metal geared digital steering servo has been fitted with a robust metal servo horn for added strength. Steel CVA drive shafts with captured joints, steel internal differential gears, 17mm aluminum hex hubs, rubber sealed ball bearings, sealed drivetrain and extra durable plastics are some of the performance and durability components standard on the Kaiju EXT.

Licensed IROC Sniper M/T belted off road tires keep their composure at any speed, while the aggressive tread pattern finds traction on almost any surface. The IROC Sniper M/T’s internal belts eliminate high speed expansion and ballooning during donuts and wheelies. Since the Kaiju EXT is all about stability and handling, these tires are the perfect fit.

The Kaiju EXT was designed to be a high performance monster truck with incredible power, speed and handling capabilities. The Kaiju EXT’s aggressive race-inspired body features a working air scoop on the roof for additional cooling to the electronics. A large rear wing helps keep the rear of the truck planted at high speeds and adds stability during jumps. The Kaiju vehicles even include little luxuries like body clip lanyards that will help ensure your time is spent having fun, instead of searching for lost body clips. Once you drive the Kaiju EXT, with its incredible performance and lasting durability, we are confident it will quickly become one of your favorites!
