SPower XS7TT TAKUMI Factory Edition Offroad Engine

Spower, the engine brand of chassis manufacturer Sworkz, has introduced a completely new performance platform in the XS7TT Takumi. The Factory Edition 1:8 Offroad engine follows the success of the hand-modified SOUL II engine series with the name “匠” (Takumi), meaning master craftsman, represents the dedication, precision, and engineering excellence behind this exceptional racing engine. Developed in close cooperation with O.S. Japan, the XS7TT Takumi features a square-stroke piston and liner design with a conventional 3-port configuration. This setup delivers an extremely smooth and linear power curve, giving drivers outstanding throttle control and confidence on any off-road track. At the heart of the engine is a DLC-coated crankshaft equipped with dual tungsten counterweights. This advanced design provides exceptional idle stability and ultra-responsive throttle feel, translating every steering and throttle input into precise and controlled acceleration. The XS7TT Takumi is equipped with the proven SPower carburetor, allowing highly precise tuning and adjustment. The responsive carburetor design enables racers to fine-tune the engine for varying track conditions, temperatures, and fuel types while maintaining consistent fuel delivery and outstanding drivability throughout every run. Combined with its highly efficient combustion chamber design and optimised internal components, the engine delivers outstanding fuel mileage, allowing longer run times, fewer pit stops, and maximum consistency during demanding main events without sacrificing performance. To further enhance performance, the engine comes standard with the exclusive SPower Boost rear cover plate, helping to stabilise airflow and improve engine consistency across the entire RPM range, from low-end torque to maximum top-end power. A specially designed inner seal featuring an O-ring significantly improves gas sealing efficiency, contributing to greater reliability and more consistent performance over extended racing conditions.

Reds Racing 321 Estremo Worlds Edition

Italian engine tuner Reds Racing has released the 321 Estremo Worlds Edition, a Limited Edition 1:8 Buggy engine developed from the championship-winning 321 Estremo platform. Winner of the 2026 EFRA 1:8 Nitro Buggy European Championship with Juan Carlos Canas Carrasco, the Worlds Edition combines performance and thermal management with exclusive components specifically designed for high-level competition. The exclusive Worlds Edition Cooling Head has been developed to optimise engine temperature management, particularly in high ambient temperatures and during extended runs. A more stable operating temperature helps maintain consistent carburetion and performance throughout the run, while improving overall engine reliability and repeatability. The engine is paired with the special 2143 XONE Worlds Edition exhaust system, featuring the exclusive OXD surface treatment. The OXD treatment provides increased resistance to wear, deterioration, and high operating temperatures, helping the exhaust maintain its characteristics over time. In addition, the treatment contributes to improved exhaust gas temperature management, enhancing engine performance and the overall efficiency and consistency of the engine–exhaust system.

Serpent SRX8e Gen4 1:8 eBuggy

New from Serpent comes their latest 1:8 eBuggy with the release of the GEN4 SRX8-E. At the core of the GEN4 is an all-new Factory Lightweight Competition Chassis, precision machined from premium 7075-T6 aluminum and finished with a durable hard-anodized coating for exceptional strength and long-term wear resistance. Designed from the ground up with versatility in mind, the new chassis is far more than a lightweight component – it is the foundation of an adaptable competition platform. Strategic CNC machining removes unnecessary material while preserving the rigidity required for precise suspension performance, resulting in a chassis that delivers competition-ready performance straight from the box. Unlike optional lightweight upgrades, this premium competition chassis is included as standard equipment with every SRX8-E GEN4 kit. The innovative design also provides exceptional flexibility for racers and future development. The chassis is compatible with both traditional block battery layouts and modern saddle battery configurations, giving drivers the freedom to tailor the vehicle to their preferred setup or changing racing conditions.

JConcepts BK Design 13mm Shock Pistons

A project from Brian Kimwald himself, BK Design Shock Pistons are now available as an option for 13mm shocks through JConcepts. The BK piston, machined in low friction Delrin material has opened a can of goodness racers have only heard about, until now. The prototype slotted piston, machined by BK using equipment purchased exclusively for the master of all RC trades, was for sure a late-night project. During 2016, finding grip with newly released mid-motor vehicles was a vicious hunt for low-traction dirt conditions. As track conditions advanced, finding grip wasn’t necessarily as high a priority, hence the delay in the BK piston introduction. However, as the hands of time move forward, vehicles are once again looking for an edge in grip handling due to their advanced corning abilities. The all-precision machined item has the makings of the latest winner from the JConcepts Speed Laboratory and can be tuned by the user. The latest BK pistons arrive with plenty of pre-drilled combinations. Test drivers have reported increased vehicle grip while utilising the exclusive design. The BK channel in the piston increases the volume of oil in the shock body acting as another chamber in the shock body to add consistency to the mechanism. During compression and rebound, a lot of disturbance is created inside the working area of the shock. The action of a traditional piston is very top to bottom with pass-through only allowed through dedicated holes and around the perimeter due to blow-by. With this design, the piston is passing fluid through 2 separate channeled sections while the entire disturbance area rests in oil which helps compartmentalise all activity.

Caster Racing NTO821.2 New Design Crown & Pinion

Caster Racing has a newly designed Crown and Pinion gear for their NTO821.2 and ETO821.2 1:8 Buggy platforms. Now Spiral Cut Bevel Gears, they will provide smoother & quieter operation as the curved teeth engage gradually rather than all at once, resulting in significantly reduced noise and vibration. Multiple teeth contact each other simultaneously spreading the force over a larger surface area to withstand higher torque. The new design also offers increased durability thanks to better stress distribution that leads to less tooth fatigue under heavy loads.
