MCD Racing have released first images of their forthcoming new DUOX gas-powered large scale touring car. The vehicle is currently undergoing several stages of testing with the final product being awaited to hit stores in the second half of 2021. No official details about the features and specifications are available yet but MCD promise at least a unique differential design and suspension geometry.
Serpent have introduced their new adjustable one-way front diff set for the S7XX series of 1/10th 200mm on-road cars. The drag-assisted one-way replaces the standard front diff and it enables the driver to still brake and turn in like using a diff, however corner exit drive and change of direction on-throttle is greatly improved. The set is a direct fit on the S750 and it also fits older generation S7XX cars.
WRC Racing have introduced their all-new ST2.1 1/10th scale front-wheel drive electric touring car kit. The car is based on the successful STX.7 platform and features the now-popular mid-front motor position for optimised traction and stability while sharing most spare and optional parts with its 4WD sibling. The car uses a carbon fibre double deck chassis construction, a fluid-filled gear differential as well as easy to adjust body mounts for quick adaption to different lids. The steering utilises WRC’s proven curved rail design and a low centre of gravity servo mount. An off-road-inspired battery mount uses rubber O-rings to secure the battery pack, doing away with the common use of reinforced battery tape or battery taps. Other features include ultra low-profile shock towers and shock absorbers while new low-friction driveshaft blades ensure an efficient drivetrain. The kit is already available.
Coming from MST and usable for their range of drift cars is a carbon fibre lower front bumper. The part is machined of high-quality 3mm carbon fibre and it is a direct replacement for the standard bumper, offering improved rigidity and looks. Included with the bumper comes mounting hardware as well as a chrome decal for decoration purposes. Beside MST’s own range of chassis the bumper is understood to fit other brand’s cars using the same mounting pattern.

AB Racing have introduced their dual cooling fans especially designed for the use with 1/8th scale vehicles. Designed, manufactured and assembled in Australia from local and imported products, the clever design utilises CNC-machined 6061 T6 aluminium mounts and a simple, but secure mounting system. The fans benefit from a brushless motor and dual ball bearing design, increasing longevity in harsh conditions and providing optimal cooling performance. The fans used are rated at 19.4 CFM – combined CFM of 38.8 for both fans – with a total of 18 watts of power for both fans combined. The fans can be powered directly with a 2S 7.4V or 3S 11.1V LiPo battery. The mount is designed to fit standard 1/8th scale motors with a 42-40mm motor diameter. The CNC machined aluminium mount helps draw heat from the motor and provide a strong mounting platform for the fans.
Coming from O.S.Speed is their new manifold for 1/8th scale on-road engines. Developed for the 2019 IFMAR World Championships and successfully used by World Champion Shoki Takahara, the manifold offers a smooth transition between the low and high speed RPM range and it is best used with the TR01 EFRA2098 exhaust pipe for high speed tracks or the recently released TR02 EFRA2165 pipe for improved torque in the low to medium speed range. Included with the polished and laser-engraved manifold come a high-quality silicone seal and mounting springs.

O.S. Engines have announced the soon release of their new 21XR-B Ver.3 3.5cc nitro engine. The sports engine incorporates the DNA of the ultra-successful O.S.Speed line, transplanted into a more budget-friendly package for the average racer. A newly designed crankshaft will improve engine response thanks to a different shape and timing while a more lightweight piston further assists with a crisp engine response on throttle input. The OSSpeed-style conrod will offer exceptional durability while a redesigned combustion camber insert optimises power supply especially in the low to medium RPM range while offering stable engine performance at high speeds. Other features include a redesigned cooling head, the engine uses the double adjustment 21 J3-1 carburettor and it comes with 6mm off-road and 7mm GT specific venturi inserts. The engine is available separately and also as buggy combo set including an EFRA2089 exhaust pipe and MB01-75 manifold or as GT combo set including an EFRA2042 exhaust and MB01-70 manifold.
Coming from OfficinaRC are their new CU-TE 1.75mm shims that are an ideal addition to their recently introduced AT21ST-A-T titanium pivot ball for the Awesomatix touring cars. CU-TE is a material that has a specific weight of 8.99, about 3-times heavier than aluminium. This allows to place a considerable weight in a small space. These shims have been designed to replace the SH1.75 shims used on Awesomatix models to adjust the roll center of the arms allowing racers to position weight at the lowest possible point. The shims come in sets of eight, enough to outfit a full car.
