Coming from Reds Racing is the new clutch retainer, a conical washer that keeps the clutch bell in place even in the event of a bearing failure. The part is machined from special alloy steel for increased durability and it is simply held in place using the crankshaft screw.
Modelix Racing have introduced the Ultimate Racing M3T .21 nitro off-road engine. Based off of the O.S. B2102 square stroke engine, Ultimate’s latest power plant will offer exceptional and very linear power over the whole RPM range. The engine comes with a redesigned cooling head that is slightly higher compared to the B2102’s but its lighter weight will still keep the overall centre of gravity low. Also part of the updated package is a new carburettor with a redesigned high speed needle for optimised fuel flow, more stable idling, improved mileage and increased overall performance. Another area of improvement is the harder 7075-T6 aluminium backplate that reduced internal friction while improving conrod durability. Other features include a balanced and silicone-filled crankshaft, Japanese-made high-precision front and ceramic rear ball bearings, 6.0mm and 6.5mm venturi inserts and a 3-port sleeve and piston made from high-strength aluminium.
Italian company Reds Racing have introduced the all-new R7 Evoke V4.0 nitro off-road engine. Specially aimed at the use on low-grip and narrow tracks where the torque curve of the engine can give an advantage, the power plant has been redesigned internally for an improved fuel consumption and bottom torque. Reds Racing also worked on areas such as sleeve, piston, combustion chamber and crankshaft. The features list includes the proven HCX carburettor with Gen2 venturi, the Anti-Dirt sealing system, Diamond hard-coated backplate, a balanced crankshaft, and a brand-new cooling head design. The Mario Rossi tuned engine is also available pre-broken-in by Mario Rossi and also as Race Ready by Elliott Boots version to get you instantly into the action.
Coming soon from Maxima is the 2147 Dirt exhaust system. The EFRA-homologated pipe features a hard-coated surface for wear and easier cleaning, compared to standard polished exhausts that can become unsightly due to dirt and exhaust fumes in no time. On top of this the tuned pipe will also increase overall performance and it comes including a suitable manifold, silicone gaskets and mounting springs.
Nuclear R/C Japan have released a first image of the ASM brand .21 competition nitro on-road engine. ASM will have two 3.5cc engines available at the beginning with more to come in the future such as an engine break-in service and more. All information and more images of the engines will become available in time for the release.
Available now is ProTek RC’s new Euro LS-5 3.5cc 5-port competition nitro off-road engine. Developed by top AMain and Novarossi pro drivers the engine will provide optimal power, run time and ease of tune. The power plant comes with a composite carburettor that resists heat and holds a consistent idle while the crankshaft and 5-port sleeve have been paired to provide linear power that produces a level of drivability that shreds lap times—throttle response is consistent throughout the entire RPM range. The setup of the long stroke engine allows for nine and a half to ten minutes of run time and to comes including a C6TGC turbo-style glow plug.
Reds Racing have introduced the all-new R5 Racer V4.0 nitro off-road engine. The R5R features a new 5-port sleeve and crankshaft timing for improved fuel efficiency and drivability and the sport-level engine also utilises the HCX horizontal carburettor, a tuned, silicone-filled crankshaft, a high-sealing front bearing and a chrome-steel rear ball race. The power plant comes hand-tuned by M. Rossi, it is hand- and compression-checked and suitable for both buggy and truggy racing alike.
XRD have introduced the F.T. Line Atomic .21 nitro on-road engine. The 3.5cc power plant features a completely redesigned sleeve and updated crankcase ports. The new cooling head is machined to sit lower on the crankcase for a low centre of gravity effect and the carburettor is equipped with reshaped needles for improved mixture flow. As with every F.T. Line engine, the unit comes hand-checked with an individual certificate of authenticity.
