Coming from SMJ is the Kabuto R21 Model ’18 3.5cc nitro on-road engine. The power plant is based off of the O.S. Speed R2103 and it received a new liner, crankshaft and steel main bearing for improved low to mid range torque. The DLC-coated and tuned crankshaft features Tungsten weight balancing and the overall design ensures low fuel consumption even in the high-grip conditions the engine was developed for. The engine is available pre-broken-in to have faster access to its full potential.
Picco have introduced their new V1 Team Robert Batlle Edition .21 nitro off-road engine. Born to commemorate the victory of the 2017 EFRA 1/8th Buggy European Championship, the engine sports advanced features such as a DLC-treated crankshaft, and a rear ceramic bearing. The low centre of gravity cooling head features a different colour scheme and is a tribute to European Champion Robert Batlle, while the 5-port cylinder sports an updated exhaust timing to achieve more response in the low to mid RPM range. The engine package is rounded out by a 2099 performance exhaust kit that features a front pressure nozzle in order to optimise fuel consumption and tuning.
Capricorn introduce the new ONE restrictor set. Provided in three different heights but all with 9mm diameter, the restrictors have been designed to be used on all Novarossi and OS on-road engines to fine tune the response of your engine. The shorter restrictor is meant to improve the bottom end power, while the longer one increases the top speed, all three giving different feelings to the user.
Reds Racing have introduced their new WR5 Black Diamond LTD engine. The Limited Edition engine utilises 5-ports, with special features based on the famous R5T Team Edition engine that has been a staple in the Reds lineup for 6 years. Available in two different models, the WR5 Black Diamond and WR5 Black Diamond HE High Efficiency, the latter version features low fuel consumption and smooth power band for high drivability. Reds have also improved the engine with a Black Diamond DLC Coated crankshaft which can last approximately 3-4 times more than a standard crankshaft thanks to the extreme hardness and low friction of the diamond coating. Even the conrod life is increased by about 50%. Supplied with an improved HCX carburettor featuring a new Flow Improved low speed needle and new 7075 aluminium fuel intake for improved tuning stability in extreme temperatures. Finally, the WR5 comes with a brand new black gloss cooling head which features an innovative design for improved air flow in order to increase the cooling and guarantee a low centre of gravity. The new cooling head is 10% lighter than the previous 5 ports generation.
Making their debut this week at the Tokyo Hobby Show, OS Speed have introduced a number of new items to their range. First up is the Max R21 1/8 on-road racing engine aimed at club racers, the spec of which can be found below, to be released in December. Next up a pair of OS Speed piston clip pliers to remove and set in piston clips. The tips of the pliers are curved and the inner side of the tip is grooved to hold a piston clip tightly. Finally there is OS Speed maintenance oil, available in 30ml bottles, an after-run oil to help increase the life of your engine.
Novarossi have introduced their new limited edition Karma 3.5cc off-road engine. Of a square stroke design the 4-port power plant will offer linear power output and low fuel consumption and it features an O-ring sealed combustion camber insert and a reverse-type composite carburettor.
Coming from O.S. Engines is the 21XR-B Version II 3.5cc nitro buggy engine. Targeting club-level racing the re-designed long-stroke engine features an easy-to-tune 21J3-I carburettor, a new aluminium cooling head for improved heat dissipation and it is upgradable using various O.S. Speed parts for areas such as the outer and inner heads, crankcase, crankshaft and more.
SMJ have introduced new Turbo-style glow plugs in four different heat ratings for off-road and on-road engines. The P3 is an ultra hot off-road glow plug for low ambient temperatures that provides stable idling, making it ideal for all run-in tasks. Next up is the P4 super hot off-road plug for low ambient temperatures while the RP6 hot on-road and RP7 medium on-road plug are made for low temperatures and all-season weather respectively. The Japan-made plugs are available separately.
