Coming from Capricorn’s ONE brand is a new .21 nitro on-road engine. Completing their on-road range, the power plant utilises a hand-tuned crankcase, crankshaft and cylinder with the modifications improving the internal mixture flow. Other features include selected, ONE-branded bearings, with a standard ball race for the front and a ceramic bearing being used as main ball race. Optionally available are also full steel or full ceramic bearings. The engine package is rounded out by an anodised 2-tone cooling head in a black and golden finish and the ONE option conrod that was introduced last week.
Coming from Capricorn are two new ONE brand option parts for the O.S. Speed R21 engine family. Available are a high-precision CNC-machined conrod made from top-grade alloy as well as a tuned backplate that optimises internal mixture flow into the combustion camber. Both parts are available separately and they are usable on all R21 engines.
Available now from LRP is the ZR.32X Spec.4 5.24cc nitro off-road engine. Based on the previous ZR.32 power plant, the X Spec.4 variant features a new heavy-duty CoolDownMax cooling head and the XTEC PowerCarb 3 15S-2 carburettor. The 7+1 port short stroke engine is a universal fit for race and monster truck vehicles and it comes including a LRP Platinum/Iridium R5 glow plug.
Picco Micromotori have introduced the latest addition to their on-road engine range, the R1 Team DLC WC2017. The power plant is a limited edition run, tested on the 2017 Worlds track and featuring a different cylinder with updated timing that increases the bottom power to better suit the challenging French circuit. The engine is easily recognised by a new engraved cooling head, specially designed and dedicated to the event and maintaining the size of the standard version to obtain a low centre of gravity. As with the standard R1 Team version, the crankcase sports a designing concept that ensures more stable performance throughout a wider temperature range and thanks to its improved stiffness it is immune to any RPM loss caused by unwanted torsion. The WC2017 also shares the same double bottom-end adjustment carburettor for finer tuning and a better mixture flow. The crankshaft features DLC coating that prevents any oxidation and wear of the crankpin and the engine comes fitted with a ceramic ball bearing and a 7-port sleeve paired with a piston machined from high silicon material.

O.S. Engines have introduced the Speed 21XZ-B Spec. II Ty 110% limited edition nitro off-road engine. The power plant was used to win the Nitro Truggy title during this year’s ROAR Fuel Off-road National Championship in the hands of Xray’s Ty Tessmann who also gave the name to the new engine. Features include a 7.0mm venturi insert as well as a 90mm manifold for consistent idling and lower fuel consumption. The package is rounded out by a 4mm lower cooling head for an overall lower centre of gravity and also included in the combo package is a T-2090SC exhaust pipe. Beside the combo pack the engine is also available separately.

Capricorn have introduced their new Tesla GT Spec 3.5cc nitro on-road engine. The power plant features a redesigned piston and liner as well as upgraded bearings with the updates resulting in an improved power band, making the engine better suited for the heavier GT cars. Part of the new engine package is also a dual balanced and silicone-filled crankshaft.
Coming from Triton RC is the new L4 Pro Spec V2 Elite GT .21 nitro on-road engine. Designed for the growing GT classes the ROAR-legal 5-port power plant was developed and hand-tuned to provide super strong bottom end, midrange and exceptional top end performance for large GT racing cars with sacrificing fuel mileage. The carburettor low speed needle and housing design has been changed to provide even easier tuning than the previous version while the crankcase has been optimised for power and efficiency by manipulating the internal volume and angles. The cooling head is milled for easier engine mount driver access and a Swiss front bearing, with a special seal designed to prevent leaks, as well as a Swiss ceramic inner bearing provide ultra low friction and longevity. The package is topped off by an all-new DLC crankshaft for added wear resistance and durability.
