Capricorn have introduced a new backplate for the One .12 engines. The item was designed to accelerate the fuel and air mixture in the liner’s lateral port, resulting in improved fuel economy and smoother power delivery.

JC Racing Products have introduced their new liner removal tool for the use with .21 nitro engines. It features an outer tube which has a diameter of 15.80 mm with a sprung latch which locates in the exhaust port. When offered into the liner, a second plunger is inserted down the centre of the outer tube to positively hold the latch in a closed position – this helps with removal of liners which can become tight over time compared to when the engine is new from oil residue. The tool has been tested on bores from 16.20mm to 16.50mm and will remove liners which are smaller or greater than these sizes on engines such as Sirio, O.S., Werks, Reds Racing and similar. The tool is 3-D-printed in a high quality fibre impregnated nylon giving it excellent mechanical strength and durability.

Modelix Racing have announced the release of the new Ultimate Racing M3X V2.0 3.5cc nitro off-road engine. Like its predecessor M3X, the V2.0 is based on the square stroke O.S. Speed B21 Ty Tessmann II edition engine. The engine has been specifically designed for maximum power, performance and tuneability while offering super smooth linear power over the whole RPM range. The carburettor, crankcase and crankshaft have been developed to improve fuel consumption while the cooling head has been redesigned by Modelix. It is not as low as the B2102 lower profile but it is lighter so it keeps the centre of gravity as low as the B2102 while improving its performance in very high temperatures. Unlike the previous M3X, the V2.0 comes with the 21 J3 carburettor. Its high-speed needle holder has been redesigned for a better fuel flow cooling, lowering the temp of the carb, offering improved idle stability, fuel mileage and overall engine performance. In addition, the uniball joint of the carb slide has also been modified with two stoppers instead of one. With this new modified design, racers can easier adjust the angle of the uniball joint without having to disassemble the engine. Also the original design of the O.S. backplate has been modified. It has been milled to improve the gas flow going to the piston and the backplate now is made of 7075-T6 Swiss aluminium to improve durability of both the conrod and backplate. Thanks to its design, you can remove the backplate without damaging the conrod even when it is on its lower position (PMI). The lateral grooves allow to easily remove the backplate without having to use any tool that can damage it.
XTR Racing have announced the release of their new AR3 Tuned nitro engine for 1/8th off-road applications. The power plant is based on the last European Champion engine but incorporates numerous improvements and refinements with focus on maximum bottom and top-end power – thus the 3-port engine features a ceramic main bearing and diamond-coated crankshaft. The crankshaft is individually Tungsten-balanced and silicone-filled while thhe sleeve and piston set is specially selected and matched. Furthermore the engine features a 10-rib cooling head.

Reds Racing have released the V2.1 Tetra Clutch system setup specifically configured for the 721 Scuderia off-road engine. The clutch features aluminium shoes and four 1.0 springs which improve the 721 Scuderia engine power delivery. The clutch assembly combined with Reds Racing Clutch bells have proven to guarantee extraordinary fuel mileage in recent tests and competitions and the clutch set is available both with 32mm and 34mm diameter to make it suitable for any type of car. Optional parts to further fine-tune the performance include high Inertia flywheels for low acceleration, recommended for low grip tracks, and low inertia flywheels for high acceleration, recommended for high grip tracks. Using the configurable top plate and springs, there are also six other combinations to further tune clutch action: 1.0 and 1.1 mm springs and three preload adjustments with the top plate.

German Gimar distributor RCCar24.com has announced the release of new short and super short 1/8th on-road manifolds. The somewhat strange looking manifolds will improve top end power, however they are known for being quite noisy so they might be prohibited at tracks or events that run a noise restriction policy.
Rody Roem’s World Champion Products has introduced the new VSR04 3.5cc nitro on-road engine. The new and exclusive super long stroke .21 power plant is based on the popular O.S. Speed R2102 and features some additional “Rody” touches, such as the DLC-coated VS Bi-turbo crankshaft, the Euro Spec liner and piston and an O-ring protected combustion camber insert. The engine is designed for competition on-road racing and thus ideally suited for experienced users. The engine is available separately or including a VS2098/M2001 exhaust system.
