Ultimate Racing M3X V2.0 Ceramic .21 engine

Modelix Racing have announced the release of the new Ultimate Racing M3X V2.0 Ceramic 3.5cc nitro off-road engine. Manufactured by O.S. Engines and based on their square stroke Speed B21 Ty Tessmann II edition power plant, the UR M3X V2.0 Ceramic was designed to offer maximum power, performance and tuneability with the engine offering a smooth and linear power supply from low to high RPM. The carburettor, crankcase and crankshaft have been developed to improve fuel consumption while the ceramic main bearings further enhances the engine’s overall performance. M3X V2.0 Ceramic utilises the 21 J3 carburettor, it comes with a modified backplate for improved gas flow and a B2101 crankshaft for increased power at low RPM. The setup of the 3-port engine is rounded out by a 6.5mm venturi insert and a specially designed, lightweight cooling head.

Ultimate Racing fuel filter & exhaust gas cooler

Modelix Racing have announced the release of the new Ultimate Racing fuel filter and exhaust gas cooler. Both feature machined and red anodised aluminium cans that offer a heatsink design for looks and functionality. While adding visual impact, the fins can also help to reduce the temperature of both the fuel and exhaust gas which can lead to better idling, as well as slightly increased power and run time. Included with the fuel filter and exhaust gas cooler, the latter is being placed into the pressure line between the exhaust pipe and fuel tank, come plastic mounting clamps for easy installation. Both accessories are available separately or as combo package.

Ultimate Racing M4R V2.0 nitro off-road engine

Modelix Racing have introduced the new Ultimate Racing M4R V2.0 nitro off-road engine. The 4-port power plant utilises a tuned crankshaft and offers linear power supply at both low and high RPM combined with improved fuel mileage, exceptional performance and reliability. The main changes from the previous version are the new cooling head design as well as the last evolution of the carburettor which is even easier to tune and more stable at different RPM compared to the previous version. The cooling head is also used on the M5 engines and it is keeping the engine cooler for improved performance at high temperatures. Its lightweight design ensures a low overall centre of gravity while the diameter of the head’s central bore has been reduced for more reliable temperature measurement as the new design ensured temp guns will not touch the glow plug. The composite carburettor of the M4R V2.0 is made by Novarossi and of a reverse type with a sliding throttle valve. It provides high idle stability, more precise tuning and higher mid/top range power.

Ultimate Racing M3X V2.0 nitro off-road engine

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.

Ultimate Racing EFRA 2141 & 2142 exhaust systems

Coming from Modelix Racing are the updated Ultimate Racing EFRA 2141 and EFRA 2142 Off-road Super Strong exhaust systems. On both sets the location of the pressure tap has been modified for better performance and both come with the Fast-Lock pipe and manifold connecting system for easy and reliable connection of the exhaust pipe and manifold. Performance-wise the EFRA 2141 pipe provides a precise and linear throttle response in the low to mid RPM range with great top end speed while offering an easy to control power curve for very demanding tracks with sharp corners and hard to clear jumps. The EFRA 2142 set provides a precise and linear throttle response in the higher RPM range with a great top end speed, making it the perfect choice for big tracks with long straights where high top speed is needed.
