Following the a 10.5T version Scorpion now also introduced a 13.5T variant of their all-new RR-3420 ROAR-spec brushless motor. Designed using a black anodised aluminium high-airflow can and a 12.5mm high-torque rotor the spec racing motor is made for competition use and it currently awaits ROAR approval. Apart from being of 13.5T specifications the motor sports the same features as the faster 10.5T variant with a screw-type rotor surface for cooling, high-grade silicon steel stator material and high-purity copper wires.
Yokomo have introduced a truck load of new parts for the YR-10 formula kit as well as optional rotors for the Racing Performer brushless motors. Starting with the YR-10 options, first up is a hard graphite main chassis plate. Featuring the same design and thickness as the original chassis the part is made from much harder carbon fibre, making for decreased flex and thus improved handling on high-bite surfaces. The chassis is a direct replacement and usable on both carpet and asphalt tracks.
Scorpion have introduced their all-new RR-3420 brushless motor. Designed to meet ROAR specifications the motor features an 7075 aluminium case with heatsink design and several cooling openings that also allow to check the stator specifications. Furthermore the motor utilises high-temperature magnets and high-purity copper wires for minimal internal resistance. The stator material is high-grade silicon steel and a built-in cooling fan reduces the internal temperatures while a patented screw-type rotor surface increases flux density and maximises cooling. The motor is currently available as 10.5T variant and should get ROAR approval soon.
Capricorn have introduced their new 540-size brushless motors for 1/10th and 1/12th scale applications. Coming with a lightweight can that sports cooling ribs and large vent openings, the hand-built motors feature a balanced rotor and ceramic ball bearings for maximum efficiency and performance. The motor is available as 3.5T to 8.5T modified, 4.0T and 13.5T modified as well as 13.5T, 17.5T and 21.5T stock variant. As for the two 13.5T offerings, the modified motor is making use of a 12.3x5mm rotor while the stock variant comes with a 12.5×7.2mm rotor.
Reds Racing have introduced new high torque variants of their VX 540 13.5T and 21.5T brushless motors. Both offer increased low-RPM torque which can be beneficial especially in high-traction conditions while the top speed remains unchanged compared to the standard motors. The high torque variants, dedicated for blinky touring and formula racing, are also meant to run cooler and with a higher overall performance.
German company Ruddog have introduced their all-new RP690 1/8th scale sensored brushless motor. Developed in close cooperation with the company’s 1/8th scale racing team the motors offers high-class performance thanks to high-quality materials that greatly improve heat dissipation and overall performance. The motor is available as 1800KV, 2000KV and 2200KV variant for all driving styles and track conditions.
Muchmore have introduced the new 12.3x5x25.3mm D-magnet modified linear power rotor for the Fleta ZX range of brushless motors. Specially designed to give milder bottom end torque but improved mid-range power the rotor is ideal for touring cars but also all other applications where an easy driving feeling is helpful.
Coming soon from Trinity is the 24K Certified Plus stock racing brushless motor. Based on the standard 24K the Certified Plus went through specific checks to ensure maximum performance. First up the motor’s rotor asymmetry is being checked which is meant to be a crucial part in building a fast motor. Typically a rotor shows asymmetry values of 0 to 30 plus with Trinity’s Certified Plus motors not exceeding a 4. On top of this each motor comes with red-sealed ceramic bearings and pre-set timing specially dedicated for 2-cell off-road, 2-cell on-road touring or 1-cell 1/12th scale applications. The Certified Plus range of motors will include 13.5T and 17.5T variants, they come with dyno printouts and are available soon.
