Yokomo BL-RPX3 Competition ESC

Yokomo’s new RPX speed controller is finally here. The RPX3 is the new flagship model that surpasses the performance of the previous RPX speed controller. While maintaining the overwhelming power that reaches maximum RPM instantly, the throttle feel has been optimised by smoothing out the power delivery, adding a controllable characteristic that prevents breakdowns even when power is increased. An auto mode that changes boost in accordance with throttle is also included, enabling high-boost driving with a linear curve. The boost value can now be increased to a maximum of 75, whereas in the past the upper limit was 60, and instantaneous power has reached a level far beyond what was previously available. A dedicated programmer is required to change the RPX3 program and is now also available. They also plan to distribute firmware to update the old programmer (BL-R26P), but you will need to revert to the old firmware if you wish to change the program of the old ESC after the update.

Hobbywing EZRun Mini28 speed controller

Hobbywing introduce their new EZRun Mini28 speed controller built specifically for 1/28 scale racing. The ESC is extremely small (22mm by 14mm) and lightweight at only 5 grams and the shape is designed for ease of soldering and reducing unnecessary tweak, an important factor for a 1/28th scale racing car. The fully-alloy heat sink ensures that the ESC can dissipate heat and operates at a healthy temperature range while the maximum output current can be up to 30A. The ESC has many adjustable parameters, including PWM frequency, brake frequency, softening, Boost, Turbo and much more. It is equipped with two usage modes, the Zero-Timing which is more commonly known as ‘blinky’ and the ‘modified’ mode which allows power-hungry users to increase additional turbo timing in the software. The ESC also has a built-in BEC which can support a maximum output current of up to 3.5A and the output voltage at either 6V or 7.4V. This will ensure constant power supplied to today’s high-torque servos in the market. Simple and convenient, parameter settings, firmware upgrading and other operations can be established using Hobbywing’s OTA Bluetooth module and your mobile phone via the Hobbywing app.

JConcepts electronic power module

JConcepts has a new electrical switch that is custom built from the ground-up to help simplify and operate the electrical system on the vehicle. The programable unit can be used in LiPo or NiMh mode and gives indication of the battery power supply of the vehicle. The lightweight, all injection moulded case preserves the inner components and includes LED light showing LiPo mode, battery capacity level and handy push button for on and off control. The wire neatly flows from inside the unit to receiver and battery boxes and installs with industry standard plug types. The power module has locations for screws which align with many popular vehicles on the market so mounting of the module is neat, handy, and secure.

R1 Wurks Digital 3 1/8th Scale ESC

New from R1 Motor lab is the 1/8 Scale Digital-3 Wireless programmable brushless speed controller. Developed using the most advanced microchip processor and a robust proprietary software, the 1/8 Scale Digital-3 delivers the most technologically advanced features to date. Development of the 1/8 Digital-3 was focused on ultra smooth power delivery needed for competition level racing as well as supreme power efficiency. Compatible with use of up to a 6S LiPo Battery that allows for more power output. The controller offers the most advanced throttle and brake features to suit a wide range of driving styles. The unit features an A.C.L.C. (Advanced Component Level Cooling) system. This design allows individual encapsulated low resistance Mosfets (inner & outer components) to transfer heat directly to the upper heat sink. The system also comes equipped with an all new advanced commutation algorithm called ‘Cool Power’ to keep the motor cool and deliver powerful, yet ultra smooth acceleration.

Surpass Hobby Thunder 540 drift car motors

Surpass Hobby have released their line of Thunder 540 Sensored Brushless motors for drift car. The motor comes with pre mounted quick disconnect and plug-in connectors, which makes it quick and convenient to remove and replace the motor. More efficient internals and special can design mean that the high power output temperatures are reduced by 5% compared to the previous generation. The stator is made of 0.2mm silicon steel sheet, with an efficiency conversion rate of 94% and super oversized front bearing give high load carrying capacity and reduced resistance for a more smooth and durable motor. Available in 3 different colours, black, red and purple.

ProTek RC 8800mAh & 7100mAh drag spec packs

The RC drag racing community spoke and ProTek RC listened and is now launching its own line of drag racing specific LiPo batteries. The ProTek RC 2S 200C 2s5p 7.6V/8800mAh shorty pack and ProTek RC 2S 200C 2s4p 7.6V/7100mAh shorty pack are designed with a moulded hard case for added protection. Both ProTek RC batteries are outfitted with large 8mm output bullets for low IR connections between the ESC and battery, eliminating weight and clutter within the chassis of the car by not having plugs. Both batteries feature a 200C burst cell rating and the 2s4p and 2s5p cell configurations drastically help with the voltage drop from high amperage experienced in drag racing. The 8800mAh and lighter weight 7100mAh both have been rigorously raced and tested by ProTek RC Pro Race Team member Frank Ulbrik, and have posted some of the fastest recorded NPRC passes this year.
