R1 Wurks Mega & Micro capacitor for Digital 3 ESC

R1 Wurks introduce their new line of Mega and Micro capacitor for the Digital 3 ESC. The Mega cap was designed to maximise the performance of the Digital 3 ESC with more than 30x the capacity of the built in capacitors while delivering ultra low ESR performance. This means that these capacitors respond to the ESC ripple current faster for better overall performance. Our 60 grams Mega cap also balances the side by side weight of the ESC, while sitting on the same footprint. This acts as a balancing ballast next to the Digital-3. This means you can also optimise the side by side weight balance, for harder launches. The 30 grams Mega capacitor fills in the gap for space constrained setups. The 30 grams Mega capacitor delivers maximum capacity on a smaller footprint, low ESR and unrivalled performance to weight ratio. The Micro capacitor is an excellent improvement over the stock Digital-3 capacitor, this is a smaller footprint, lower profile and delivering 3x the capacity of the built in Digital 3 capacitor. All the new capacitors will ship with a custom built cradle made of carbon fibre nylon filament and 3M very high bond tape.

Motiv RC 8200mAh Fat Shorty pack

Unique to Motiv RC, the fat shorty was made for RC applications where low CG is not necessarily most desirable but yet a shorty footprint is. The recommended usage for this battery is no prep drag racing and dirt oval. Due to this battery’s high 8200mAh, it will hold higher voltage longer during discharge than any other shorty made to date.

Team Powers Radon Pro V4.1 2S ESC

New from Team Powers, the Radon Pro V4.1 (2S) Speed Control is the next evolution of the Radon Pro V4. Sporting a limited edition casing with golden highlights, there is more fins on the case to better dissipate heat and lower the speed control’s temperature. Without the fan the ESC has a height of only 15.5mm for a low centre of gravity. Some internal components have been upgraded to improve the reliability while the software has also received some tweaks. With Limit Power and Limit Power Range, two function were added to control the initial power within a throttle range to adapt to different traction conditions, while the throttle frequency can now support 32KHZ with better linearity.

Muchmore super capacitor modules

Muchmore have released this pair of super capacitor modules for modified and stock racing. Low impedance, low heat generation, great start-up acceleration, the capacitor significantly reduces the interference generated by the high frequency switching of your ESC. Its small size and light weight makes it super easy to install.

Hitec RDX2 Pro dual port AC/DC charger

Hitec’s popular RDX charger line continues to expand with the introduction of the RDX2 Pro, a dual port AC/DC charger providing a whopping 260 watts of power. The RDX2 Pro features independent, 130-watt circuits, allowing you to charge two packs simultaneously. Its user-friendly jog dial easily scrolls through menus, making programming a breeze. Capable of charging 2S packs at rates up to 14A, and 4S packs up to 9A, the RDX2 Pro’s high charge rates provide more power in less time for your 1/8th and 1/10th-scale buggy and truggy needs.

RC Dynamics 1S Super Low ESR Power capacitor

From RC Dynamics, this 1S Super Low ESR Power capacitor helps minimises power losses to give greater performance. The primary purpose of the ESC power capacitor is to minimise power losses caused by the high frequency switching currents generated during motor commutation/control. The goal being to maximise ESC performance and minimise the heat generated in the internal circuits. It is very important that the ESC has a power source with minimal source impedance. The latest LiPo batteries used in 1S on road racing now already provide an incredibly low internal resistance. Therefore in order for the capacitor to provide maximum benefit it must have an ESR (Effective Series Resistance) at the relevant frequencies, at least an order of magnitude less than the LiPo battery internal resistance. The traditional Aluminium Electrolytic power caps do not have such a low ESR. The RC Dynamics 1S Super Low ESR Power capacitor, is manufactured using the highest performance components available and is tailored to suit RC models powered by a 1S LiPo Voltage source. Prototypes have been highly successful, installed in the winning cars at the 2020 Stock World and European Championships, also at UK National level.

Reedy Zappers SG4 HV-LiPo 2S batteries

New for 2021, Reedy introduce their new Zappers SG4 HV-LiPo 2S batteries. Zappers SG4 batteries incorporate state-of-the-art LiPo chemistry with advancements in construction that result in incremental improvements in power output and internal resistance with huge gains in durability. Featuring a 3.8V/cell nominal voltage, meaning that the battery can be safely charged to 4.35V/cell. It is not a secret that more voltage equals more power, so there is no easier way to increase power and top speed than a higher charge voltage. Even when the typical 8.40V (4.2V/cell) charging limit is enforced, Zappers SG4 shine thanks to their inherently flat discharge curve, which results in higher voltage deeper into the race. Available in several configurations, including all-new 2S Slim Stick and 4S Shorty models, for a variety of on-road and off-road applications. A high quality, durable hard case helps prevent damage while embedded socket connectors keep power-robbing resistance to a minimum. Male ESC connectors are included.
